Push or Pull Stick Welding: Which Direction Is Right?

The bead looked perfect until the grinder hit it — a dark line of trapped slag ran down the center like a seam in cheap fabric. The instructor didn’t even look at the puddle. He just asked one question: “Were you pushing or pulling?” For stick welders, that single choice explains more defects than almost any other habit.

Push or Pull Stick Welding: The Short Answer and Why It Matters

The grinder has a way of finding the truth. A bead that looked sound can open up a dark seam of slag, and suddenly the welder is second-guessing the amps, the travel speed, and the direction the electrode was moving. For most stick welding, that last question has a straightforward answer.

Short answer: pull. For most SMAW work in the flat, horizontal, and overhead positions, use a drag or backhand technique. Tilt the top of the electrode about 5 to 15 degrees in the direction of travel so the arc leads the puddle and the slag trails behind it. Miller recommends this drag technique for those positions, and an open welding textbook describes the trailing angle as the most common travel angle in stick welding. Vertical-up welding is the big exception, where a push or forehand angle is standard.

That answer is not cosmetic. Travel direction changes where molten slag lands, how much arc force reaches the base metal, how deep the weld penetrates, how the bead profile fills, what you can see while welding, and how likely you are to trap a defect. Tulsa Welding School sums up the trade rule bluntly: “if there is slag, you must drag.” The reason is simple. Flux-covered processes leave slag, and slag that gets rolled into the puddle becomes a defect that a grinder will eventually expose.

Why Direction Changes More Than Bead Shape

Push and pull are not two names for the same motion. They put the arc in a different relationship with the metal that is still cold, the metal that is already molten, and the slag that is trying to solidify. That shift shows up in several ways:

• Slag placement: dragging keeps flux residue behind the arc, while pushing can drive it toward the leading edge of the puddle.
• Arc force: the direction of the arc changes whether it digs into fresh base metal or buffets metal that has just melted.
• Penetration: a drag angle often concentrates heat in the joint, while a push can spread it across a wider area.
• Bead profile: dragging tends to produce a narrower, more crowned bead; pushing can flatten and widen it.
• Visibility: dragging lets you watch the joint ahead of the puddle instead of looking through a pile of slag.
• Defect risk: slag inclusions, lack of fusion, and undercut all respond to changes in travel angle and arc length.

None of this makes push “wrong.” It means the direction has to match the position, electrode, joint, and procedure. A technique that works beautifully on a vertical-up root pass can create a slag trap on a flat fillet.

What This Guide Covers, and Who It Is For

This article looks at travel direction across flat, horizontal, vertical-up, vertical-down, and overhead welding. It also covers open root passes, pipe work, thin sheet, hardfacing, and restricted-access joints, because those are the situations where the default answer often needs adjusting. The goal is not to memorize one angle and apply it everywhere. It is to understand why the angle changes and how to judge the result.

Beginners and hobbyists will get a clear starting point and a way to practice it. Working welders can use the position-by-position guidance and troubleshooting tables as a refresher. Inspectors-in-training will find the connection between technique and the defects they are likely to see on a weld inspection report. If you are still matching an electrode to a joint, our all position welding rod guide explains how classification and position fit together.

The sections ahead define forehand, backhand, drag, and travel angle without the usual jargon muddle. Then we will look inside the arc at slag and arc force, build the case for dragging as the default, and walk through every position. After that come the legitimate exceptions, the settings that override direction, the defects to watch for, and three practice drills you can run on scrap. By the end, you should be able to choose a direction deliberately instead of copying whatever feels comfortable.

Push vs Pull Stick Welding Defined: Forehand, Backhand, Drag, and Travel Angle

Before you can settle the push-or-pull argument, you need a shared vocabulary. Welders often use “push,” “pull,” “forehand,” “backhand,” and “drag” as if they mean the same thing in every conversation. They do not. In stick welding, those words describe two things at once: which way the electrode is tilted, and whether the arc is ahead of or behind the molten puddle.

The Four Terms, Pinned Down

Push means forehand. The electrode tip points in the direction you are traveling, so the arc sits ahead of the puddle. Pull means backhand or drag. The electrode tip points back toward the completed weld, so the arc sits behind the puddle.

Kobelco’s welding guidance defines backhand as a drag angle of 10–20 degrees pointing opposite the travel direction, and forehand as a push angle of 10–20 degrees pointing toward travel (Kobelco Welding). The same comparison notes that backhand welding tends to produce a convex bead with deeper penetration, while forehand tends to produce a flatter bead.

Here is the part beginners miss: your hand can move from left to right in either technique. What changes is where the arc sits relative to the puddle and the finished weld. That is why “pushing the puddle” and “pulling the puddle” are shorthand descriptions, not literal instructions to shove molten metal around.

Travel Angle and Work Angle Are Not the Same Thing

Work angle is measured across the joint, viewed from the end. For a butt joint, the electrode is normally held at about 90 degrees to the plates. For a fillet weld, the work angle is usually about 45 degrees to each leg, adjusted to balance heat between the two plates.

Travel angle is measured along the seam, in the direction of travel. Illinois State Board of Education SMAW training materials specify a 90-degree work angle viewed from the end of the joint and a 5–15 degree travel angle (ISBE). Those are two separate measurements. A welder can have a perfect 90-degree work angle and still ruin the bead with a 35-degree drag angle.

