Welding Tips for Beginners: A Practical Guide to Your First Welds

The first bead never looks like the picture on the internet. Most new welders spend their first weekend burning rods, chipping slag, and staring at a lumpy, porosity-pocked seam wondering if they bought the wrong machine. They almost never did — the gap between a beginner and a confident welder is almost entirely technique, settings, and safe habits, all of which can be learned deliberately.

Why Welding Feels Hard at First (And Why It Gets Better Fast)

The first bead never looks like the picture on the internet. You drag the rod along a clean piece of mild steel, the arc sputters, and when the slag chips away you’re staring at a lumpy, porosity-pocked seam wondering if you bought the wrong machine. Almost none of you did. The gap between a beginner and a confident welder comes down to three things: technique, settings, and safe habits — all of which can be learned deliberately.

Welding feels hard at first because a dozen variables are moving at once and you can’t see most of them. Your hand is traveling, the puddle is glowing, the arc is hidden behind a shaded lens, and your arm is already tired. Welding isn’t a talent you’re born with, though. It’s a physical skill, and physical skills respond to repetition in a predictable way. Once the basics become muscle memory, the curve flattens fast.

What to Focus on First

If you only remember three things from this guide, make them these:

• Arc length. Keep the electrode or wire tip close to the work. A tight arc is the single biggest difference between a controlled bead and a shower of spatter.
• Travel speed. Move at a steady pace and let the puddle tell you when to slow down. Too fast and the weld sits on top of the metal; too slow and you burn through.
• Puddle observation. Watch the molten pool, not the arc. What the puddle is doing is your real feedback loop.

Machine settings matter, but they come second. A beginner who learns to read the puddle can fix plenty of problems by adjusting their hand before touching a dial. Body positioning matters too: brace yourself so your hand travels smoothly instead of hovering unsupported. We’ll break each of these down later in this guide, along with drills you can run in a single session.

The Learning Curve: One Hard Week, Then Real Progress

Expect your first session to be humbling. You’ll fight the helmet, misjudge the puddle, and restart badly. By the end of week one, most beginners can strike an arc that stays lit and run a roughly straight bead. Within three or four weeks of short, focused practice, the arc feels stable, the puddle becomes visible instead of blinding, and you start correcting mistakes while you’re still welding rather than after you chip the slag.

Progress isn’t linear, but it is fast compared to most crafts. The welders who plateau are usually the ones who practice three hours once a month. Short, frequent sessions with one intentional goal — ten beads on arc length, ten on travel speed — beat long, unfocused marathons. Position work comes next: flat, then horizontal, then overhead and vertical, where self-taught welders often stall.

Why Learning Well Matters: The Demand Behind the Craft

Whether you’re picking up welding as a hobby or a career move, you’re learning a skill with real economic weight behind it. WeldingWorkForceData.com, endorsed by the American Welding Society, estimates the U.S. welding workforce at roughly 771,000 professionals as of 2025, with a national median salary near $55,600 and average hourly earnings of $26.76.

The pipeline of work is even more telling. AWS data projects that about 320,500 new welding professionals will be needed in the United States by 2029 — an average of roughly 80,000 welding jobs to fill every year between 2025 and 2029, as detailed in the American Welding Society’s analysis of the welder shortage. At the same time, more than 157,000 current welders are nearing retirement. Beginners who persist step into a genuine talent gap.

Where the work lives matters too. According to Bureau of Labor Statistics data cited by AWS, about 61% of welders work in manufacturing, followed by specialty trade contractors and repair and maintenance. Manufacturing, infrastructure, shipbuilding, and energy work all need people who can pass a visual and bend test. If you’re career-minded, that’s the landscape you’re training for — and structured programs like an Aluminium Welding Course show how formal training packages those skills into credentials employers recognize.

Skill, Not Credentials, Is the Real Currency

Here’s an encouraging fact: welding rewards demonstrated ability above almost everything else. The AWS Certified Welder program is performance-based and carries no prerequisite courses — you show up, you weld to a written procedure specification, and the test facility either accepts or rejects the coupon. There’s no degree requirement standing between you and a certified welder card.

That’s good news for hobbyists too. Nobody cares where you learned to weld if the bead is sound, the joint is fused, and the piece holds. The path from first arc to competent welder takes a few months of honest practice, and everything that follows in this guide — process choice, safety setup, settings, technique drills, and a 30-day plan — is the route. Start with the arc, keep the puddle honest, and the rest follows faster than you expect.

Choosing Your First Process: MIG, Stick, TIG, or Flux-Core

Before you buy a machine or strike a single arc, you have to make one decision that shapes everything that follows: which process you are going to learn first. There are four arc welding processes within reach of a beginner, and OSHA’s welding fact sheet describes them plainly. Shielded Metal Arc Welding (SMAW, or stick) burns a consumable flux-coated electrode. Gas Metal Arc Welding (GMAW, or MIG) feeds a consumable wire electrode under an external shielding gas. Flux Core Arc Welding (FCAW) uses a flux-shielded consumable wire. Gas Tungsten Arc Welding (GTAW, or TIG) uses a non-consumable tungsten electrode with inert gas shielding.

They all produce a weld pool that freezes into metal. What differs is how much the machine does for you and how much your hands have to do.

Process	Shielding	Forgiveness	Entry cost	What it teaches best
MIG (GMAW)	External gas bottle	Very high	Moderate (machine + gas)	Puddle control, travel speed, clean setup
Flux-core (FCAW)	Flux inside the wire	High	Lowest (no gas bottle)	Arc discipline outdoors, heat management
Stick (SMAW)	Flux coating on rod	Moderate	Lowest overall	Arc length, rod angle, position work
TIG (GTAW)	Inert gas + tungsten	Low	Highest	Precision, heat control, filler timing

MIG: the fastest route to a usable weld

MIG is widely considered the fastest process to become functional with, and the reason is simple: the machine regulates much of the heat and filler delivery for you. You point, squeeze the trigger, and watch a puddle form. That leaves your brain free to focus on one thing at a time, usually travel speed. The trade-offs are real, though. You need a shielding gas bottle, which means a supplier relationship and an ongoing cost, and gasless environments (wind, drafts) will wreck a shielding envelope quickly. Once you are ready to push past mild steel, our Aluminum MIG Welding: The Complete Practical Guide covers what changes when the base metal changes.

