Beginner Welding Rod Chart: How to Read It and Pick the Right Rod

You walk into the welding supply aisle with $40 and a cheap buzz-box welder at home, and the shelf is stacked with grey sticks labeled 6011, 6013, 7018, 3/32, 1/8, and numbers you were never taught. Pick the wrong one and you will burn holes in thin steel or weld a bead that snaps in half — which is exactly why the little electrode selection chart printed in every welding manual exists.

Why Every Beginner Needs a Welding Rod Chart Before Striking the First Arc

Picture the scene: it is Saturday morning, you have a trailer fender to patch and a borrowed buzz-box welder sitting on the garage floor. You buy a $12 pack of 1/8 in rods, clamp the ground, dial the machine to a number that “looks about right,” and strike an arc. The first pass gouges a molten hole straight through the sheet. You turn the heat down, and now the rod sticks to the metal like chewing gum, glowing cherry red until you wrench it free. Nothing you tried was random, but none of it was informed either. That is the gap a welding rod chart closes before you ever strike the first arc.

What a Welding Rod Chart Actually Is

A welding rod chart, more formally called an electrode selection chart, is the one-page table printed inside stick welding manuals, taped inside machine doors, and published by electrode makers. It answers four questions at once, which is why it is so much faster than guesswork:

• How thick is the metal you are about to weld, in fractions of an inch and gauge?
• Which electrode classification and diameter can actually fill that joint in the position you are in?
• What polarity does that rod want: AC, DCEP, or DCEN?
• What amperage window should the machine be set to for that combination?

In short, a good chart cross-references base metal thickness, weld position, electrode classification and diameter, and the recommended amperage range with polarity all on the same row. You find your plate thickness on the left, read across, and land on one or two rod diameters plus a heat range. Most rows begin with plate thickness in fractions of an inch and gauge, then narrow to the single rod size that can properly fill that joint, because the chart is not listing every rod that exists — only the ones that work for that specific job.

What Happens When You Ignore It

Amperage is not a preference; it is the difference between metallurgy and a mess. Set the machine too hot and the arc blows through the plate, leaving a hole you now have to fill with weld — a slow, ugly process that warps thin steel. Set it too cold and fusion never happens. Welding too cold on the 1/8 in (3.2 mm) E7018 setting designed for quarter-inch plate leaves a pile of undigested flux and a bead sitting on top of the metal instead of biting into it. That is cold lap, also called lack of fusion, and it is the kind of defect that looks fine from across the shop and fails under load.

Consider a typical beginner discovery: you first burn 1/8 in E6013 at roughly 100–120 A on 3/16 in plate and get a bead you are genuinely proud of. Then you take the same rod, the same heat, and touch it to 16-gauge sheet — and it melts straight through in seconds. The rod did not change; the thickness did. That single realization, that every rod has a thickness window rather than a universal setting, is what the chart is trying to teach you before you learn it the expensive way. In the worst case, guessing produces cracked welds, because under-fused or over-thinned joints cannot carry the load placed on them.

Who Publishes These Charts

Three groups publish them. The American Welding Society writes the specification — AWS A5.1 covers carbon steel electrodes for shielded metal arc welding — and its classification system is the backbone of every chart in circulation (American Welding Society). Electrode manufacturers such as Lincoln, ESAB, and Hobart print their own versions based on how their specific coatings behave. Machine manufacturers print abbreviated charts on the inside of the welder’s door, tuned to that model’s output. Where the numbers differ slightly between sources, they are usually reflecting real differences in rod chemistry, not errors.

What You Will Walk Away With

By the end of this guide you will be able to decode any rod box, choose diameter and classification for the plate in front of you, set an amperage window with confidence, and read your own bead to know whether the setting was right. You will also understand where the chart stops being useful — unusual alloys, out-of-position work, and nonferrous metal — and where related processes pick up the slack, as covered in our guide to the advantages of stick welding and why SMAW still holds its ground on job sites.

The chart will not make you a welder. It removes the guesswork so that your practice time goes into arc control, travel speed, and puddle reading instead of chasing avoidable defects. That is a worthwhile trade for a sheet of paper you can read in ten seconds.

How to Read the Code on the Rod Box: The AWS Classification Explained

Pick up any stick electrode box and you will see the same short code stamped in bold: E6013, E7018, E6011. That code is not a part number invented by the manufacturer. It is a standardized classification, and once you can read it, you can decode roughly 80 percent of what a rod will do before you ever strike an arc. The code answers four questions in order: what kind of rod it is, how strong the weld metal will be, which positions you can weld in, and what coating and current it runs on.

Digit by Digit: What Each Number Means

The classification comes from the American Welding Society’s specification for carbon steel electrodes, AWS A5.1, so the same four characters appear on the box, stamped on the bare end of the rod itself, and printed in the electrode selection chart in your machine’s manual. They all mean exactly the same thing.