Nickel-alloy SMAW guidance shows how much the travel angle can vary by application. Haynes International describes directing the electrode back toward the molten pool with roughly a 20–40 degree drag angle for nickel-base alloys. The lesson is not that 5–15 degrees is wrong. It is that electrode type, position, and procedure can shift the number.

Three more descriptors keep the geometry clear:

• Leading arc: the arc is ahead of the puddle, which is the push or forehand arrangement.
• Trailing arc: the arc is behind the puddle, which is the pull, backhand, or drag arrangement.
• Perpendicular: a zero-degree travel angle, with the electrode straight up and down. It is neither a meaningful push nor a meaningful pull, and it often makes slag control harder.

Push vs. Pull at a Glance

Direction	Penetration	Bead shape	Slag position	Visibility	Spatter tendency	Typical use
Push / forehand	Generally shallower	Flatter and wider	Can be driven ahead of or around the puddle	Good view of the joint ahead, but slag may interfere	Often higher, especially at steep angles	Vertical-up, thin sheet, open roots, some repair work
Pull / backhand / drag	Generally deeper	More convex and narrow	Trails behind the arc	Usually clearer puddle and joint view	Often lower when the angle is controlled	Flat and horizontal work, thicker steel, structural fillets

Why the Shorthand Works, and Where It Breaks

“Push the puddle” and “pull the puddle” are useful because they focus on the puddle rather than the hand. In a push, the arc is working on metal ahead of the pool. In a pull, the arc is working behind the pool, over metal that has already been melted. That difference affects how much base metal the arc can bite into, how the slag behaves, and how much of the joint you can actually see.

The shorthand breaks down when someone treats it as a rule about hand motion. Dragging is not “pulling the electrode backward through the puddle.” It is holding the electrode at a backhand angle while the arc trails the pool. The distinction matters when you read a procedure or try to copy a technique from a video.

Terminology Gets Slippery Across Processes

Do not carry stick-welding definitions straight into MIG or TIG. In MIG welding, pushing is often the default because it improves shielding-gas coverage, while pulling may be used when more penetration is wanted. In TIG and brazing, “forehand” can mean the torch is angled forward with the filler rod leading the arc. That is a different geometry from stick’s forehand push. When someone says “forehand,” ask which process they mean.

With the vocabulary settled, the next question is what the arc is actually doing to the metal, and why dragging so often wins in stick welding.

What Happens Inside the Arc: Slag, Arc Force, and Penetration

The arc is only a few millimeters tall, but an enormous amount of chemistry and physics happens inside that gap. When you strike up, the flux coating on a stick electrode doesn’t sit there passively. It melts, burns, and off-gasses, throwing a blanket of shielding gas around the molten puddle while the leftover minerals float to the surface and freeze into slag over the finished bead. That single fact is the reason travel direction matters so much in stick welding: the slag has to go somewhere, and where the arc points decides whether that somewhere is behind you or inside your weld.

The arc also carries momentum. It isn’t just a heat source; it’s a jet of ionized gas with real force behind it. At normal current the cone is stiff enough to shove molten metal aside and dig into the joint, which is exactly how fusion reaches below the surface. Point that jet at cold plate and it behaves one way. Point it at a puddle you just made and it behaves another. Everything else in this section flows from that difference.

Dragging: Driving the Arc Into Cold Metal

When you drag, the electrode tip angles back toward the completed weld and the arc leads the puddle into untouched base metal. That metal is still at room temperature, so the heat has nowhere to spread except down and in. The result is a concentrated, digging arc, a puddle that trails behind the electrode, and typically deeper penetration with a narrower, more crowned bead profile.

There’s a second benefit that’s easy to miss. Because the puddle sits behind the arc rather than under it, you’re looking into an open joint instead of a shiny mound of molten steel. Visibility improves, and so does your ability to watch the toes tie in.

Pushing: Running the Arc Into Its Own Puddle

Push, and the geometry flips. The arc now fires into metal it melted a fraction of a second ago. That liquid layer absorbs and deflects some of the arc force, so the digging action softens. Heat spreads sideways instead of straight down, which usually gives you a wider, flatter bead and shallower penetration at the same amperage. On thin material that’s a gift. On quarter-inch plate it can be the difference between a sound root and a cold one.

Slag: The Layer That Decides Your Defects

Slag is lighter than steel, so it floats. In a drag, the flux and slag trail behind the arc and solidify as a protective cap over the bead you just laid. In a push, the arc runs toward the puddle, and molten slag has a chance to be rolled forward and trapped under the metal before it can escape. That is the mechanical root of most slag inclusions in stick welding, and it’s why the old shop line exists: if there’s slag, you drag. The full picture of why dragging dominates is covered in our breakdown of the advantages of stick welding, but the short version is that flux-coated electrodes reward a technique that keeps the flux behind the puddle.