Flux-core: the no-bottle option

Flux-core wire welding works without bottle gas, which makes it the most practical option for outdoor or garage beginners welding mild steel. If you are working in a driveway, a barn, or a garage with the door open, this is probably your machine. Expect a learning curve of a different shape: gasless flux-core runs hotter and produces more spatter than solid MIG wire. That is a trade-off of the process, not a sign that you are doing it wrong. It also reverses polarity on most machines, which matters when you set up. For the specifics on when flux-core is genuinely the right answer, see Aluminum Flux Core Welding: What Actually Works in 2026.

Stick: the toughest teacher

Stick is cheap to start (a holder, a ground clamp, and a box of rods), requires no gas, tolerates dirty or rusty metal better than anything else, and forces you to learn arc length and rod angle because the machine will not do it for you. It is also the process most likely to frustrate a beginner in week one, since rods stick, restarts go badly, and the flux has to be chipped away before you can even see what you made. Learn why it remains the field standard in Advantages of Stick Welding: Why SMAW Still Wins, and pair it with our All Position Welding Rod Guide when you start running beads overhead and vertically.

TIG: the finish, and the fight

TIG offers a superior finish but demands far more hand coordination, which is why it is rarely the recommended first process. You control the pedal, the torch hand, and the filler hand simultaneously while keeping the tungsten clean and the gas coverage undisturbed. Most instructors will tell you to learn it second or third, once your arc discipline is already automatic. If precision work is your end goal, Aerospace TIG Welding: Standards, Techniques, and Training shows how far that skill can be taken.

One last framing device. Process choice is not a personality test, it is a logistics question: what metal, what thickness, what position, what environment, what budget. Answer those four and the machine picks itself. Everything after that is practice, and practice is the subject of the rest of this guide.

Setting Up a Safe Welding Space Before You Strike an Arc

Every welding disaster story starts the same way: somebody propped a piece of steel on a wooden bench, hit the arc, and watched sparks roll into a pile of oily rags. Hot work safety is not something you add later. It is the first thing you build, and it takes about an hour to get right. Before you plug in a machine, walk your space with a notepad and check it against the list below.

Start With Fire Prevention

Welding spatter stays hot long after the arc stops. A single pellet can land in a cardboard box, a stack of paper, or a rag soaked in solvent and smolder silently for ten minutes before anyone smells smoke.

• Clear a 35-foot radius of combustibles where you can, and cover what cannot move with a fire-resistant welding blanket.
• Keep an ABC fire extinguisher within arm’s reach, not on the far wall.
• Assign a spotter for any job that takes place above ground level, overhead, or where you cannot see the far side of the joint.
• Store solvents, paints, and aerosols in a metal cabinet outside the welding bay.

One rule deserves its own warning: never weld, cut, or heat a used drum, barrel, tank, or container until it has been thoroughly cleaned. Residue from fuel, paint, or unknown chemicals can turn a warm shell into a bomb. The same applies to hollow structures. OSHA requires that all hollow spaces, cavities, and containers be vented before preheating, cutting, or welding so trapped air and gases have somewhere to escape as they expand (29 CFR 1910.252). If you do not know what was in it, do not put an arc on it.

Ventilation: What “Adequate” Actually Means in Numbers

Welding fume is a genuine health concern, not a scare story. The CDC’s NIOSH lists metal fume fever, lung irritation, and long-term respiratory damage among the risks of poorly controlled welding exposure (NIOSH Pocket Guide). The good news is that the ventilation threshold is concrete, not vague.

Translated for a home garage: a standard two-car garage is roughly 1,200 to 1,600 square feet. With an 8-foot ceiling, that is around 10,000 to 13,000 cubic feet, so a single welder working alone can sometimes rely on natural ventilation if cross-flow exists. The moment you open a second bay door opposite the first, put a box fan in the opening, and crack a window, you are in a defensible position. If your shop is smaller, a properly designed local exhaust hood at the bench is the cleanest answer. For process and gas storage details, a supplier reference like Airgas welding supplies covers cylinder handling and ventilation accessories you may want to add.

Also worth noting: outdoor work sidesteps the whole problem. If you have open air and a light breeze, flux-core and stick processes let you weld comfortably without fighting fumes, which is one reason many beginners pick them first, as covered in the advantages of stick welding.

Screens, Power, and Work Clamp Placement

Arc glare causes the same injury as a sunburn, on your corneas. OSHA requires welding screens mounted roughly 2 feet above the floor — high enough to block flash for people walking by, low enough that they do not trap fumes or block airflow. Position them so a neighbor in the shop never catches a direct view of the arc.

On the electrical side:

1. Use a dedicated circuit sized for the machine’s amperage draw; a welder sharing a 15-amp circuit with a grinder will trip breakers mid-bead.
2. Clamp the work lead directly onto the clean base metal as close to the joint as possible. A clamp on a painted frame or a rusty vise forces current through a poor path, which shows up as an erratic arc and a weak weld.
3. Lay cables where you will not trip, and keep them out of puddles and off hot slag.

Layout: Give Yourself Room to Think

Arrange the bench so the machine sits behind you, consumables sit within arm’s reach, and the grinder has its own zone away from cutting discs and wire wheels. Leave a clear path to the door. Clean, bare metal welds better too, so include a prep station: a wire wheel, a flap disc, and a dedicated cleaner. This matters even more when you move into non-ferrous work, where preparation decides success, as explained in how to prep aluminum right.

Do the setup once, deliberately, and every session after that starts with striking an arc instead of moving junk out of the way.

Non-Negotiable PPE: The Safety Gear Every Beginner Needs

Buy the safety gear before you buy anything that makes sparks. A welding arc throws off intense ultraviolet light, molten spatter, and a plume of metal fume, and OSHA identifies metal fume exposure and ultraviolet radiation as the main health hazards of welding, alongside burns, eye damage, electrical shock, cuts, and crushed toes. Every item below exists to interrupt one of those hazards.

Your helmet, your lens, and the glasses underneath

A helmet with a proper filter lens is the first purchase, full stop. A passive shade 10 lens will protect you, but an auto-darkening helmet — adjustable from roughly shade 10 to 13 for stick and MIG, lighter for low-amp TIG — removes the need to snap your head down at exactly the right instant, one less thing to fight while you learn the puddle.

Wear clear safety glasses with side shields under the helmet, always. When you flip the hood up to inspect a bead, hot spatter and grinding dust do not pause, and a neighbor’s arc still throws UV across the shop. The helmet handles the arc; the glasses handle the seconds between welds.