• Leading “E”: stands for arc welding electrode. It tells you this is a stick rod, not a wire or a filler metal for TIG.
• The next two or three digits: give the minimum tensile strength of the deposited weld metal in thousands of pounds per square inch. So the “70” in E7018 means 70,000 psi, roughly 483 MPa. The “60” in E6013 and E6011 means 60,000 psi, about 414 MPa.
• The position digit: tells you where you may weld with it. A “1” means all positions: flat, horizontal, vertical, and overhead. A “2” means flat and horizontal only.
• The final digit: encodes the flux coating type and the usable current. A “1” is a high-cellulose coating, an “8” is a low-hydrogen iron-powder coating, and a “3” is a rutile titanium dioxide coating.

Work through E6013 as a first example: E = electrode, 60 = 60,000 psi minimum tensile strength, 1 = usable in all positions, 3 = rutile coating that runs on AC or DC electrode positive. Now E7018: E = electrode, 70 = 70,000 psi, 1 = all positions, 8 = low-hydrogen coating that runs on AC or DCEP.

The Common Beginner Rods at a Glance

Rod	Tensile	Position	Coating / Current	Typical Use
E6010	60,000 psi	All	High cellulose, DCEN only	Deep penetration on dirty or rooted steel, pipe root passes
E6011	60,000 psi	All	High cellulose, AC or DC	Rusty, painted, greasy farm steel on an AC buzz-box
E6013	60,000 psi	All	Rutile, AC or DC	Thin sheet, clean mild steel, learning arc control
E7018	70,000 psi	All	Low hydrogen, AC or DCEP	Structural work, strong smooth beads, critical joints
E7024	70,000 psi	Flat & horizontal	Iron powder, AC or DC	Fast, heavy fillet welds in the flat position

The position digit is where beginners get burned. An E7024 rod is a lovely fast-fill rod, but its “2” means it belongs flat and horizontal only, so trying to run it overhead will dump molten metal on you. If your work leaves the flat position, restrict yourself to rods ending in “1”, which is exactly what our All Position Welding Rod Guide covers in more depth.

Coating chemistry matters just as much as numbers. The “1” coating on E6011 and E6010 is loaded with cellulose, which breaks down into a forceful, deep-penetrating arc that blasts through rust and paint but produces noticeably more smoke and fume. The “8” coating on E7018 is low-hydrogen: quieter, cleaner, and stronger, but moisture-sensitive. Everything outside plain carbon steel follows the same logic of matching the classification to the metal, as explained in Alloy Steel Welding Electrodes: Selection, Use & Safety.

One practical detail: because the last digit only partially describes current, check the box for exact polarity. E6010 is DC-only, while E6011 adds AC capability for cheaper machines. E6013 and E7018 run on AC or DC, though E7018 gives its best results on DCEP. Once the code makes sense, the chart in the next section stops being a wall of numbers and becomes a set of instructions you can actually follow.

The Beginner Welding Rod Chart: Diameter, Thickness, Amperage and Polarity

Here is the chart the rest of this article points back to. Every row is a rod you can buy off a supply shelf, and every number is a realistic starting window for mild carbon steel on a basic stick machine. Match the diameter to your metal and set the machine mid-band.

Electrode	Diameter	Amperage window	Suits this material	Polarity
E6010	3/32 in	40–75 A	Sheet and light plate; root passes	DCEP
E6011	3/32 in	40–80 A	Sheet; thin rusty or painted steel	AC or DCEP
E6013	3/32 in	40–90 A	Sheet and light plate; first-ever welds	AC, DCEP or DCEN
E7018	3/32 in	60–110 A	Thin-to-light plate; root passes	AC or DCEP
E6010	1/8 in	75–125 A	1/8–3/16 in plate; open-root joints	DCEP
E6011	1/8 in	80–130 A	1/8–3/16 in; dirty or rusty farm steel	AC or DCEP
E6013	1/8 in	80–130 A	16- to 8-gauge work (about 1/16–3/16 in)	AC, DCEP or DCEN
E7018	1/8 in	110–165 A	1/8–3/16 in plate; structural joints	AC or DCEP
E7024	1/8 in	110–165 A	Light plate, flat fillet welds	AC, DCEP or DCEN
E6010	5/32 in	110–170 A	3/16–1/4 in plate; deep-penetration passes	DCEP
E6011	5/32 in	110–165 A	3/16–1/4 in; repair on imperfect steel	AC or DCEP
E6013	5/32 in	100–160 A	3/16–1/4 in plate	AC, DCEP or DCEN
E7018	5/32 in	150–220 A	3/16–3/8 in structural steel	AC or DCEP
E7024	5/32 in	165–230 A	3/16–1/4 in, flat and horizontal fillets	AC, DCEP or DCEN
E6010	3/16 in	140–220 A	1/4 in and heavier	DCEP
E6011	3/16 in	150–225 A	1/4 in and heavier	AC or DCEP
E6013	3/16 in	160–230 A	1/4 in and heavier	AC, DCEP or DCEN
E7018	3/16 in	200–275 A	1/4 in and heavier, heavy structural	AC or DCEP
E7024	3/16 in	230–300 A	1/4 in and heavier, flat horizontal fillets	AC, DCEP or DCEN

These are typical shop values, not gospel. Exact ranges come from the electrode manufacturer and sit inside the AWS filler metal specification, so check the A5.1 data sheet and the chart on the rod carton before committing a setting.