Heat Input, Gas Coverage, and Distortion

Direction changes how heat is distributed, not just how much you put in. A dragging arc concentrates energy in a narrow band, which is efficient for penetration but can leave a hard, narrow heat-affected zone. A pushing arc spreads the same energy across a wider area, which often means less distortion across thin panels but a greater chance of wandering off the joint line. Travel speed interacts with all of it: SMAW travel speeds commonly sit in the 3 to 6 inches per minute range (roughly 75 to 150 mm/min) depending on electrode and joint, and slower travel raises heat input regardless of which way you point the rod. Gas coverage follows the same logic. The flux cone and shielding gas protect the puddle in both directions, but dragging lets the freezing slag cap shield the bead as it cools, which is one more reason it’s the default.

What the Research Actually Shows

This isn’t folklore. A published study on submerged arc welding found that a backhand technique with a 45-degree electrode angle produced high penetration, while a forehand 45-degree angle produced a wider bead with less uniform bead formation. A review of SMAW process parameters in Heliyon likewise reports that, in one cited experiment on AISI 1020 plates, DCEN polarity with a 90-degree electrode angle at 120 A gave the highest penetration.

Read those results carefully, though. They confirm a trend, not a universal law. Bead geometry shifts with process, current, polarity, angle, and joint design, and a submerged arc result doesn’t transfer directly to a 7018 fillet on your bench. Treat direction as a strong modifier and verify on scrap. Electrode classification matters here too, which is why our all position welding rod guide pairs well with this discussion.

Why Pulling Is the Default in Stick Welding

Watch a good stick welder on a flat joint and the motion looks almost boring. The electrode leans slightly forward, the arc rides the leading edge of the puddle, and slag rolls out behind like a slow wave. That is not style. Dragging solves several problems at once, which is why pulling became the default.

Five practical advantages make the case. None is absolute, but together they explain why most stick welding is done backhand.

1. Slag Stays Behind the Arc

SMAW is a slag-producing process. The flux coating melts into shielding gas and a liquid slag layer that covers the bead as it cools. Tulsa Welding School groups stick welding with flux-cored and submerged arc for this reason, and states plainly that stick welding requires a pulling technique. Dragging keeps the arc ahead of the slag, so the puddle freezes behind the electrode and the flux blanket follows it.

Push instead and the geometry reverses. The arc runs toward slag you just made, and the puddle can roll over flux that has not fully escaped. The result is a slag inclusion: a dark glassy line trapped inside the bead that a grinder may only reveal later. Hence the old mnemonic, “if there’s slag, you must drag.”

2. You Can See the Joint, Not the Slag

Visibility is underrated. When you drag, you look into the open joint ahead of the puddle. The unwelded root, the gap, and both sidewalls stay in view. Push, and the puddle with its slag cap sits between your lens and the seam. Now you are steering by guesswork, especially in a deep groove or a tight fillet.

A slight drag also gives the arc a clear reference. Miller’s stick welding guidance recommends tilting the electrode 5 to 15 degrees in the direction of travel for flat, horizontal, and overhead work. That small angle keeps the arc leading without burying the electrode in the puddle.

3. Better Penetration and Tie-In on Thicker Steel

When the arc leads, it strikes relatively cool, unwelded base metal. Heat concentrates at the root and sidewalls, which generally improves fusion and penetration compared with running the arc into an already-hot puddle. On thicker steel, that difference shows at the toes and in the root.

Direction is not the main driver. Amperage, polarity, arc length, and joint preparation do most of the work. Dragging simply helps the arc do its job instead of buffering it against molten metal.

4. Procedures and Structural Work Expect It

Most flat and horizontal fillet procedures, and most groove welds in structural fabrication, are written and qualified around drag technique. That matters, because a procedure qualification is not a suggestion. If the WPS says drag, you drag, even if pushing feels smoother that day.

Inspectors also expect the bead profile that comes with a controlled drag: good toe wetting, a slightly crowned face, and slag that lifts cleanly. A pushed bead can look flatter and wider. That is not automatically wrong, but it is a different profile and may fall outside the qualified range.

5. Consistent Arc Length Is Easier

Arc length should stay close to the electrode diameter. Dragging makes that easier because the electrode naturally follows the seam, and the trailing slag gives you a visual gauge of travel speed. Your hand moves in a straight line, the arc stays short, and the bead stays uniform.

Pushing encourages a longer arc. The welder tends to lift slightly to see over the puddle, and a long arc brings spatter, porosity, and undercut with it.

The Mnemonic and Its Limits

“If there’s slag, you must drag” is a useful default, not a law. It holds for flat, horizontal, and most overhead stick work. Nickel-alloy guidance from Haynes International, for example, describes overhead SMAW as backhand welding with a drag angle of 0 to 20 degrees. But the rule breaks down in vertical-up welding, open-root passes, and some pipe procedures, where pushing is deliberate and qualified.

A Real-World Example: 1/4-Inch Fillet on A36 With 7018 at DCEP

Picture a tee joint in 1/4-inch A36 plate, welded with 1/8-inch E7018 on DCEP. Clean mill scale and oil from the joint. Set the current inside the manufacturer’s range for that diameter, then fine-tune on scrap.

Hold a work angle near 45 degrees, splitting heat between the plates. Tilt the electrode 5 to 15 degrees in the direction of travel. Establish the puddle at the start of the joint, then move at a steady pace while watching the toes. Slag should trail behind the arc, not run under it. Keep the arc short enough that the flux is almost touching the puddle.

