Stick welding (SMAW) puts the quality of the weld directly in your hands See our stick welding AWS classification guide for more on this topic.. Unlike automated processes, the bead you produce depends on how you control four technique variables: arc length, travel speed, rod angle, and your choice of bead pattern. Get these right, and your welds will be consistent, strong, and clean. Get them wrong, and you will fight spatter, slag, porosity, and poor penetration.
The good news is that these skills are learnable. Every experienced welder started where you are now, running beads on flat plate and learning to read the weld puddle. This guide covers the four technique variables one at a time, with specific guidance for common electrodes like 6010 and 7018. All amperage, angle, and speed values here are starting points – the manufacturer data sheet for your electrode and your project’s Welding Procedure Specification (WPS) are the final authorities.
Safety Precautions
Before you strike an arc, make sure you have the right gear. Wear a welding helmet with an ANSI Z87.1 compliant shade filter. UV radiation from the arc causes welder’s flash – keep all skin covered with flame-resistant clothing, leather welding gloves, and leather boots. Stick welding produces fumes containing manganese, chromium, and iron oxide. Always weld in a well-ventilated area. If you see smoke collecting, stop and improve ventilation before continuing. Hot slag and spatter travel several feet – clear the area of combustibles (OSHA requires 35 feet minimum per 29 CFR 1910.252(a)). Keep a fire watch nearby when welding near flammable materials.
Why Stick Welding Technique Matters
Stick welding is operator-dependent. The machine delivers amperage, but you control everything else. Correct technique produces a consistent bead profile, proper penetration, slag that lifts off cleanly, and welds that meet code requirements.
Poor technique causes defects. A long arc creates spatter and porosity. Travel speed that is too fast produces undercut and cold lap. The wrong rod angle causes lack of fusion or slag entrapment. These problems are not random – they follow predictable patterns based on how you handle the electrode.
The four technique variables covered here give you a framework for troubleshooting your own welds. When a bead does not look right, you can check arc length first, then travel speed, then rod angle, then bead pattern. Adjust one variable at a time on a practice plate and observe what changes.
For readers who encounter specific weld defects and need to identify and fix them, see our Common Stick Welding Defects guide for detailed troubleshooting of technique-related problems.
Arc Length: The Foundation of Bead Control
Arc length is the distance between the tip of the electrode and the workpiece. It is the first variable to master because it affects everything else – bead width, penetration, spatter, and arc stability.
Correct Arc Length
A common starting point is approximately the diameter of the electrode core wire. For a 1/8 inch (3.2 mm) electrode, that means an arc length of roughly 1/8 inch. This produces a steady, consistent burn-off of the electrode into the weld puddle.
Some electrodes require different arc lengths. E6010 and E6011 (fast-freeze electrodes) run with a slightly longer arc, about 1/8 to 3/16 inch, to support the whip-and-pause technique. E7018 (low-hydrogen) runs best with a short arc of 1/8 inch or less and a steady drag. Always check the electrode manufacturer’s recommendation for the specific product you are using.
Listen for the Crackle
Experienced welders listen for a steady crackling sound like bacon frying. This is a reliable indicator of proper arc length – an observational technique, not a manufacturer specification. If you hear hissing, the arc is too long. If you hear popping or the electrode sticks, the arc is too short. Learn to hear the difference and adjust before you weld.
Arc Too Long
When the arc length exceeds roughly the diameter of the electrode, several things happen. The arc becomes less stable and produces excessive spatter. Atmospheric gases (oxygen and nitrogen) contaminate the molten weld metal, creating porosity. The bead profile becomes wide and flat with a rough surface. Undercut may appear at the edges of the bead.
A long arc also changes the sound. Instead of the steady crackle, you hear a hissing or sizzling noise. The arc appears visibly longer and wanders more.
Arc Too Short
When the electrode is held too close to the workpiece, the electrode tip tends to stub or stick to the base metal. The arc becomes unstable and may extinguish. Slag can become trapped in the weld because the puddle does not have room to flow properly. The bead profile is narrow and crowned, with poor sidewall fusion.
Arc length interacts with amperage. Higher amperage lengthens the arc column naturally. Lower amperage shortens it. Beginners should set amperage within the manufacturer’s recommended range first, then fine-tune arc length by raising or lowering the electrode tip position.
Travel Speed: Controlling Bead Width and Profile
Travel speed is how fast you move the electrode along the joint. It directly determines bead width, penetration depth, and the ripple pattern of the finished weld.