The One-Amp-Per-Thou Rule

Behind almost every number in that table is a shortcut: on mild steel with DC, a rod runs at roughly 1 amp per 0.001 in of diameter. A 1/8 in rod is 0.125 in, so it centers near 125 A. A 3/32 in rod is 0.093 in, near 90 A. A 5/32 in rod is 0.156 in, near 155 A, and a 3/16 in rod is 0.188 in, near 190 A.

Notice how cleanly those centers sit inside the table bands. The rule ignores classification: it is a heat-per-diameter estimate, while coating and chemistry decide how that heat lands. An E7018 at 125 A behaves nothing like an E6013 at 125 A on the same dial.

Sizing Rod Diameter to Plate Thickness

Pick a rod diameter close to the thickest part of the joint, then work down. Eighth-inch rod handles 1/8 in plate and stretches to 3/16 in. Anything thinner than about 1/8 in wants 3/32 in or smaller, because a big rod dumps heat faster than thin steel can spread and you burn through. Above 3/16 in, step up to 5/32 in or 3/16 in rods for the heat and deposition rate full fusion needs.

One catch beginners learn the hard way: a cheap 120 V buzz-box usually tops out near 140–160 A, so the 3/16 in E7018 and E7024 rows are aspirational unless you own a 230 V machine. Read the chart, then read your welder’s nameplate.

When You Only Own One Rod Size

Most beginners can only afford a box or two, so buy 1/8 in rod: it covers the widest range. A 1/8 in E6013 works from 16 gauge through 3/16 in plate, and a 1/8 in E7018 covers 1/8 in through 3/16 in with real structural strength, right where the chart’s window overlaps your machine.

Then adjust the dial instead of the rod: drop toward the bottom of the band for thinner metal with a shorter arc and faster travel, push toward the top for thicker metal with a longer arc. With one rod, thickness control comes from amps and travel speed. For out-of-position or heavier work, our all position welding rod guide covers which rods hold up when you cannot stay flat.

Rod-by-Rod Profiles: E6010, E6011, E6013, E7018 and E7024

The beginner welding rod chart tells you what size rod to run and how hot to run it, but it cannot tell you how the rod will behave in your hand. Some coatings dig like a plasma torch, some hide a sloppy bead under a cushion of slag, and some refuse to run unless the steel is spotless. Here is what each one actually does.

E6010: Forceful Arc, Deep Dig, No Forgiveness

E6010 has a thick cellulose coating that burns aggressively, producing a forceful, spray-like arc with deep, narrow penetration. That is why it is the standard root-pass rod for pipe: it burns through root gaps and contamination and fuses the very bottom of the joint. On thin sheet it punches straight through, and an inconsistent arc length shows immediately as a lumpy, spattered bead. It runs on DC electrode positive (DCEP) only. Buy it when you need penetration on dirty or edged joints, but do not start here.

E6011: The Farm-Steel Repair Rod

E6011 is essentially E6010’s more practical sibling. The cellulose coating is blended with potassium, which stabilizes the arc and lets the rod run on alternating current. That single change matters enormously for a beginner, because most inexpensive buzz-box welders put out AC only. E6011 burns through rust, paint, mill scale and old weld beads better than almost any other rod, which makes it the right choice for a tractor implement, a gate hinge or a rusty trailer. It still penetrates deeply, so it can burn holes in thin steel, and the bead is not pretty by design.

E6013: The Rod That Teaches Arc Control

E6013 uses a rutile, or titanium dioxide, coating that produces a soft, stable arc with low spatter. The flux melts into an easy-to-remove slag blanket and leaves a smooth, slightly convex bead. Crucially, it forgives inconsistent arc length, the single biggest habit a new welder has to unlearn. It runs on AC, DCEP or DCEN, taking almost any polarity your machine offers, and it handles thin metal without the eagerness to blow through that E6010 and E6011 show. This is the rod to buy first and run for your first few pounds of practice beads.

E7018: The Low-Hydrogen Strength Rod

E7018 is a low-hydrogen electrode with an iron powder–lime coating. It delivers high-strength, ductile welds with very low spatter and a smooth profile, and it is the rod that builds structural habits: steady travel speed, tight arc, no weaving tricks. It wants cleaner base metal than E6013, it runs best on DC, and it must be stored dry. Moisture from humid air is driven into the weld pool as hydrogen, causing porosity and delayed cracking. Keep opened containers in a rod oven or sealed quiver, and re-bake exposed rods before trusting them structurally. Those expectations come from the AWS A5.1 classification published by the American Welding Society.