Let the pass cool, chip the slag, and brush the bead. Look for even legs, smooth toe transitions, and no undercut on the vertical plate. If the bead is ropey or the spatter heavy, check your travel angle first. You may be dragging too steeply rather than too shallow. For electrode selection across positions, this all-position welding rod guide is a useful companion.

Pulling is the default because it protects the puddle from its own slag, keeps the joint visible, and makes a consistent arc easier to hold. Learn to drag well before deciding you are the exception.

Position by Position: Flat, Horizontal, Vertical Up, Vertical Down, and Overhead

Travel direction is not a setting you choose once and keep forever. Gravity changes where the puddle wants to fall, and the electrode changes how much arc force you can safely use. The welding position tells you which way the slag and molten metal will move when you are not looking. Here is how the recommendation shifts from the bench to the pipe rack.

Flat

Flat welding is the forgiving position and the one most beginners learn on. Drag the electrode at roughly 5–15 degrees of travel angle, with the work angle close to 90 degrees to the plate. A slight tilt is fine when the joint geometry calls for it, but do not turn a flat bead into a steep backhand just because it feels more aggressive. Keep your eyes on the puddle width. If the puddle spreads quickly and the toes look washed out, you are probably moving too slowly or running too hot. A steady drag keeps the slag behind the arc and gives you a clean view of the seam ahead.

Horizontal Fillet

Horizontal fillets add gravity to the problem. The puddle wants to sag toward the lower plate, while the vertical leg wants to undercut. Drag at about 5–15 degrees and aim the arc slightly upward into the vertical leg rather than letting it sit low in the corner. That small upward bias helps the molten metal bridge both legs without dropping. Watch the vertical toe closely. A fast, consistent drag usually produces a flatter, more even fillet than a push, which can pile metal on the bottom leg and leave undercut above.

Vertical Up

This is the big exception. Miller specifies a push, or forehand, technique for vertical-up stick welding, with the electrode angled about 0–15 degrees away from the direction of travel. The arc stays slightly ahead of the puddle, and the solidified bead below helps support the molten metal. Use lower current and a shorter arc than you would in flat position so the puddle does not sag. A small triangle or Z weave controls the width. Keep the arc at the top edge of the puddle and watch for slag rolling ahead of the arc, which is the classic vertical-up trap. Low-hydrogen electrodes such as 7018 are typically run vertical up, and the electrode classification matters as much as the position. Our all-position welding rod guide explains how those classifications affect technique.

Vertical Down

Vertical down is fast, drag-like, and shallow. The arc runs ahead of the puddle, gravity helps the slag stay away from the molten pool, and penetration is limited compared with vertical up. Cellulosic electrodes are associated with deep penetration and vertical-down root passes in pipeline work, where speed and root control matter more than filling a thick joint. Use a light drag angle, keep a short arc, and move faster than you think. This is not the direction for heavy structural groove welds or thick fillets that need deep fusion. Vertical down can look neat and still leave lack of fusion if the current is low or the travel speed outruns the puddle.

Overhead

Overhead welding requires a drag. Haynes International’s SMAW guidance specifies backhand welding with a 0–20 degree drag angle for overhead work, along with low current, a short arc, and a tight weave. Gravity is pulling the puddle and the slag straight down, so a push angle gives the molten pool a chance to fall into the arc and trap slag. Nickel-alloy SMAW is generally limited to 2.4 mm and 3.2 mm electrodes in out-of-position work, partly because smaller electrodes give better control when the puddle wants to drop. Keep the bead small, watch the edges, and do not try to carry a wide puddle overhead.

Position	Direction	Travel Angle	Current Tendency	Main Risk
Flat	Drag	5–15°	Normal range	Wide puddle, burn-through
Horizontal fillet	Drag	5–15°	Normal range	Undercut on vertical leg
Vertical up	Push/forehand	0–15° away from travel	Lower than flat	Slag rolling ahead, sagging puddle
Vertical down	Drag-like	Light drag, roughly 5–15°	Low to moderate	Lack of fusion, shallow penetration
Overhead	Drag/backhand	0–20°	Low	Falling puddle, trapped slag

The pattern is simple enough to remember: flat and horizontal work reward a steady drag, vertical up is the documented push exception, vertical down is a fast drag with limited penetration, and overhead work demands a drag with low current and a short arc. Get the position right first, then fine-tune the angle and arc length to what the puddle is actually doing.

When Pushing Works: Legitimate Exceptions to the Drag Rule

If dragging is the default, why do so many experienced welders push? Because stick welding is position-driven, not slogan-driven. In specific joints, electrodes, and procedures, forehand travel solves a real problem. The skill is knowing which problem, and not mistaking personal comfort for a qualified technique.

Vertical-Up: The Exception Most Procedures Actually Expect

Vertical-up is the clearest official exception. Miller recommends a push, or forehand, technique for vertical-up stick welding, and many low-hydrogen procedures show the same approach. As you climb, the solidified bead below helps support the puddle, gravity keeps slag low and away from the arc, and a slight upward push directs arc force into the sidewalls instead of letting the puddle sag. Done well, it produces a fuller bead and better toe wetting than a dragged vertical-up pass.