Correct Travel Speed
A properly adjusted travel speed typically produces a bead width about 2 to 3 times the diameter of the electrode. For a 1/8 inch (3.2 mm) electrode, the bead should be roughly 1/4 to 3/8 inch wide. The ripple pattern should be evenly spaced, like a consistent stack of dimes. Slag should release cleanly behind the weld puddle.
| Electrode Diameter | Target Bead Width (2x) | Target Bead Width (3x) |
|---|---|---|
| 3/32 inch (2.4 mm) | 3/16 inch (4.8 mm) | 9/32 inch (7.2 mm) |
| 1/8 inch (3.2 mm) | 1/4 inch (6.4 mm) | 3/8 inch (9.5 mm) |
| 5/32 inch (4.0 mm) | 5/16 inch (8.0 mm) | 15/32 inch (12.0 mm) |
Bead width targets for common electrode diameters. Adjust travel speed to stay within the 2x to 3x range. These are starting guidelines – your joint configuration, position, and electrode brand may require adjustment.
Travel Speed Too Fast
Moving the electrode too quickly produces a narrow, crowned bead with a peaked profile. Undercut forms at the weld toes because the arc does not stay in one spot long enough to fill the edges. Cold lap (lack of fusion at the toes) is another risk – the base metal does not reach melting temperature before the puddle moves on. The ripple pattern becomes erratic and pointed.
Observe the weld puddle as you travel. If the puddle narrows or the arc appears to burn ahead of the puddle, your speed is too high. Slow down until the puddle maintains a consistent width.
Travel Speed Too Slow
Moving too slowly produces a wide, flat bead with excessive reinforcement. The puddle grows too large and slag can roll ahead of the arc, becoming trapped under the solidifying metal. Ripple spacing is tight and irregular. The bead may appear washed out or “puddled out” with poor edge definition.
If the puddle piles up or slag flows over the front of the arc, your speed is too low. Speed up until the puddle trails smoothly behind the arc.
Travel Speed and Amperage Interaction
Higher amperage (within the manufacturer’s range) can sustain a faster travel speed for the same level of penetration. Lower amperage requires slower travel to maintain fusion. The right approach is not to target a fixed inches-per-minute number – adjust your speed to maintain the 2x to 3x bead width target, then fine-tune from there. Larger diameter electrodes produce wider beads at the same travel speed, so bead width targets are always relative to electrode diameter.
Rod Angle: Direction, Work Angle, and Travel Angle
Rod angle has three dimensions that you control simultaneously. Each affects bead shape, penetration, and how well slag separates from the weld.
Drag Angle (Travel Angle)
In flat and horizontal positions, tilt the electrode back 5 to 15 degrees from perpendicular, opposite the direction of travel. This is the drag (or pulling) angle. It directs arc force into the weld puddle for penetration and keeps molten slag behind the arc where it can float to the surface and solidify without being trapped.
Electrode-specific notes: E6010 and E6011 work well with a slightly more pronounced drag angle (10 to 15 degrees) to support the whip-and-pause technique. E7018 runs well with a steady 5 to 10 degree drag and minimal electrode manipulation.
Here is how you can visualize the drag angle. Imagine the electrode standing straight up from the plate at 90 degrees. The direction of travel is forward, to your right. Tilt the top of the electrode back to your left by about the width of two fingers held at the top of the rod. The electrode tip now points slightly forward into the weld joint. This 5 to 15 degree tilt is the drag angle.
Too much drag (excessive lean beyond 15 degrees) pushes the arc force away from the base metal. Penetration becomes shallow, the bead widens, and slag rolls ahead of the puddle. Too little drag (near perpendicular) directs the arc force straight down. Penetration becomes deep and narrow, and you have less control over the puddle.
Push Angle
Vertical up welding typically uses a slight upward push angle of 0 to 15 degrees from perpendicular, combined with either a weave or stringer bead technique depending on electrode type and joint. The electrode tilts upward in the direction of travel, pushing the puddle upward against gravity. Vertical down welding uses a slight drag angle of approximately 5 to 10 degrees downward.
Work Angle
Work angle is the angle of the electrode relative to the joint itself. For a fillet weld (a T-joint or corner joint), a common work angle is approximately 45 degrees, bisecting the 90 degree joint angle. For a groove weld on flat plate, the work angle is approximately 90 degrees (perpendicular to the workpiece surface), adjusted for bevel geometry.