E7024: The Fast, Flat Production Rod

E7024 has a heavy iron powder coating that carries high current, lays a wide, fat bead and deposits metal fast. The slag lifts in a clean sheet with little cleanup. The catch is positional: it is essentially flat and horizontal-only, so its wide profile will not fit into tight fillets or out-of-position work. It excels at long bench runs and little else. Working beyond mild steel? Our alloy steel welding electrodes guide covers how classification changes with the base metal.

Rod	Coating	Penetration	Polarity	Best for
E6010	Cellulose	Deep, narrow	DCEP	Pipe roots, dirty edges
E6011	Cellulose + potassium	Deep, forceful	AC / DCEP	Rusty repair steel
E6013	Rutile	Moderate	AC / DCEP / DCEN	Thin metal, beginners
E7018	Low-hydrogen lime	Moderate to deep	DC (AC versions exist)	Structural work
E7024	Iron powder	Moderate	DC / AC	Flat production welding

Which Two or Three Rods Should You Buy First?

You do not need every box on the shelf. A sensible starter kit is one 5-lb pack each of E6013 and E7018 in 1/8 inch, plus a small pack of E6011 if your machine is AC-only or you expect rusty repair work. Learn on the E6013 until your beads look consistent, then switch to E7018 to learn cleanliness, storage and travel discipline. Add E6010 for pipe roots later, and pick up E7024 only for long flat runs.

Once you know what each rod is trying to do, the chart becomes a decision you make in seconds. For more on how position, polarity and coating interact across processes, see our all-position welding rod guide and why stick welding still holds its own against wire processes.

Dialing In the Machine: Amperage, Arc Length, Polarity and Heat Control

The chart hands you a number, but the machine has a dial that drifts, an extension lead that eats a few amps, and a duty cycle that sags when things get hot. Turning the printed band into a good bead is a translation job, and most of it happens through your eyes and ears once the arc is lit.

Start in the Middle of the Band, Then Nudge

If the chart calls for 110-130 A with a 1/8 in rod on quarter-inch plate, set 120 A and run your first bead on scrap of the same thickness, not on the project. Then change one thing at a time in 5 to 10 A steps. Big jumps blur the diagnosis: drop 20 A and you cannot tell whether the fix or the overshoot saved the weld. Watch the bead, not the dial.

What you see and hear	Diagnosis	What to change
Wide, flat bead, heavy spatter, hissing arc, burn-through on thinner plate	Too hot	Drop 10-15 A, or step down one rod diameter
Narrow, high-crowned bead, slag that refuses to lift, rod freezing when you pause	Too cold	Raise 10-15 A, slow your travel slightly
Even ripple, wetted toes, slag peeling off in one piece, sound like frying bacon	Close to right	Note the dial reading and keep it
Erratic arc that wanders or drops out	Arc too long or dirty metal	Tighten arc length, clean the plate

Arc Length and Travel Speed

The single fastest skill upgrade after reading the chart is holding a tight arc. A good target is roughly the diameter of the electrode: a 1/8 in rod rides about 1/8 in off the work, a 3/32 in rod a little closer. Stretch it out and you get a long, hissing arc that scatters spatter, lets atmospheric nitrogen attack the puddle, undercuts the toes and loses the flux’s shielding. Touch the work and the rod freezes to the plate, which is exactly what a too-cold setting feels like when you pause.

Travel speed works with arc length as a team. Move too fast and the bead stands tall with poor fusion at the toes; move too slow and heat soaks in, widening the puddle until thin steel blows through. A useful cue is to keep the puddle roughly as wide as the rod and let it wet out just past the rod diameter. Out of position, hold the arc a touch tighter, since gravity is already pulling the puddle the wrong way.

Polarity: AC, DCEP and DCEN

Polarity decides where the arc heat goes. Direct current electrode positive (DCEP) is the deep-penetration setting, driving roughly two-thirds of the arc heat into the work, and it is the default for root passes and thicker steel. DCEN shifts more heat into the electrode, so the rod melts off faster and deposits metal quicker with shallower penetration, which suits thin sheet and fast cover passes. Alternating current swings between the two, splitting the difference with a slightly softer arc that forgives dirty, rusty or painted surfaces.

This matters at checkout because many budget machines ship AC-only. An AC machine cannot run a DC-only electrode such as E6010, so an AC-capable E6011 or E6013 is the sensible first purchase until you own a DC output. Add DC and the door opens to E7018 low-hydrogen work, deeper penetration and quieter, more stable arcs. The polarity symbols stamped on the rod box and printed in the chart come from the same source: electrode classification and operating recommendations trace back to American Welding Society standards (aws.org), so box, end stamping and chart should always agree.

A Simple Dialing-In Routine

1. Set the machine to the middle of the chart’s band for your rod and thickness.
2. Strike an arc on scrap and hold a length-of-rod arc for three seconds.
3. Read the bead: flat and spattery means back off, crowned and sticky means add heat.
4. Fine-tune in 5-10 A steps until the slag lifts cleanly and the toes are wetted out.
5. Write the working setting on the box so the next session starts where this one finished.