The angle is smaller than beginners expect. A common starting point is 0 to 15 degrees of push away from vertical travel, with a short arc and a tight triangle or Z weave. Haynes International describes a wider qualified window in vertical welding: forehand with up to a 20-degree push angle through to backhand with up to a 20-degree drag angle. That range is a useful warning that “vertical-up equals push” is still too simple; the electrode and procedure decide. The arc also has to bite the sidewalls. Push too flat and the puddle becomes a shelf, which invites cold lap at the toes.

Open Roots and Pipe: Choose Deliberately

Open-root groove welds are often called a push application, but the reasoning is easy to invert. Many open-root procedures actually specify a drag, or backhand, angle so arc force reaches the root rather than riding on the puddle. The root is a place where direction must be chosen deliberately, not a free pass to push.

With cellulosic electrodes on pipe, some procedures use a fast downhill root and hot pass; others require uphill. Some qualified procedures permit a slight forehand angle to keep the arc at the root, especially where access is tight. None of that is universal. Wall thickness, root gap, electrode, and the WPS decide, and the wrong direction can turn a clean root into lack of penetration or burn-through.

Thin Sheet, Buildup, and Hardfacing

When penetration is the enemy, pushing earns its place. Forehand welding tends to produce a flatter, wider bead, which can suit buildup and thin material where deep penetration is not wanted. On light gauge, a slight push and a brisk travel speed can keep the arc from knifing through. On hardfacing, a wider bead spreads dilution and covers more surface per pass. The trade-off is fusion: on thicker sections, that flatter profile can hide lack-of-fusion at the toes, so pushing is a poor default for structural plate. Electrode selection still matters, so check an alloy steel electrode guide before assuming a buildup rod behaves like 7018.

Repair Work, Stainless, Nickel, and Restricted Joints

In a tight repair, visibility can outweigh theory. Pushing lets you look into the joint ahead of the puddle instead of staring at slag, which is why some maintenance welders push in confined areas. A slight push is also permitted in some stainless and nickel-alloy procedures within qualified ranges; Haynes’s 20-degree window shows how formal that permission can be. Narrow-groove and restricted-access joints can fall into the same category when the only way to see the root is to lead with the arc. Convenience does not suspend the need for fusion, though. If you cannot confirm penetration, the repair is not finished.

Push Vertical-Up vs. Drag Vertical-Down

Technique	Typical use	Penetration	Bead shape	Main risk
Push vertical-up	7018 structural work, thicker plate, some open roots	Deeper sidewall fusion	Fuller, slightly convex	Slag rolling ahead when the weave is too wide
Drag vertical-down	Cellulosic pipe roots, thin sheet, fast fills	Shallow	Thin and flat	Lack of fusion on heavy steel

Cautions Before You Switch

• Do not push because it feels easier. Comfort is not a procedure qualification.
• Test on scrap. Use the same thickness, joint, and electrode, then cut and inspect the coupon.
• Read the WPS and electrode data. An all-position rod guide can clarify what a classification allows, but the project procedure still governs.
• Watch the slag line. Pushing sends the puddle toward slag that has not frozen, so inclusions appear quickly if the angle or arc length wanders.

Angle, Arc Length, Amperage, and Travel Speed: The Variables That Override Direction

Travel direction gets all the attention, but it is rarely the deciding factor in whether a bead passes inspection. Four other variables sit higher on the list: electrode angle, arc length, amperage, and travel speed. Get those wrong and a perfect drag still produces lack of fusion. Get them right and even an unusual push can hold up. A review published in Heliyon identifies current, polarity, electrode angle, arc length, and travel speed as the main SMAW process variables affecting weld quality. Direction matters, but it works inside that group, not above it.

Work Angle vs. Travel Angle

These are separate settings, and confusing them causes a lot of bad beads. Work angle describes the electrode’s position relative to the joint faces. Travel angle describes the tilt along the direction of travel. Kobelco’s technical guidance treats them as distinct variables, and both change bead shape and penetration.

A 90-degree work angle is the standard starting point for a square butt or a tee joint. In a horizontal fillet, that usually becomes roughly 45 degrees between the two plates, adjusted slightly upward so gravity does not pull the puddle down the vertical leg. Travel angle is the 5-to-15-degree drag or push discussed earlier. Some nickel-alloy and special procedures call for much steeper travel angles, sometimes 20 to 40 degrees, because the puddle needs different arc force. Those are qualified ranges, not general advice.

Arc Length: The Variable Beginners Neglect Most

Arc length is the gap between the electrode tip and the puddle. Tulsa Welding School advises matching arc length to electrode diameter, so a 1/8-inch electrode runs roughly a 1/8-inch arc. That is a useful physical gauge you can hear and feel.

• Too long: the arc wanders, spatter increases, shielding weakens, and you risk porosity and undercut. Arc blow gets worse.
• Too short: the electrode sticks, the puddle freezes, and slag can get trapped because the arc cannot push it clear.

Arc length also changes penetration. A tight arc concentrates heat; a long arc spreads it and loses directional force. That is why two welders using the same drag angle can get completely different results.

Amperage and Polarity

Amperage does more for penetration than direction ever will. Stay inside the electrode manufacturer’s recommended range, then fine-tune to the joint and position. AWS A5 electrode classifications such as E6010, E6011, E6013, and E7018 encode tensile strength, position capability, coating type, and current type. That is why two 1/8-inch electrodes can demand very different techniques. Our all-position welding rod guide breaks down those classifications further.