Covering skin: jacket, gloves, pants, boots

Gear	What it protects against
Leather or flame-resistant jacket (or sleeves + apron)	UV burn, spatter, falling slag
Process-matched welding gloves	Heat, spatter, minor electrical contact
Heavy pants, no cuffs, worn over boots	Spatter dropping into boots or cuffs
Steel-toe, high-top leather boots	Crushed toes, burns, a rolling hot electrode
Helmet plus safety glasses	Arc eye, UV damage, debris

Wear a welding jacket or leather sleeves rated for the work. No improvising with a hoodie: synthetic fabric melts, and a flick of spatter against polyester burns straight into skin. Pants should be heavy cotton or leather without cuffs, because cuffs catch falling spatter. Boots should be high-top leather with a toe cap so a dropped rod cannot roll down into your shoe.

Gloves differ by process. MIG and stick want thicker leather for heat and spatter; TIG rewards a thinner, more flexible glove so you can feel the filler rod. Keep them dry — damp hands and wet gloves are how beginners feel electrical shock through the torch or work clamp. Clamp ground to clean metal on the work itself, and never leave a live electrode holder resting with a rod still in it.

Welding fume, the honest version

Fume deserves a clear head rather than a frightened one. Acute exposure can cause eye, nose, and throat irritation, dizziness, and nausea, and OSHA says affected workers should leave the area and seek fresh air immediately. Over years it accumulates: OSHA notes prolonged exposure may cause lung damage and cancers of the lung, larynx, and urinary tract, while manganese fume can cause Parkinson’s-like symptoms. NIOSH treats welding as an occupation needing ongoing exposure control, and the logic is plain: risk rises with exposure, so ventilation and capture are the controls.

Shielding gases carry a quieter hazard of their own. Argon, helium, and carbon dioxide are heavier than air, so they pool in pits, tanks, and other low or confined spaces, displace oxygen, and can cause suffocation. Carbon monoxide can also form during welding, so a room can feel fine and still be unsafe.

Fume composition also depends on what you are burning. The coating on a stick rod contributes directly to it, which makes alloy steel welding electrodes a safety choice as much as a metallurgical one. Unknown paint, plating, or primer is worth removing before heat touches the joint, and aluminum cleaner for welding shows how much prep changes what ends up in the smoke.

Practical fume reduction for a home shop

• Capture at the source. OSHA advises keeping fume hoods, fume extractor guns, and vacuum nozzles close to the plume source. A budget extractor arm parked inches from the arc beats one parked across the garage.
• Keep your head out of the plume. Fume rises. Weld to the side of it and set up so airflow carries it away from your face rather than across it.
• Ventilate deliberately. OSHA notes that welding outdoors does not by itself guarantee adequate ventilation — a windless day pushes the plume straight back at you.
• Add respiratory protection last, not first. A NIOSH-approved respirator with P100 or combination filters cuts fume intake, but it protects only you and does nothing for anyone else in the room. OSHA’s general requirements for welding, cutting, and brazing tie ventilation and respiratory protection together.
• Strip coatings and clean up wet. Paint, galvanizing, oil, and plating all change the chemistry off the arc, so grind them away first — and afterwards damp-mop or use a HEPA vacuum instead of a broom, because dry sweeping stirs settled dust back into the air.

Treat PPE as a fixed budget rather than a maybe. Helmet, glasses, jacket, gloves, pants, boots, and a respirator come before any power-tool upgrade, and none of it substitutes for a clean, clamped, well-ventilated workspace. Gear keeps you safe while your technique catches up.

Your First Kit: Machines, Consumables, and What to Spend On

Open any machine catalog and the message is the same: you need more. A multi-process rig with a digital menu, a $400 helmet, a rolling cart, a spool of exotic wire. Most beginners pour their whole budget into the machine and then run out of money for the things that actually decide what their welds look like.

The inversion worth remembering: in your first year, the machine matters least. Consumables, safety gear, and a handful of cheap clamps determine most of what a bead turns out like.

What a Starter Setup Actually Requires

Strip away the accessories and a working mild-steel starter kit is a short list. Until every box is checked, you aren’t ready to strike an arc:

• A welder (MIG, flux-core, or stick) with enough duty cycle for the material you actually own
• An auto-darkening helmet, plus safety glasses worn underneath
• A welding jacket or flame-resistant sleeves, and gauntlet-style gloves
• A chipping hammer and wire brush for stick and flux-core work
• An angle grinder with a grinding disc and a flap disc
• At least four clamps that genuinely hold parts in position
• A rated fire extinguisher within arm’s reach

Notice what’s missing: a fabricated table, a fume extractor, a foot pedal, a second grinder. Those arrive later, when a real need shows up. If your process uses shielding gas, add a regulator and a cylinder — most local shops rent cylinders rather than selling them, and our Airgas welding supplies guide walks through what renting, exchange, and refill pricing actually look like.

Where to Save and Where Not to Cheap Out

Save on the machine. A budget 140–180 amp MIG welder or a basic stick machine will out-weld a beginner’s technique for years, and multi-process units are good value if you plan to try TIG later. What you should not economize on:

• The helmet. You wear it every second of every session. A slow or uneven auto-darkening lens forces you to lift and lower your hood constantly, and poor optical clarity causes the eye strain beginners mistake for fatigue.
• Gloves and jacket. Thin leather cracks, seams split, and heat comes through where it matters. Replace cheap gear once and you’ll stop buying it three times.
• Consumables. A warped contact tip, a kinked liner, or a spitting gas nozzle creates feed problems that look like bad technique. Diagnosing a machine fault while blaming your hands is the fastest way to lose confidence.

Wire and Rod Selection for Mild Steel

For MIG, ER70S-6 is the default and the right answer. It contains deoxidizers that tolerate light mill scale and minor contamination, so a beginner who missed an inch of cleaning still gets a sound weld. It comes in every diameter from 0.023 to 0.045 inch.

For stick, two electrodes cover nearly everything a beginner meets. E6011 runs on AC or DC, digs hard, and tolerates rusty, greasy, imperfectly fitted joints. E7018 is a low-hydrogen rod that lays a smooth, tough bead and makes the cleaner, stronger weld of the pair, but it rewards clean base metal and dry storage. For why one beats the other, our advantages of stick welding breakdown covers where SMAW still outperforms wire processes, and the all-position welding rod guide maps which rods behave in overhead and vertical-up.