With the setting locked in, the puddle behaves and the slag peels, freeing your attention for travel speed and rod angle. Our advantages of stick welding breakdown explains why that control makes stick so versatile, and an Airgas welding equipment guide compares AC-only, AC/DC and DC-only machines on price and capability.

Positions, Joint Types and Plate Thickness: Choosing Rods for the Work in Front of You

Every beginner chart is printed for flat work, but real projects rarely stay there. A trailer frame, a gate post, or an urgent repair can all put you in a position where gravity is fighting your puddle. Because of this, position, joint type, and plate thickness should be decided before you ever look at amperage.

The Four Positions and Gravity

Welders classify positions by a number and letter: 1F/1G (flat), 2F/2G (horizontal), 3F/3G (vertical), and 4F/4G (overhead). “F” means a fillet weld, while “G” means a groove weld.

• Flat: Gravity assists the puddle. This is where chart settings are the most accurate and where larger rods can run with ease.
• Horizontal: On a vertical wall or horizontal seam, the puddle wants to sag. A slight amperage drop and a steady travel speed are usually needed to combat this.
• Vertical: Welding up or down a seam changes the arc entirely. The direction you choose is often just as important as the rod you use.
• Overhead: With the puddle hanging above you, gravity is at its strongest. Everything here must be scaled down to stay in control.

The Position Digit Matters

The fourth digit of an AWS classification tells you exactly which of these positions a rod is qualified for. As defined by the American Welding Society in specifications such as AWS A5.1, a digit of “1” means the electrode is approved for flat, horizontal, vertical, and overhead welding. A digit of “2” restricts it to flat and horizontal fillet and butt welds only.

For beginners, E6010, E6011, E6013, and E7018 are all all-position (“1”) rods. The biggest exception is E7024, a downhand specialist that excels on flat and horizontal butt joints, but is entirely unsuited for overhead work.

Vertical-Up or Vertical-Down?

For structural or strength-based welds, vertical-up should be your default. Slowing your travel and pausing to tie into both walls of the joint allows for far better penetration control. This level of control is one of the reasons why stick welding still beats newer processes for certain repairs.

Vertical-down has its place, however. On thin sheet metal, its fast travel speed greatly reduces heat input and distortion. On thicker material, the arc points away from the joint as you travel, causing the puddle to freeze ahead of fusion and creating a high risk for lack of fusion. If using it, back off 5 to 10 amps from your flat setting, and always opt for vertical-up when strength is a priority.

Overhead: The Smaller Rod Rule

Overhead is almost always a scaling exercise. Most welders drop down to 3/32 inch rod, decrease amperage, hold a tighter arc, and travel quicker than they would flat. An all-position (“1”) rod is mandatory, with 3/32 inch E6011 or E7018 being the most common picks. If your puddle is sagging or dripping, resist the urge to add heat. The fix is almost always less heat, a smaller rod, and faster travel.

Joint Design and Plate Thickness

Before picking a diameter, assess the joint itself. Each design handles heat differently:

Joint	Puddle Behavior	Practical Approach
Butt (Groove)	Fuses full thickness between two edges	Great for multi-pass work. Downhand rods like E7024 can be used flat here.
Lap	Fuses an edge onto another plate	Use moderate heat and a slight drag angle to avoid burning through the top plate.
T-Joint (Fillet)	Wets two plates at 90 degrees	Focus on throat thickness, not leg size, to judge a strong weld.
Corner	Thin, exposed edges melt back extremely fast	Run less amperage than your flat-plate chart suggests to avoid blowthrough.

Once plate thickness exceeds roughly 1/4 inch, a bevel is often required. A single-V groove with a 60 to 90 degree included angle and a small root gap will allow a root pass to reach the bottom, with fill and cap passes building up the rest. Thick plates act as a heat sink as well, so it’s common to run a smaller rod for the root before stepping up for your fill passes.

A Quick Routine For Out-Of-Position Work

1. Name the position first. If it’s vertical or overhead, only an all-position (“1”) rod will qualify. If it’s flat or horizontal only, E7024 is an option.
2. Scale down. Step down one rod size and cut 5 to 10 amps from your flat setting.
3. Match to thickness. Use 3/32 inch for material under 1/8 inch, 1/8 inch for 1/8 to 1/4 inch, and bevel with multi-pass for anything over 1/4 inch.

Position doesn’t change the physics of the arc, it changes how much of the puddle you’re forced to fight. Read the joint before you read the chart.

Safety, Fumes and Rod Handling: The Rules That Protect Your Lungs and Your Work

A welding rod chart is a map of metal, diameter and amps. It will never tell you what is floating in the air once the arc is lit. Every recommendation in the chart quietly assumes the same thing: that you are striking that arc in a ventilated space, wearing real protection, and working on a job that has been cleared for hot work. Skip those assumptions and a $7 pack of rods can cost you far more than money.