Polarity shifts the balance too. DCEP generally gives deeper penetration and is standard for 7018. DCEN reverses that relationship, producing shallower penetration and higher deposition, which suits some surfacing and thin-material work. AC sits in between and helps with arc blow. None of this overrides the electrode’s qualified current type.

Travel Speed and Electrode Condition

Travel speed controls bead size and heat input. Too fast gives a thin, narrow bead with poor toe wetting and likely lack of fusion. Too slow gives a wide, convex bead, a heavy slag pile, and possible burn-through on thin plate. Aim for a consistent speed that lets the puddle wet both toes without running ahead of the arc.

Electrode condition is the quiet variable. Damp 7018 is not the same electrode as dry 7018. Low-hydrogen electrodes should be stored and reconditioned according to the manufacturer’s guidance, because moisture drives porosity and hydrogen cracking.

Starting Points for Common Electrodes

Electrode (1/8 in.)	Typical Amperage	Polarity	Practical Note
E6010	75–110 A	DCEP	Deep digging arc; whip technique common on pipe
E6011	80–120 A	AC or DC	Forgiving on dirty or rusty steel
E6013	90–130 A	AC or DC	Smooth, shallow penetration; good for sheet
E7018	90–130 A	DCEP or AC	Low hydrogen; keep dry and use a tight arc

Treat these as starting points, not procedure approval. Miller’s stick welding guidance makes the same point: settings are a baseline that gets adjusted to the joint, position, and machine. A WPS number always wins over a chart on a website.

If you change direction and the bead still fails, the problem is probably in this group of variables. Fix the arc length first, then the amperage, then the travel speed. Direction is the last dial to turn, not the first.

Common Mistakes, Defects, and a Troubleshooting Workflow

Everything so far has been theory. In the shop, nobody hands you a defect label: you get a bead that looks off, a dark line the grinder reveals, or an inspector who says, “Cut that out.” Most stick problems follow patterns, and the patterns are readable.

The Seven Defects That Show Up Again and Again

Slag inclusions are the signature failure of the push-or-pull debate. Flux residue gets trapped in or along the weld because slag sat ahead of or inside the pool and was covered before it could float out. The American Welding Society treats it as a recognized defect, and it is the main mechanical reason dragging is standard practice. Pushing on flat or horizontal work rolls slag into the puddle’s path, and a long arc stirs a wide, turbulent pool that swallows it.

Lack of fusion is the quiet one. The bead looks fine, but the toes never wet into the sidewall: travel too fast, amps too low, arc drifting long, or a steep drag scattering arc force instead of digging.

Undercut is a groove melted beside the bead. Excess current is the classic cause, but so is a work angle that blasts one leg of a fillet, or a weave that races the center and lingers at the edges.

Porosity is gas that never escaped or never arrived: long arcs, damp 7018, wind, and oil, paint, galvanizing, or rust cooking off in the arc.

Arc blow bends the arc sideways or backward near joint ends, corners, or a distant ground. Shorten the arc, move the ground, change the return path, or switch to AC if the procedure allows.

Overlap, or cold lap, is the puddle outrunning the arc: metal lays over base metal without fusing, then peels or cracks. It loves an overdone drag angle.

Ropey convex beads bring a high crown, tight ripples, and rolled edges: too slow, too steep, or too little current. Not always rejectable, but it flags poor toe fusion and a stress concentration.

Symptom, Cause, Fix: A Field Diagnosis Table

Symptom	Likely Causes	First Fix
Slag inclusions	Pushing, long arc, skipped cleaning	Drag, short arc, chip every pass
Lack of fusion at toes	Fast travel, low amps, long arc	Slow down, add amps
Undercut	High amps, bad work angle	Lower amps, flatten angle
Porosity	Long arc, damp rod, wind, dirt	Short arc, dry rod, clean plate
Arc blow	Long arc, remote ground, edge work	Short arc, move ground, try AC
Overlap / cold lap	Puddle outrunning arc, heavy drag	Slow the travel, ease the angle
Ropey convex bead	Slow, steep, low current	Speed up, flatten, add amps

The Cleaning Routine That Prevents Half of These

Most slag inclusions are self-inflicted, and about ninety seconds per pass prevents them:

1. Chip. Run the hammer along the full bead, including the toes where slag hides in the corner of a fillet.
2. Brush. Remove the fines the hammer missed, with a brush dedicated to that base metal.
3. Grind. Heavy shelves, toe spatter, or lumpy restarts get a light touch. Remove what could trap; don’t polish.
4. Inspect. Grind trapped slag out before the next pass, because if you cover it, you own it.

That last step matters most, and it is exactly the habit Miller’s five steps for improving stick technique emphasizes. Step into more advanced work later — an all position welding rod guide, a new process — and the same discipline follows you.

The Five-Step Troubleshooting Workflow

When a weld goes bad, resist changing three dials at once. Work in order:

• Check the WPS. Confirm amperage, polarity, electrode, and travel direction. On structural steel, AWS D1.1 governs procedure qualification and inspection, and a deviation you missed is a defect waiting to happen.
• Check the machine. Loose ground, wrong polarity, a dial that reads 120 and delivers 95, a cable with a broken strand.
• Check the electrode. Right classification? Dry? Stored properly? A 7018 left in humid air is a porosity machine.
• Check angle and arc length. Free to adjust, and they fix a surprising share of fusion and cosmetic issues.
• Change one variable at a time. Test bead, look, adjust one thing. Anything else teaches you nothing.