Shielding Gas Choices

For MIG on mild steel, a 75/25 argon-CO2 blend — C25 — is the beginner-friendly default: stable arc, minimal spatter, easy starts. Straight CO2 costs less and penetrates slightly deeper but throws more spatter. Self-shielded flux-core wire needs no cylinder at all, which suits outdoor and windy work, though the burning flux produces considerably more smoke, which matters in a closed garage.

Consumables That Affect Weld Quality vs. Accessories That Are Convenient

Catalogs blur these two categories, so separate them yourself. Quality-affecting consumables: contact tips, gas nozzles, liners, drive rolls, a regulator that holds steady flow, clean abrasive discs (a grinding wheel contaminated with aluminum will smear into a steel weld and wreck it), and clamps that hold parts in position. Merely convenient accessories: welding carts, tool chests, magnetic trays, work lights, stools, helmet racks. Buy the first group early and deliberately; let the second arrive as gifts.

The kit grows with the skill, not before it. Buy the machine, the safety gear, and the consumables, then spend months on wire and rod rather than gadgets. Every upgrade afterward will be one you can actually feel in the weld.

Arc Control Fundamentals: Arc Length, Travel Speed, and Work Angle

Machine settings take most of the blame when a beginner weld looks bad, but they are rarely the real culprit. Two welders can run identical voltage and wire speed and produce completely different beads, because quality is decided by three things your hands control: arc stand-off, travel speed, and work angle. The same fundamentals govern MIG, stick, flux-core, and TIG, which is why instructors drill them before anyone touches a joint. Get them right on flat plate and later skills, including those in All Position Welding Rod Guide: Types, Uses & Tips, come far easier.

Arc Length: The Diameter Rule

Arc length is the distance between the tip of your electrode or wire and the puddle. It is the most common beginner mistake because a long arc feels easier to see. A long arc wanders, spreads heat, blows away shielding gas, and throws spatter. A properly short arc gives a tight, even hiss and a puddle that stays where you put it.

For wire processes the same idea applies as Advantages of Stick Welding: Why SMAW Still Wins notes for stick work: keep the contact tip close to the work, generally within about 3/8 to 1/2 inch, and let the wire stick out only far enough to keep the nozzle clear. TIG is the exception: the tungsten never touches the puddle, but the arc gap stays short and consistent. Listen to the arc, because a steady sizzle means your distance is right and crackling and popping mean it is not.

Travel Speed: Read the Bead, Not the Clock

Travel speed is self-reporting. Run too slow and the puddle outruns your rod, producing a wide, flat, over-built bead that can distort thin plate or blow through it. Run too fast and the puddle chokes into a narrow crown that never wets into the sidewalls, leaving shoulders that look fused but are not. The target: a puddle slightly wider than your filler, advancing steadily with no pausing. If the bead sits taller than it is wide, slow down; if it is wide, flat, and gray, you are moving too slowly.

Work Angle, Travel Angle, and Body Position

Two angles govern the shape of every weld. The work angle is the electrode’s relationship to the joint faces, such as 45 degrees into a single-V groove. The travel angle is its tilt relative to the direction of travel. On flat butt joints, a 10 to 15 degree travel angle trailing the puddle, dragging rather than pushing, is the standard starting point in most courses. Tip the rod up too steeply and you get shallow penetration, undercut at the toes, and a rod that sticks; drag too far behind and the arc digs forward under the puddle.

Angles are only as stable as your body. Stand or sit with your forearms braced, feet planted, and the joint at a height where your wrist stays neutral. Move from the shoulder rather than pivoting the hand, and keep your head where you can see the puddle instead of leaning through your own smoke. The OSHA welding hazards guidance advises positioning yourself to avoid breathing welding fume, such as staying upwind outdoors, and the same stance keeps your eyes on the puddle.

Four Drills You Can Finish in One Session

1. Bead-on-plate rows. Mark a mild steel plate into six 3-inch strips. Run one bead per strip at identical settings, keeping width and ripple spacing the same. Compare them and circle the best one.
2. Speed ladder. Run four beads: deliberately slow, slightly slow, fast, and “natural.” Label them with soapstone; that becomes your reference for correct speed on your machine.
3. Angle anchors. Set a magnetic square at 10 to 15 degrees beside the joint, rest the electrode against it, and weld a full bead without lifting. Repeat until the angle feels automatic rather than counted.
4. Stop-and-restart chain. Run 2 inches, stop, restart with a slight overlap on the crater, and continue. A dozen of these teaches the overlap habit that separates clean tie-ins from lumps.

Run these on flat plate first, then repeat them horizontal, vertical, and overhead. That progression mirrors how AWS certification tests are structured by process, material, and position, so flat-plate hours deposit skill you will eventually be tested on.

Dialing In Your Machine: Settings, Wire Speed, and Gas Flow

Beginners often treat the front panel of a welder like a safe combination: turn dials randomly until something works. It is not that mysterious. Voltage, amperage, wire feed speed, and gas flow are the four variables that decide whether your bead ties in or sits on top of the plate. The manufacturer’s chart under the lid of your machine gives you a starting window, never a final answer. The real setting is the one you verify with test beads on scrap before you touch anything structural.

Amperage and Wire Feed Speed

For stick welding on mild steel, a common 1/8-inch rod such as a 7018 is typically started in a broad mid-range around 90–120 amps, then adjusted by reading bead appearance. Go too low and the rod stubs, sticks, and leaves a tall, narrow lump. Go too high and the puddle gets wide and shallow while the flux boils off too fast. Move in small steps of about 5–10 amps and run a fresh bead each time. If you are still deciding which rod to buy, our all position welding rod guide covers how electrode choice changes with joint position.

For MIG on mild steel, a common beginner baseline is roughly 1 inch of wire feed speed per 10 amps of machine output. So a machine set to 180 amps of output starts near 180 on the wire feed dial (usually labeled in inches per minute). Then you tune by ear: a good short-circuit MIG arc sounds like frying bacon — a steady, soft sizzle. Popping and screeching mean the wire is stubbing into cold metal, which usually points to feed speed too high or voltage too low. A smooth hum with lots of spatter and a wide puddle means the opposite.

Shielding Gas Flow: More Is Not Better

Shielding gas flow for MIG on mild steel is commonly set around 20–25 CFH with a 75/25 argon-CO2 mix. That mix is cheap, stable, and forgiving on short-circuit settings. Excessive flow can actually pull atmosphere into the puddle, the same turbulence problem you get from a torn liner or a drafty garage door. Purge the line for a couple of seconds before striking the arc, keep the nozzle clean, and shield the work from wind — outdoors, even a light breeze strips your coverage and leaves wormhole porosity.