What Is Actually in the Smoke: Ventilation and Respiratory Protection

Flux is a chemical coating, and it burns. The fume that rises off a stick arc is a mix of metal oxides from the electrode and base metal, flux combustion products, and gases such as ozone and nitrogen oxides. What comes off depends heavily on the rod family. Cellulose-coated electrodes like E6010 and E6011 run hot and deep, and they produce noticeably more smoke and fume than low-hydrogen rods such as E7018. The NIOSH welding safety topic page lists the main concerns welders face: metal fumes, welding fume constituents like manganese and nickel, and irritating gases.

The rules are not vague. OSHA standard 1926.353 requires ventilation general or local enough to keep airborne contaminant concentrations within permitted exposure limits, and it requires approved respiratory protection where ventilation alone cannot do the job. General industry welding has a parallel requirement under 1910.252. Practically, that means you weld outdoors or in a shop with real air exchange, not in a closed garage with the door half down.

Rod family	Examples	Fume and smoke tendency
Cellulose (fast-freeze)	E6010, E6011	Higher smoke, more visible fume, deeper penetration
Titanium oxide (rustic)	E6013	Moderate fume, easier on beginners outdoors
Low-hydrogen (basic)	E7018, E7024	Less smoke, but demands dry storage and cleaner base metal

The 30-Minute Fire Watch Rule

Spatter and hot slag travel farther than beginners expect, and they land in places you never checked. OSHA standard 1926.352(b) requires that a fire watch be maintained for at least 30 minutes after welding or cutting operations end, so smoldering material in wall cavities, insulation, sawdust or trash can be spotted and extinguished. Remove or protect all combustibles within a generous radius, keep an extinguisher at arm’s reach, and never weld or cut on a closed container, which can rupture from pressure build-up.

Arc Radiation, Proper PPE and Hexavalent Chromium

The arc produces ultraviolet light intense enough to burn skin like a sunburn and to inflame the cornea, the injury welders call arc eye. Minimum protection means an auto-darkening helmet with the right shade, safety glasses underneath with side shields, flame-resistant jacket and sleeves, and heavy leather gloves. No synthetics next to your skin, because they melt rather than char. Hearing protection and steel-toe boots round out the kit.

One hazard deserves special mention for beginners because it is invisible: hexavalent chromium, or Cr(VI). Welding stainless steel or chromium-bearing alloys generates it in the fume. OSHA’s hexavalent chromium standard, 1910.1026, sets a permissible exposure limit of 5 micrograms per cubic meter of air as an 8-hour time-weighted average, with exposure monitoring, written controls and respiratory protection requirements layered on top. Stick to mild steel while you learn, and read up before you branch into other metals, as covered in our guide to alloy steel welding electrodes.

Keeping Low-Hydrogen Rods Dry: Storage and Re-Baking E7018

E7018 is the rod that earns your structural trust, and the rod that punishes careless storage. Its basic coating absorbs moisture from humid air within hours of leaving the sealed package. Wet coating puts hydrogen into the weld puddle, which shows up as porosity, and worse, as delayed cracking hours after you finished. Keep opened boxes in their foil or in a sealed container, carry rods in a rod caddy during the job, and return unused E7018 for re-baking on the schedule and at the temperature the manufacturer specifies. Never re-bake rutile rods like E6013, and never leave low-hydrogen rods overnight on a damp shop bench. Sealed rod ovens are the professional standard, and a dry bucket with a gasketed lid is the honest beginner version. Supplies like caddies, ovens and PPE are easy to source through vendors such as those covered in our AllGas welding supply guide.

The pattern behind all of this is simple: the chart picks your rod, but safe practice keeps that rod from hurting you. Get the ventilation, the fire watch and the dry storage right, and the rest of the learning curve gets a lot more forgiving.

Common Beginner Mistakes and Troubleshooting: What Your Weld Is Trying to Tell You

A bad bead is not a verdict on your talent. It is a message. Spatter, pinholes, the crown down the middle of the weld: each one is the arc telling you what went wrong before the arc was ever struck. Almost every beginner failure traces back to three chart mistakes, and once you can name them, fixing the weld takes five minutes instead of an afternoon of frustration.

The Three Chart Mistakes Almost Every Beginner Makes

• Wrong rod for the metal. You grabbed the cheap, friendly E6013 and ran it over rust, paint and mill scale. Or you ran a low-hydrogen E7018 over dirty, heavily scaled steel: E7018’s coating protects the puddle but does not clean it, so the contamination stays trapped and comes back as porosity or a weak, slag-heavy bead. When the base metal is contaminated and you cannot prep it perfectly, E6011 is the forgiving choice, because its cellulose arc essentially burns the gunk away as it welds. And if the metal is not plain mild steel at all, the chart you are reading is the wrong chart, because the rod has to be matched to the alloy, a separate selection problem covered in Alloy Steel Welding Electrodes: Selection, Use & Safety.
• Wrong diameter for the thickness. A 5/32 rod on 16-gauge sheet is a hole-burning machine. A 3/32 rod on one-inch plate never gets the heat in. Diameter sets your amperage floor and ceiling, and once plate thickness is outside that window, no amount of hand skill rescues the joint.
• Settings guessed instead of read. Turning the dial to “whatever worked last time” ignores that rod type, diameter, position and thickness all move the target. The chart exists so the guess is never necessary.