Reading the Bead Before You Chip It

Judge the weld while it’s hot. Ripple spacing shows travel speed, the wet line at the toes shows fusion, and rounded rather than feathered edges mean low heat or fast travel, whatever the crown says. Fine spatter everywhere points to a long arc; spatter crowded on one side points to an angle problem. A thin or broken slag crust suggests the arc ran long or the current was low — cheaper clues than a grinder and an inspector.

One More Thing About Direction and Defects

Travel direction shows up in the causes constantly. It is rarely the whole story, since amperage and arc length outrank it, but direction decides where slag goes, and that decides whether slag lands in your weld. That is why flipping from push to drag, everything else untouched, clears up so many inclusions on flat and horizontal work. Gas-shielded processes care more about coverage than slag, which is why their conventions differ; on aluminum, guides like aluminum MIG welding show where those habits come from.

Next: drills you can run this weekend, process comparisons, and a decision framework.

Practice Drills, Process Comparisons, and a Simple Decision Framework

Reading about travel angle is easy. Feeling the difference between a bead that wets in nicely and one that sits on top of the plate like a caterpillar takes repetition. The good news is that you do not need expensive material or a stack of coupons to build that feel. Three simple drills, run on scrap with the same machine settings, will teach you more about push versus pull than a week of forum threads.

Drill 1: The Bead-on-Plate Pad

Set up a flat piece of 1/4-inch or 3/8-inch mild steel and run a pad of straight stringer beads — no weaving. Run five beads dragging at roughly a 10-degree travel angle. Then, without touching the amperage, run five more pushing at the same angle and speed. Let the plate cool, chip and brush it clean, then lay the two groups side by side.

You are looking for four things: bead width, crown height, toe wetting, and where the slag ended up. Drag beads usually come out narrower and slightly more convex with tighter toes. Push beads tend to be wider and flatter, and the slag line often sits differently relative to the puddle edge. On a cut-and-etched cross-section, the difference in penetration profile is usually visible too.

Drill 2: Vertical-Up Push Weave on 3/8-Inch Plate

Vertical up is where pushing earns its place, so practice it deliberately. Use a low-hydrogen electrode like 7018 on 3/8-inch plate, set a short arc, and run a triangle or Z weave while pushing upward with the electrode angled 0 to 15 degrees away from the direction of travel. Keep the arc length tight — roughly equal to the electrode diameter, which is one of the five fundamentals Miller’s stick welding guidance is built around.

Watch the top edge of the puddle, not the slag. If slag starts rolling down ahead of the arc, your weave is too wide, your arc is too long, or you are moving too slowly. The solidified bead below you is doing real work here, supporting the puddle so gravity does not drop it out of the joint.

Drill 3: The 10-Degree vs 20-Degree Fillet

Set a tee joint and run a horizontal fillet with a deliberate 10-degree drag. Then run an identical pass at 20 degrees. The second bead will feel easier and look worse — you will likely see more spatter, a ropey profile, and possible undercut on the vertical leg. That contrast is the whole lesson: past about 15 to 20 degrees of drag, the arc stops behaving and starts blasting.

Stick vs MIG, Flux-Cored, and TIG

Stick welding’s drag default comes from slag, not from gas coverage. Other processes flip the logic:

Process	Common default	Why
SMAW (stick)	Drag / backhand	Keeps slag behind the arc, better visibility and penetration
MIG (GMAW)	Push / forehand	Better shielding gas coverage and bead appearance; pulling tends to dig deeper
Flux-cored (FCAW)	Drag	Flux and slag control, similar reasoning to stick
TIG (GTAW)	Push / forehand	Gas coverage and clear view of the puddle

The MIG contrast is worth internalizing because it trips people up when they switch processes. Kobelco’s comparison of forehand and backhand technique notes that each has advantages and disadvantages when all other conditions are held constant — and in gas-shielded MIG, pushing is commonly preferred for gas coverage while pulling tends to give deeper penetration. If you also weld aluminum, the same push bias carries over in the aluminum MIG welding guide, where gas coverage matters even more.

A Simple Decision Framework

1. Position first. Flat, horizontal, and overhead default to drag. Vertical up is the documented push exception.
2. Electrode type second. Cellulosic electrodes behave differently from low-hydrogen, and all-position rod selection changes what the puddle will tolerate.
3. Joint and thickness third. Open roots and thin sheet may need different arc force placement than a heavy fillet.
4. The WPS fourth. If a procedure specifies direction, angle, or technique, that is the answer. Full stop.
5. Personal comfort last. Comfort is only valid if the first four questions are already satisfied.

What to Master Next

Once direction feels natural, the next three skills to chase are arc length consistency, travel speed, and reading the puddle. Direction is a starting point; those three are what separate a welder who passes a bend test from one who hopes. Run another pad tomorrow, change one variable, and look at the result with a chipping hammer in hand.