Gas choice shifts with material. Aluminum, for example, runs on 100% argon and demands cleaner settings and prep, which our aluminum MIG welding guide walks through in detail.

Polarity: DCEP vs DCEN, Made Simple

Polarity is the direction of current flow, and getting it wrong is one of the most common causes of weak, spattery beginner welds. Short-circuit MIG on thin steel typically runs DCEP (electrode positive), which gives deeper penetration and a stable arc. Many flux-core wires run DCEN (electrode negative) instead, because the wire itself carries less heat and the flux does the work. Some gas-shielded flux-core wires are the reverse, so read the specification printed on the spool before you connect the leads. If your welds are gloriously spattery and weak despite good technique, check polarity first — it is a two-minute fix. Aluminum flux-core wire has its own quirks worth reading about in our aluminum flux core welding breakdown.

Reading Your Own Weld: Too Hot or Too Cold

What you see and hear	Likely cause	Adjustment
Wide, flat, shallow bead with heavy spatter	Too hot: voltage or amperage too high	Drop one step, slow your observation, not your travel
Tall, narrow, ropey bead; wire stubbing; harsh crackle	Too cold: not enough heat or feed	Raise amperage or wire feed slightly
Melt-through holes on thin stock	Heat too high for material thickness	Lower settings, shorten welds, use stitch technique
Porosity, wormholes, surface pinholes	Dirty metal, wrong gas flow, or too much flow	Grind clean, set 20–25 CFH, check for drafts
Arc wandering, inconsistent sound	Arc length too long or unstable body position	Shorten arc, brace your hand, steady the torch

Run three test beads per setting change and write the numbers on the scrap with soapstone. One session of that methodical loop teaches you more than an afternoon of guessing, and it builds the habit of confirming every setting before the weld actually matters.

Common Beginner Mistakes and How to Fix Each One

Here is the good news about bad welds: they are almost never mysterious. A lumpy, spattery, porous seam usually traces back to a short list of causes, and once you can name the cause, the fix is usually one variable away. Learning to read a defect is a skill just like running a bead, and this is the troubleshooting page to revisit after every practice session.

Defect or error	What you see	Usual cause	The fix
Porosity (pinholes)	Craters or holes in and on the bead	Contaminated base metal, wind blowing gas away, flow too high or too low, dirty contact tip	Clean and dry the metal, check the cup and tip, rerun at 20–25 CFH, shield the area from drafts
Undercut	A groove melted into the base metal along the top edge	Amps too high, travel too slow at the toes, wrong work angle	Drop the heat slightly, speed up or weave briefly at the edges, angle the arc toward the top edge
Lack of fusion / cold lap	Bead sitting on top of the metal, not tied in	Travel too fast, arc too long, not enough heat for thickness	Slow down, shorten the arc, raise amperage, and push the puddle into the joint root
Excessive spatter	Balls of metal stuck everywhere	Wire speed too high, voltage too low, long arc, wrong polarity	Balance heat and wire speed, shorten the arc, verify polarity
Burn-through	Holes or sagging on thin metal	Too much heat, dwell in one spot, poor fit-up gap	Reduce heat, keep moving, stitch or pause-weld, clamp the gap tight
Weak or wandering arc	Arc stutters, wanders, or pops	Loose ground clamp, rusty ground point, long cable runs	Clamp to clean bare metal close to the joint
Bad stops and starts	Craters, lumps, cold starts	Restarting on top of the bead without overlap	Start slightly ahead, drag back into the crater, then continue

Porosity Is Almost Always a Shielding Problem

New welders tend to blame their hand when they see pinholes, but porosity is nearly always about the shielding envelope around the puddle. Gas-shielded processes need clean, dry metal and undisturbed flow. Mill scale, oil, paint, cutting fluid, and even condensed moisture on cold steel will outgas under the arc and boil straight into the weld. OSHA is blunt about this: welding, cutting, and brazing surfaces should be cleaned of coatings such as paint and solvent residue, because burning them can create toxic exposure beyond the normal welding fume (OSHA welding hazards guidance). The detailed requirement sits in the general industry welding standard, which requires surfaces to be free of hazardous coatings before hot work begins (29 CFR 1910.252). Aluminum is less forgiving still, since the oxide layer and any cutting oils will contaminate the puddle; see Aluminum Cleaner for Welding: How to Prep Aluminum Right for a proper cleaning sequence.

Gas flow is the other half. Too little, and atmospheric air leaks in; too much, and turbulence actually pulls air into the puddle. Most small MIG setups settle around 20 to 25 CFH. Weld outdoors or near an open garage door and a light breeze will strip your shielding gas away faster than you can chase it. Flux-core or stick is the sensible answer in a drafty driveway, which is one reason Advantages of Stick Welding: Why SMAW Still Wins remains relevant even in a MIG-dominated era.

Undercut, Cold Lap, and the Heat Conversation

Undercut and cold lap are opposite ends of the same dial. Undercut appears when you put too much heat into the joint edges and linger there, typically along the top edge of a fillet where the arc naturally points. Cold lap, where the bead sits on the plate like a caterpillar instead of biting in, happens when you move too fast, hold the arc too long, or run too cold for the material thickness. In both cases the corrective move is small: adjust one variable, run a test bead, and look again.

Work angle matters more than most beginners expect. In a fillet joint, pointing the arc squarely at the corner drives heat into the top edge and creates undercut; splitting the arc evenly between the two members evens out the profile. If you are still getting comfortable with angles, a single session of practice from All Position Welding Rod Guide: Types, Uses & Tips builds muscle memory faster than any amount of reading.

The Habits Behind the Defects

Several of the worst beginner problems are not weld defects at all; they are setup habits. A ground clamp clipped to paint, plating, or a rusty corner forces the current to find another path, and the arc pays for it with instability. Clean the ground point or move the clamp closer to the joint. Dirty base metal is the same story: five minutes with a flap disc, a wire brush dedicated to stainless or aluminum, and a solvent wipe prevents more defects than any technique change.

Restarts deserve their own mention because they fail constantly. Each stop leaves a crater, and crater cracks often start exactly there. When you restart, land the arc just ahead of the crater, drag it back until the puddle fills the divot, then move forward. The same discipline applies when you finish a bead: taper the heat or fill the crater rather than snapping off in place.