Symptom, Cause, Fix: Reading the Defect

Contamination is the number one cause of porosity. Oil, paint, rust or moisture on the base metal releases gas as it heats, a long arc lets atmospheric nitrogen into the puddle, and a draft blowing across the work strips away the flux’s shielding. Clean to bright metal, shorten the arc to roughly the rod diameter, and block the breeze.

Slag inclusions and cold lap usually come from travel speed that is too fast for the amperage, or from chipping slag out of a multi-pass weld without cleaning between passes. The next pass then welds onto slag instead of steel. Slow down, and brush every pass to shiny metal before laying the next one.

A rod that keeps sticking to the plate almost always signals one of three things: settings that are too low, an arc held too long, or a ground clamp biting onto painted or rusty steel. Clean the clamp location, raise the amperage, and shorten the arc.

What you see	Likely cause	The fix
Pinholes and porosity	Oil, rust, paint or moisture on the plate; long arc; wind	Grind to bright steel, shorten arc, shield the work area
Undercut along the toe	Too hot, too fast, wrong work angle	Drop 5–10 A, slow travel, feather the rod back into the toe
Slag trapped between passes	Fast travel plus uncleaned passes	Chip and wire-brush to bare metal before each pass
Cold lap / lack of fusion	Too cold or too fast for the diameter	Raise amperage, slow down, or step down a rod size
Burn-through on thin steel	Rod and amperage too heavy for thickness	Switch to 3/32, lower the dial, use a stitching motion
Rod sticks to the plate	Low settings, long arc, dirty ground	Raise amps, shorten arc, relocate the clamp to bare metal
Heavy spatter, loud popping	Long arc, or a damp E7018	Tighten arc length; store rods dry and re-bake low-hydrogen rods
Cracked or snapping bead	Wrong electrode for a load-bearing joint; too much heat input	Use E7018 for structural work, control heat, preheat thick sections

For a sanity check on whether a bead passes, the visual acceptance criteria used across the industry come from the American Welding Society, whose standards also define the classification codes printed on your rod box.

A Short Troubleshooting Routine When the Weld Fails

1. Stop and let it cool. Diagnosis on a hot, slag-covered weld is guesswork.
2. Read the bead, then the surface. Porosity points at the plate first; sticking points at the machine and ground.
3. Go back to the chart. Confirm diameter, rod type, position and thickness against the recommended amperage window.
4. Check your consumables. Is the rod actually the one on the chart, and is it dry?
5. Change one variable. Move 5–10 A, nothing else, then run a fresh coupon.
6. Re-test on scrap of the same thickness before touching the project again.

Position work magnifies these defects, and much of what looks like poor technique overhead or vertical-up is really a chart reading problem: the wrong diameter for the position, or amperage set for flat used out of position. That is exactly what the All Position Welding Rod Guide: Types, Uses & Tips is for. Fix the input — rod, diameter, setting, clean steel — and most “skill” problems disappear on their own.

Stick vs MIG vs TIG, Practice Projects and Your Next Steps

You can now read a rod box, match a diameter to plate thickness, and pull an amperage range off the chart instead of guessing. What is left is context: stick is only one process among several, and the chart helps you only after you have confirmed stick is the right process for the job in front of you.

How the Three Common Processes Compare

Factor	Stick (SMAW)	MIG (GMAW)	TIG (GTAW)
Startup cost	Lowest: power source, holder, ground clamp, rod packs	Higher: adds gas cylinder, regulator, wire feeder and gun	Highest: torch, foot pedal, shielding gas, filler rod
Learning curve	Steepest arc control, but forgiving equipment	Fastest to learn; wire feeds continuously	Slowest; demands both hands and often a foot pedal
Outdoors	Excellent; flux coating shields the puddle	Weak in wind and drafts that blow gas away	Very gas-sensitive outdoors
Material range	Thick steel, rusty or painted steel, pipe	Thin steel fast, plus aluminum with the right setup	Thin, stainless, aluminum, critical work
Cleanup	Slag to chip and brush	Little slag, some spatter	Cleanest bead, minimal cleanup

Stick is almost always the cheapest way to start. A basic machine, an electrode holder, a ground clamp and a box of rods will burn steel all day, with no cylinder to rent and no regulator to set. There is a deeper reason it stays relevant: the flux coating creates its own shielding and, on cellulose rods, produces a forceful arc that digs through mill scale, paint and rust. That is why stick remains the default for farm repairs, structural work and field jobs, as covered in Advantages of Stick Welding: Why SMAW Still Wins. You can also explore how flux shielding works outside the stick process.