Conclusion: Drag by Default, Push by Exception, and Verify With the Procedure

If you take one rule from this whole guide, make it this: in most stick welding, you drag. Pulling keeps the slag behind the arc where it belongs, lets you see the joint ahead of the puddle, and gives you the penetration and tie-in that structural work expects. Miller’s own stick technique guidance puts flat, horizontal, and overhead work at a 5–15 degree drag angle, and that number is a good default to carry in your head.

The documented exception is vertical up, where the recommendation flips to a 0–15 degree push. That is not a loophole or a style preference. The solidified bead below the puddle helps hold the molten metal, the slag tends to stay put instead of rolling into the arc, and the arc force can reach the root instead of skating across it. Low-hydrogen electrodes such as 7018 are where this push shows up most often.

The Numbers Worth Remembering

• 5–15 degrees travel angle for typical drag work. Past roughly 15–20 degrees you start buying spatter, undercut, and a ropey bead.
• 0–15 degrees push for vertical up.
• 90-degree work angle as the baseline, tilted slightly for gravity in fillets.
• Arc length near one electrode diameter — short enough to stay stable, long enough not to stick.
• Roughly 3–6 inches per minute travel speed in Haynes International’s nickel-alloy SMAW guidance, a reminder that stick travel is slower than most beginners expect.

Direction Follows Position and Electrode, Not Habit

Position changes everything. Flat and horizontal fillets want a drag. Overhead demands one. Vertical down with cellulosic electrodes behaves like a fast drag with limited penetration. Vertical up with low-hydrogen rods wants the push. Electrode classification matters too, which is why a rod chart such as our all position welding rod guide is worth keeping near the machine.

And on code-governed work, none of this outranks your paperwork. A qualified welding procedure specification governs travel direction, angle range, current, and pass sequence. Where a WPS exists, it wins. Every time.

Safety Reminders Before You Strike an Arc

Stick welding throws sparks, infrared radiation, and metal fume. Wear a properly shaded helmet, flame-resistant clothing, leather gloves, and eye protection under the hood. Weld with ventilation or fume extraction, especially on galvanized, painted, or alloy steel. Keep a fire watch and clear combustibles from the area. These requirements sit inside OSHA 29 CFR 1910.252, which covers personnel protection and fire prevention for welding operations.

The Screenshot Checklist

1. Read the WPS. If there is one, follow it exactly.
2. Default to a 5–15 degree drag, 90-degree work angle, arc length near one electrode diameter.
3. Vertical up with low-hydrogen rods? Switch to a 0–15 degree push and a short arc.
4. Clean slag between every pass — chipping hammer, brush, grinder where needed.
5. Change one variable at a time when troubleshooting.
6. Test any new direction on scrap before it goes on a real joint.
7. Inspect the toes, not just the crown.

Here is the part that matters most: travel direction is a skill, not an identity. Nobody is “a pusher” or “a dragger.” Good welders read the position, the electrode, the joint, and the procedure, then pick the direction that keeps slag out of the puddle. Run a pad of beads dragging, then pushing, same settings, and cut the plate in half. The cross-section will teach you more in ten minutes than a month of forum arguments. Keep practicing, keep reading your puddle, and keep verifying against the procedure — that is how a habit becomes a judgment call.

Frequently Asked Questions

Do you push or pull when stick welding?

In most positions you pull, also called dragging or backhand welding, so the arc leads and the slag trails behind the puddle. The main exception is vertical-up welding, where a push or forehand technique with the electrode tilted slightly away from travel is commonly recommended. Always follow the qualified procedure for code work.

Why do you drag when stick welding but push when MIG welding?

Stick welding produces slag from the flux coating, so dragging keeps that slag behind the arc instead of rolling it into the weld. MIG welding has no slag and relies on shielding gas, so pushing improves gas coverage and gives a flatter, cleaner-looking bead. Different processes, different priorities.

What angle should a stick electrode be held at?

A common starting point is a 90-degree work angle to the joint and a 5-15 degree travel angle, tilted in the direction of travel for a drag. Some procedures and materials call for steeper angles, such as 20-40 degrees in certain nickel-alloy work, so check the electrode manufacturer and the WPS.

Does pushing give less penetration in stick welding?

Often yes, because the arc runs into the puddle it just created, which can buffer arc force and spread the heat. But direction is a secondary factor: amperage, polarity, arc length, joint preparation, and travel speed usually influence penetration more than push versus pull alone.

Can you push 7018 vertical up?

Yes. Vertical-up welding with low-hydrogen electrodes like 7018 is typically done with a slight push or forehand angle, a short arc, and a controlled weave. Keep the puddle small and watch that slag does not roll ahead of the arc, which causes inclusions.

Is vertical down stick welding a pull or a push?

Vertical down is generally run with a drag-style motion and fast travel, often with cellulosic electrodes on pipe root passes. It offers limited penetration and is not appropriate for many structural applications, so verify the procedure before using it.

Why do I get slag inclusions even when I drag?

Dragging helps, but a long arc, too steep an angle, low current, fast travel, or poor cleaning between passes can still trap slag. Chip and brush each pass thoroughly, keep the arc short, and hold a consistent angle before blaming travel direction.

What arc length should I use for stick welding?

A practical rule is to match arc length to electrode diameter, so a 1/8-inch electrode runs about a 1/8-inch arc. That keeps the arc stable and the shield intact without excessive spatter, porosity, or sticking.