Wrong work angle causes uneven leg lengths in fillet welds, lack of fusion on one side of the joint, and undercut on the higher side. If your bead is not centered in the joint or one edge is higher than the other, check your work angle first.
Common Beginner Angle Mistakes
The most common mistake is holding the electrode perpendicular to the workpiece with no drag angle. This makes it harder to control the puddle and increases the chance of slag entrapment. Another common issue is an exaggerated drag angle of 30 degrees or more, which causes shallow penetration and slag rolling ahead of the puddle. Beginners also tend to fix their work angle and not adjust as the joint position changes along a long weld.
Remember that these angles are starting points. Verify angle recommendations in your electrode manufacturer’s documentation and your project WPS.
Bead Patterns: Stringer vs. Weave
The fourth technique variable is how you manipulate the electrode along the joint – whether you run a straight stringer bead or use a side-to-side weave pattern.
Stringer Beads
A stringer bead is a straight drag with no oscillation. The electrode moves in a straight line along the joint at a consistent speed. Stringer beads produce a narrow weld, typically up to 2 times the electrode diameter. They are simpler to execute and are preferred in code-critical applications.
Stringer beads are used for root passes, thin materials, narrow grooves, and any application where the weave width would exceed code limits. Beginners should master the stringer bead first before moving to weave patterns.
Weave Beads
A weave bead uses side-to-side oscillation of the electrode to create a wider deposit. The welder moves the electrode across the joint width while traveling forward. Several weave patterns exist:
– **Crescent weave:** The electrode moves in a crescent or half-moon pattern, pausing briefly at each edge to ensure fusion, then moving quickly across the center. This pattern provides good edge fusion and is common for vertical up welding. – **Zig-zag weave:** The electrode moves straight side to side with no pause. Faster than the crescent weave but may produce less fusion at the edges. Suitable for filling wide grooves in flat position. – **J-weave:** The electrode traces a J-shaped or teardrop motion. This pattern is effective for vertical up welding because the puddle is supported by the solid metal below it.
AWS D1.1 limits weave bead width to a maximum of 3 times the electrode diameter for prequalified WPSs. Welders should verify the specific code limit that applies to their work. If the joint is wider than this limit, use multiple stringer beads (stringer layers) instead of a single wide weave pass.
When to Stringer vs. When to Weave
Use stringer beads for root passes, thin material, code-critical welds where weave width would exceed the 3x limit, and narrow grooves that can be filled in a single pass. Use weave beads for filling wide grooves, vertical up welding where the weave supports the puddle, bridging variable gap conditions, and increasing deposition rate on larger joints.
Whip-and-Pause Technique
The whip-and-pause technique is required for E6010 and E6011 (fast-freeze) electrodes. Move the electrode forward along the joint (whip) with a slightly longer arc to melt the base metal, then pause briefly to allow the puddle to solidify and the slag to freeze. The characteristic “stack of dimes” appearance on 6010 welds comes from this advance-and-pause rhythm. During the whip, the arc is longer (about 1/8 to 3/16 inch). During the pause, the arc shortens to normal length. This technique is specific to fast-freeze electrodes – do not use whip-and-pause with E7018 or other low-hydrogen electrodes.
Amperage Adjustment for Technique
Amperage is not a standalone setting. It interacts directly with the four technique variables. Understanding this interaction helps you dial in your welds more efficiently.
How Amperage Affects Technique
Higher amperage (within the manufacturer’s recommended range) produces deeper penetration, a wider bead, and the ability to sustain faster travel speed. The arc feels more energetic and stiff. Higher amperage requires good arc length control because the arc column is longer – you need to maintain proper arc length or risk undercut and spatter.
Lower amperage (within the recommended range) produces shallower penetration, a narrower bead, and requires slower travel speed to maintain fusion. The arc feels softer. If you run low amperage and do not adjust travel speed, you risk lack of fusion.
Starting Amperage Ranges by Electrode Diameter
These are general starting ranges. Always consult the specific electrode manufacturer’s data sheet for the product you are using.
| Electrode Diameter | General Amperage Range |
|---|---|
| 1/16 inch (1.6 mm) | 20 to 40 amps |
| 5/64 inch (2.0 mm) | 25 to 60 amps |
| 3/32 inch (2.4 mm) | 40 to 100 amps |
| 1/8 inch (3.2 mm) | 75 to 180 amps |
| 5/32 inch (4.0 mm) | 110 to 250 amps |
The actual amperage you use depends on the electrode brand and product line, the joint configuration, the welding position, and your personal technique. Start in the middle of the manufacturer’s range. Run a practice bead on scrap. Adjust upward if you need deeper penetration or want to travel faster. Adjust downward if you are welding thin material or need a smaller puddle. Fine-tune arc length at the new amperage setting.