MIG is generally faster to learn because the wire feeds continuously, so you never stop to replace a consumed electrode, and the arc is easier to hold steady. Its weakness is environmental: wind and shop drafts disrupt the shielding gas, while a stick electrode still protects its own puddle. For aluminum specifically, MIG is the practical choice at home, and the setup details matter, which is why we put together a complete practical guide to aluminum MIG welding.

TIG produces the cleanest, most precise welds on thin material, stainless and aluminum, but it is slower and demands far more hand control than stick. Most welders learn stick first and add TIG later, when a project actually calls for that precision.

Which Process Should a Beginner Learn First?

If your budget allows only one machine, start with stick. It is the cheapest entry, it works indoors and out, and the discipline it builds, arc length, travel speed, heat settings, transfers directly to every other process. The Bureau of Labor Statistics treats welders, cutters, solderers and brazers as a major skilled-trades occupation with published employment and wage data, which underscores a simple point: rod selection is a workplace skill, not just a hobby one. Learn MIG next if most of your work is clean steel in a shop, then TIG once thin or cosmetic joints become routine. If a career interests you, our overview of aluminum welding courses explains what formal training covers and what it costs.

Practice Projects That Build Chart-Reading Skill

• Flat butt joints on 1/8-inch plate: the purest chart exercise. Set the machine from the recommended band, run a bead, chip the slag, and judge penetration.
• A small square-tube frame: teaches tacking, distortion control, and stepping down a diameter on thinner wall tubing.
• A shop gate or bracket set: introduces fillet welds, fit-up gaps, and repositioning the work so you practice horizontal and vertical passes.
• Pipe coupons or short offcuts: cheap scrap for repeating the same joint until your settings stop being guesses.

Beginner Buying Checklist

• Two or three 5-pound rod packs: E6013 and E7018 in 1/8 inch, plus 3/32 inch for thin steel
• An auto-darkening helmet and properly rated welding gloves
• A chipping hammer and wire brush for slag and spatter
• Clamps and a welding stake or fixture to hold work in position
• Sealed rod storage, ideally a dry box, because E7018 picks up moisture

Your Next Steps

Everything here reduces to one habit: let the chart answer four questions before you strike an arc. What is the base metal thickness? What position am I welding in? Which rod and diameter fit both? What polarity and amperage window does that rod want? Burn-through, cold lap and cracked beads almost always trace back to skipping those questions, not to bad equipment. Print the chart, tape it inside your rod cabinet, and read it every time for the first few months. Soon you will know the setting before you look it up. The chart gets you running; the practice projects make it instinct.

Frequently Asked Questions

What is a beginner welding rod chart?

A welding rod chart is a lookup table that matches your base metal thickness and weld position to an electrode type, diameter, polarity and amperage range. Instead of guessing, you find your plate thickness, read across to the suggested rod and setting, and start there before fine-tuning by ear and sight.

Which welding rod should a beginner buy first?

Most beginners do well starting with a pack of 1/8 in and 3/32 in E6013 for clean mild steel practice, plus a pack of E6011 for rusty or dirty repair work. Add E7018 only once your machine can run DC and your metal is clean, since it rewards good preparation with much stronger, cleaner welds.

What do the numbers on welding rods mean?

In a code like E7018, the E means electrode, 70 means a minimum tensile strength of 70,000 psi, the 1 means the rod is qualified for all welding positions, and the 8 identifies a low-hydrogen coating usable on DC and most AC currents. The same code tells you both strength and technique requirements.

What amperage should I use for a 1/8 inch rod?

A good starting point for 1/8 in rods on mild steel is roughly 110-125 A, with E6010 around 75-125 A on DCEP, E6011 around 80-130 A and E7018 around 110-165 A. Adjust in 5-10 A steps: too cold and the rod sticks, too hot and you get spatter and burn-through.

What is the difference between E6013 and E7018?

E6013 has a soft, forgiving rutile arc with shallow penetration, easy slag and a smooth bead, making it ideal for beginners and thin material. E7018 is a low-hydrogen rod that produces stronger, tougher welds with minimal spatter but requires clean, dry metal and careful rod storage.

Can I run E6010 or E7018 on an AC welder?

E6010 is a DC-only electrode, so it will not run properly on an AC-only machine. E6011 is the AC-compatible alternative for the same deep-penetrating cellulose arc, while standard E7018 performs best on DC and is available in AC-stabilized versions for older machines.

Why does my welding rod keep sticking to the metal?

Sticking almost always means your amperage is too low, your arc length is too long, or your ground clamp is on a painted or rusty spot. Raise the setting slightly, hold the arc about one electrode diameter from the plate, and clean the ground contact area.

Do I have to keep E7018 rods in an oven?

E7018 rods absorb moisture from humid air, and wet low-hydrogen electrodes can put hydrogen into the weld and cause cracking. Keep them in a sealed container or rod caddy, limit their open-air exposure according to the manufacturer’s guidance, and re-bake them at the recommended temperature when they have been exposed too long.