One safety habit fits naturally with defect prevention: hot metal looks exactly like cold metal. OSHA requires that after welding, the welder either mark hot metal or provide another effective warning to other workers (29 CFR 1910.252). Grabbing a fresh bead with a gloved hand is a rite of passage nobody needs; chalk-mark your workpieces and let them cool.

Work through the list in order: clean metal, solid ground, correct heat, steady arc, deliberate restart. Most of what looks like a skill gap is really a setup gap, and setup gaps are the cheapest problems in welding to fix.

The fragment has issues: it uses links to weldzen.com instead of weldgallery.com internal links, external link domains weird (“aluminum MIG welding guide” at weldzen.com — probably should be weldgallery internal). But instructions say “keeping the same heading, the same facts, and all of its links.” So I should keep the links.

Also note there’s escaped quotes in the fragment (`style=\”…\”`) — in the provided prompt it’s escaped because of JSON. Actually the output should use normal quotes.

Word count must be 560–840. Current fragment is roughly ~800 words? Let me estimate. Probably around 830. I should trim and tighten, keep all links, keep facts. Let me rewrite cleanly, concise, in range ~700-780 words.

Links to keep:

2. https://weldzen.com/aluminum-mig-welding-guide/

Also references “Section 8” — keep? It’s a cross-reference; fine to keep but maybe reword. Keep same facts. I’ll keep it but it’s a bit odd. I’ll say “the defects covered earlier in this guide.” Hmm, “same facts” — the fact is defects appear here. Fine.

Write with heading, h3s, lists, two callouts, table maybe for the 30-day overview (adds useful detail, but word count). Let me aim ~760 words.

Week 1 h3 (~7): “Week 1: The Flat Bead (Days 1–7)” ~7
Intro: “Your only goal this week is a stable, consistent arc on flat plate. No joints. No tricks. Just beads on a board.” ~21
Bullets:
Days 1–2: “Set your machine to the suggested range from the chart, clamp a piece of clean mild steel flat, and run beads at the recommended stick-out. Aim for beads about four inches long. Don’t worry how they look. Focus on a steady frying sound; if it crackles and pops unevenly, your travel speed or stick-out is drifting.” ~57
Days 3–4: “Stringer beads — straight passes with minimal side-to-side motion. Grade yourself on consistent width from start to finish.” ~18
Days 5–7: “Add a small weave, then compare it to a stringer. Most beginners weave far too wide; keep it narrower than about three electrode diameters.” ~25
Closing: “Practice economically: a bundle of 6013 rods and an angle grinder to clean and reset your plate will carry you through the week for a few dollars. On a MIG setup, run short welds and move to a fresh section of plate rather than long, sloppy passes.” ~46

Week 2 h3 ~7: “Week 2: T-Joints and Lap Joints (Days 8–14)”
Intro: “Now you introduce real joint geometry. Fillet welds in T-joints teach work angle and travel angle in a way flat beads never can.” ~24
Bullets:
“Run T-joints on coupon after coupon, aiming the arc equally at both members so neither side melts away first.” ~20
“Follow with lap joints, where your travel angle flattens and the puddle wets into the top edge of the overlapping plate.” ~21
“End each session by cutting the bead off and grinding the coupon flat for another run.” ~15
Then: “This is also the week to learn how filler choice changes the exercise. If you plan to branch into aluminum, our guide to aluminum MIG welding is worth reading now, because it shows how much narrower the margin for error gets once you leave mild steel.” ~44

Week 3 h3 ~8
Intro: “Butt joints are where beginners discover what a root pass actually is. Gap your plates, tack them, run a root bead, then cap over it.” ~24
Bullets:
“Start with a tight root — 1/16 inch gap or less for beginners — and tie both edges together without burning through.” ~22
“Run a second capping pass and check profile: a good cap sits slightly convex and blends smoothly into both plate edges.” ~22
“Almost every defect covered earlier in this guide will show up here. That’s normal. When something goes wrong, diagnose before you re-weld.” ~25

Week 4 h3 ~8
Intro: “Vertical-up, horizontal, and overhead. Gravity now fights you.” ~7
Bullets:
“Run vertical-up fillets on T-joints, slower and at lower current than you’d use flat.” ~15
“Try overhead only after you can hold a puddle vertically. Expect spatter, so protect your setup and yourself.” ~18
“Finish with a mixed-session test: one coupon flat, one vertical, one horizontal, back to back. That’s how certification tests are structured.” ~22

Evaluate h3 ~5
“Every weld gets a three-part grade:” ~6
Ordered list:
“Visual: consistent width, no porosity, no undercut, smooth tie-in at the toes.” ~12
“Break test: bend a practice bead off the plate and inspect the root. One break test teaches more than ten visual inspections.” ~21
“Process notes: write down settings, angles, and travel speed before you strike the arc, then note what happened. Cheap composition notebooks survive shop conditions better than phones.” ~28
Then: “Photograph or film every session. Phone video of your travel angle catches errors you can’t feel in the moment, and comparing week one footage to week four is the fastest confidence boost in the trade.” ~35

Instruction h3 ~6
“If you hit a wall — persistent undercut, inconsistent arcs, or out-of-position work that refuses to behave — book a few hours with a local instructor instead of burning another hundred pounds of consumables. For context on structured paths, AWS-endorsed workforce data shows welding certificate programs typically run 6 to 18 months, with associate degrees around two years. Aluminium welding course programs are a good example of what structured training covers. Apprenticeships combine paid on-the-job training with classroom theory, and employers consistently report stronger retention when mentorship is built into the program.” ~90

Short Note callout ~45:
“You don’t have to choose between self-teaching and formal training. Many of today’s best welders started as hobbyists, practiced deliberately for a few months, then used that base to test for certification and walk into better-paying work.” ~37

+37=871 — over 840. Need to trim ~40-60 words for safety. Target ~790.

Trim: remove table? Keeping table adds value but costs 39. Hmm. Better trim elsewhere. Let me trim the instruction paragraph (~90 → 75) and para 1 (56 → 45), and shorten some bullets.

Trim para 1 to: “Improving at welding isn’t about welding more. It’s about welding with a plan. Someone who burns rod for six months often improves less than someone who practices deliberately for eight weeks. Here’s a 30-day routine that takes you from a shaky first arc to real joints out of position without wasting a fortune on scrap.” — removed “structured” and “structured”? Count: ~53.

Actually let me just reduce a few items:
– Remove “Practice economically…” sentence partially: keep grinder fact. “Practice economically: a bundle of 6013 rods and an angle grinder to clean and reset your plate will carry you through the week for a few dollars. On MIG, run short welds and move to a fresh section of plate.” (~40)
– Days 1–2 trim to ~48.
– Instruction paragraph trim to ~78.
– Short note keep 37.

New total: 871 – 6 (para1) – 6 (economically) – 9 (days1-2) – 12 (instruction) = 838. Still tight. Trim more: drop the table? No — instead trim the visual list and some h3 intros.

Alternatively drop table and add nothing — total would be ~799. Safer. But table is nice… The requirement is 560–840, so 838 is within but risky if my count is off. Let’s remove the table and be around 800. Actually table also gives scannability. Hmm, I could shorten the table to 3 columns → keep. Let’s instead cut a different chunk: remove the “Photograph or film” paragraph? It’s useful.

Alternative: drop table (~39) and keep everything else trimmed → ~799. Good, safe and still detailed. But a table makes it richer… I’ll keep the table but trim aggressively elsewhere to ~810.

Let me settle: keep table, and cut:
– para1 → 48 (cut 8)
– Days 1-2 → 48 (cut 9)
– Economically → 38 (cut 8)
– Week 2 filler sentence → 38 (cut 6)
– Instruction → 75 (cut 15)
– Short note → 33 (cut 4)
Total cuts ~50 → 821. Still a bit high. Also cut break test list item by 5, process notes by 6, visual by 2 → 808.

Fine, ~800-810. My counting is approximate anyway. Let’s write final and recount roughly by summing my estimates for the final version.

A 30-Day Beginner Practice Plan That Actually Builds Skill

Improving at welding isn’t about welding more. It’s about welding with a plan. Someone who burns rod for six months often improves less than someone who practices deliberately for eight weeks. Here’s a 30-day routine that takes you from a shaky first arc to real joints out of position, without wasting a fortune on scrap.

Week	Focus	Goal
1	Flat beads on plate	Stable, consistent arc
2	T-joints and lap joints	Work angle and travel angle
3	Butt joints and root passes	Tie both edges without burn-through
4	Out-of-position work	Control gravity

Week 1: The Flat Bead (Days 1–7)

Your only goal this week is a stable, consistent arc on flat plate. No joints. No tricks. Just beads on a board.

• Days 1–2: Set your machine to the suggested range from the chart, clamp clean mild steel flat, and run beads at the recommended stick-out. Aim for beads about four inches long. Don’t worry how they look. Focus on a steady frying sound; if it crackles and pops unevenly, your travel speed or stick-out is drifting.
• Days 3–4: Stringer beads — straight passes with minimal side-to-side motion. Grade yourself on consistent width from start to finish.
• Days 5–7: Add a small weave, then compare it to a stringer. Most beginners weave far too wide; keep it narrower than about three electrode diameters.

Practice economically: a bundle of 6013 rods and an angle grinder to clean and reset your plate will carry you through the week for a few dollars. On MIG, run short welds and move to a fresh section of plate.

Week 2: T-Joints and Lap Joints (Days 8–14)

Now you introduce real joint geometry. Fillet welds in T-joints teach work angle and travel angle in a way flat beads never can.

• Run T-joints on coupon after coupon, aiming the arc equally at both members so neither side melts away first.
• Follow with lap joints, where your travel angle flattens and the puddle wets into the top edge of the overlapping plate.
• End each session by cutting the bead off and grinding the coupon flat for another run.

This is also the week to learn how filler choice changes the exercise. If you plan to branch into aluminum, our guide to aluminum MIG welding is worth reading now, because it shows how much narrower the margin for error gets once you leave mild steel.

Week 3: Butt Joints and Root Passes (Days 15–21)

Butt joints are where beginners discover what a root pass actually is. Gap your plates, tack them, run a root bead, then cap over it.

• Start with a tight root — 1/16 inch gap or less for beginners — and tie both edges together without burning through.
• Run a second capping pass and check profile: a good cap sits slightly convex and blends smoothly into both plate edges.
• Almost every defect covered earlier in this guide will show up here. That’s normal. When something goes wrong, diagnose before you re-weld.

Week 4: Out of Position Work (Days 22–30)

Vertical-up, horizontal, and overhead. Gravity now fights you.

• Run vertical-up fillets on T-joints, slower and at lower current than you’d use flat.
• Try overhead only after you can hold a puddle vertically. Expect spatter, so protect your setup and yourself.
• Finish with a mixed-session test: one coupon flat, one vertical, one horizontal, back to back. That’s how certification tests are structured.

How to Evaluate Yourself Honestly

Every weld gets a three-part grade:

1. Visual: consistent width, no porosity, no undercut, smooth tie-in at the toes.
2. Break test: bend a practice bead off the plate and inspect the root. One break test teaches more than ten visual inspections.
3. Process notes: write down settings, angles, and travel speed before you strike the arc, then note what happened. Composition notebooks survive shop conditions better than phones.

Film every session. Phone video of your travel angle catches errors you can’t feel in the moment, and comparing week one footage to week four is the fastest confidence boost in the trade.

When It’s Time to Seek Real Instruction

If you hit a wall — persistent undercut, inconsistent arcs, or out-of-position work that refuses to behave — book a few hours with a local instructor instead of burning another hundred pounds of consumables. For context on structured paths, AWS-endorsed workforce data shows welding certificate programs typically run 6 to 18 months, with associate degrees around two years. Aluminium welding course programs are a good example of what structured training covers. Apprenticeships combine paid on-the-job training with classroom theory, and employers consistently report stronger retention when mentorship is built in.

Getting Certified and Turning Skill Into Opportunity (Conclusion)

Thirty days of disciplined practice will take you from lumpy beads to something you would not be embarrassed to show a friend. It will not, by itself, get you hired. The gap between “I can weld” and “I can prove I can weld” is exactly what certification fills, and it is worth understanding early whether you plan to weld for fun or for a paycheck.

How AWS Certification Actually Works

The most useful thing to know about the American Welding Society’s Certified Welder program is that it is strictly performance-based. No classroom course, no textbook exam, no prerequisite work history. You show up, you weld, and your work is judged.

Concretely, the process looks like this:

1. You select a process, position, and material thickness you want to be tested on.
2. You go to an AWS Accredited Test Facility — a shop or testing center authorized to administer the test.
3. You weld a test coupon to a qualified Welding Procedure Specification (WPS), the written recipe specifying process, filler metal, polarity, heat input, and technique.
4. Your weld is evaluated against the acceptance criteria of the applicable code: visual inspection first, then bend or radiographic testing depending on the code.

Which code applies depends on the work. Structural steel welders most often test under AWS D1.1, while pipeline welders typically test under API 1104, as outlined in AWS career resources.

What It Costs — and What It Returns

AWS reports that entry-level Certified Welder certification typically ranges from a few hundred dollars to around a thousand, inclusive of testing fees and materials. Advanced credentials sit in a different tier: a Certified Welding Inspector qualification can run into several thousand dollars, and rightly so, since it carries inspection authority over other people’s work.

Credential	Typical Cost	Who It’s For
Certified Welder (entry process/position)	~$300–$1,000	Anyone entering fabrication, structural, or shop work
Additional process/position tests	Similar range per test	Welders broadening their scope
Certified Welding Inspector	Several thousand	Experienced welders moving into QA/QC

Those numbers look steep until you weigh them against earning data. Certified welders consistently out-earn uncertified ones, and certification is the standard gate employers use for structural, pipeline, and pressure work. If cost is the obstacle, the AWS Foundation awards roughly $2.7 million in scholarship funds annually and supports more than 1,600 students, with about 25% of scholarships going to female welding students. Trade school and certificate programs can also be a legitimate on-ramp; this aluminium welding course breakdown shows what a structured curriculum typically covers and what it costs.

Staying Certified: The Six-Month Rule

Certification is not a certificate you frame and forget. Your card remains valid only as long as you maintain continuity, which means submitting maintenance documentation every six months confirming that you have continued to use the certified process. Miss the paperwork and you retest. Build the habit of logging your work as you go rather than scrambling at the deadline.

The Path, Recapped

Look back at how far the last few weeks have actually moved you:

• You picked a forgiving first process instead of fighting an unforgiving one, and you know why — the same reasoning explains why stick welding still wins in so many real-world conditions.
• You built a workspace that manages fire, fume, and flash before the first arc ever strikes, and you wear real PPE every time.
• You learned to set the machine from the chart and then correct it from the puddle.
• You drilled arc length, travel speed, and work angle until your hands stopped arguing with your eyes.
• You read your own defects — porosity, undercut, cold lap — as diagnosis puzzles instead of failures.
• You ran a structured month of practice and watched your beads flatten out week by week.

That sequence is the entire craft in miniature. Certification simply puts a recognized stamp on it. It also does not have to stop at one: a welder who can hold a steady puddle in flat, horizontal, and all-position work becomes the person shops fight over. From there the field widens fast — aerospace, marine, pressure vessel, and inspection paths all open up, including specialized routes like an aerospace welding school for welders who want to work to tighter tolerances.

A Final Word

Nobody welds well because they were born with steady hands. They weld well because they burned a lot of cheap plate while paying attention to arc length, settings, and prep. The first bead never looks like the picture on the internet. The hundredth looks a lot closer, and the five-hundredth looks like someone who does this for a living — because by then, you do.

Strike the arc, keep it short, keep it consistent, and keep your hood down. The skill follows the practice, and the opportunity follows the skill.

Frequently Asked Questions

What welding process should a beginner learn first?

Gas metal arc welding (MIG/GMAW) on mild steel is the most forgiving starting point because the machine regulates much of the heat and filler delivery. Flux-core is a solid alternative if you cannot run shielding gas or mainly weld outdoors. Stick welding builds excellent fundamentals and works anywhere, and TIG is best saved until your hand control is developed.

How much does it cost to start welding as a beginner?

A functional starter setup — an entry-level MIG or flux-core machine, helmet, jacket, gloves, clamps, grinder, and consumables — realistically runs several hundred to low thousands of dollars depending on machine capability and whether you add a shielding gas cylinder. Spend on safety gear and a reliable ground clamp first; cosmetic upgrades can wait.

Do I need a certification to start welding?

No. AWS’s Certified Welder program is performance-based with no prerequisite courses, certifications, or minimum experience required — if you can make the weld, you can test for it. Certification becomes important when you want to weld on code work such as structural steel or pipeline, since employers must verify your qualifications.

Is welding fume dangerous for hobbyists working in a garage?

Yes, fume is a real health hazard even at hobby scale. OSHA requires mechanical ventilation when welding in spaces under 10,000 cubic feet per welder or rooms with ceilings under 16 feet, at a minimum of 2,000 CFM per welder. At home, keep doors and windows open, position yourself upwind of the plume, use a portable fume extractor when possible, and never weld galvanized, plated, or painted metal without extra caution.

Why is my weld full of holes (porosity)?

Porosity almost always comes from contaminated shielding rather than bad hand skill: dirty or oily base metal, paint or primer burning off, wind blowing your gas away, wrong gas flow, a damaged contact tip, or leaking gas lines. Clean the metal back to bright steel, check your gas setup, and eliminate drafts before blaming your technique.

What amperage should I use for a 1/8-inch 7018 stick electrode?

Most beginners start somewhere around 90–120 amps for a 1/8-inch 7018 on mild steel, then adjust based on what the puddle tells you. If the rod keeps sticking or the bead is tall and narrow, increase amps slightly; if you are blowing through the plate or the bead is flat and wide, decrease them. Always dial in on scrap of the same thickness first.

How long does it take to get good at welding?

Most people can run a presentable bead within a few practice sessions and weld simple joints within a few weeks of regular practice. AWS notes that someone new to the trade may spend several months developing the skills needed to pass a qualification test. Consistent, deliberate practice on varied joints matters far more than total hours burned.

What shade should my welding helmet lens be?

A variable-shade auto-darkening helmet in roughly the shade 10–13 range covers most beginner stick, MIG, and flux-core work, letting you adjust as amperage changes. The arc’s ultraviolet radiation can damage eyes within seconds, so never strike an arc with a bare face or a fixed shade that is too light. Safety glasses should be worn under the helmet at all times.

Should I weld in an enclosed garage or outside?

Outdoors or in a wide-open shop is always better for fume dispersal. If you must weld indoors, treat OSHA’s thresholds as your guide: mechanical ventilation is needed in spaces under 10,000 cubic feet per welder or with ceilings under 16 feet, and confined spaces require much more rigorous controls. Never weld in a sealed garage with a car running — carbon monoxide and shielding gases can displace oxygen rapidly.