Electrode-Specific Technique Quick-Reference Table
The following table summarizes technique characteristics for common stick electrodes. All values are starting points. Amperage ranges are diameter-dependent and manufacturer-specific – this table shows technique characteristics only.
| Electrode | Technique Style | Arc Length | Travel Angle (Flat) | Typical Polarity | Notes |

Putting It All Together: Running a Good Bead
Good technique is the result of integrating all four variables at once. Here is a practical routine to follow on every weld.
Pre-Weld Setup Checklist
- Select the right electrode for the job (base metal thickness, joint type, position)
- Set amperage in the middle of the manufacturer’s range for your electrode diameter
- Confirm polarity (DC+ for most electrodes; check the electrode data sheet)
- Clean the base metal – remove rust, mill scale, oil, paint, and moisture
- Check joint fit-up – consistent gap and alignment
- Put on your PPE: welding helmet (correct shade), leather gloves, flame-resistant long sleeves, leather boots
- Position yourself for comfort and clear visibility of the weld puddle
- Clear combustibles from the work area (35 feet minimum per OSHA)
Striking the Arc
Use a scratch start (like striking a match) or a tap start. Beginners should practice striking the arc on a scrap plate first, not on the actual joint. Once the arc is established, immediately settle into the correct arc length. Listen for the crackling sound.
Technique Integration Sequence
1. Establish correct arc length. Listen for the steady crackling sound. If you hear hissing or popping, adjust before you start traveling. 2. Set your drag angle. In flat position, tilt the electrode back 5 to 15 degrees in the direction of travel. 3. Begin traveling at a steady speed. Watch the bead width. It should be approximately 2 to 3 times the electrode diameter. 4. If the bead is too narrow or crowned, slow down your travel speed. If the bead is too wide or flat, speed up. If the bead is not centered in the joint, check your work angle and aim point. 5. At the end of the weld, break the arc cleanly with a slight backward motion or by lifting the electrode to avoid a crater defect.
Visual Indicators of Proper Technique
– Consistent bead width (2 to 3 times electrode diameter) – Even ripple pattern with uniform spacing – Clean slag release that lifts off easily or is self-releasing – No undercut at the edges of the bead – Proper reinforcement – slightly convex, not flat or humped – No porosity or visible pinholes
Common Beginner Troubleshooting
When a weld does not look right, use this table to identify the probable cause and the technique adjustment needed.
| Symptom | Probable Cause | Technique Adjustment |
|---|---|---|
| Excessive spatter | Arc too long | Shorten arc length |
| Porosity (pinholes in bead) | Arc too long; contaminated base metal | Shorten arc; clean base metal |
| Undercut at edges | Travel speed too fast; arc too long; wrong work angle | Slow down; shorten arc; adjust angle |
| Slag entrapment | Travel speed too slow; wrong drag angle | Speed up; increase drag angle |
| Narrow, crowned bead | Travel speed too fast | Slow down |
| Wide, flat bead | Travel speed too slow; amperage too high | Speed up; reduce amperage |
| Arc sticking to workpiece | Arc too short; amperage too low | Lengthen arc; increase amperage |
| Inconsistent bead width | Unsteady hand; varying travel speed | Practice maintaining steady speed; brace yourself |
| Arc blow (arc wandering) | Magnetic field; DC welding | Use AC if possible; reposition ground clamp |

Remember
Technique improvement comes from practice on scrap. Run beads, inspect them, adjust one variable at a time, and observe what changes. Nobody runs perfect beads on the first try. Consistent practice builds muscle memory and the ability to read the weld puddle in real time.
When to Check the Manufacturer Manual
The technique settings in this article are starting points. They reflect general recommendations from Lincoln Electric, Miller, ESAB, Hobart, and AWS standards. However, your specific electrode brand and product line may have different recommended arc lengths, amperage ranges, polarity, or technique requirements.
– Manufacturer amperage ranges vary by electrode brand, diameter, and product line. Always check the electrode data sheet that came with the product you bought. – Electrode technique characteristics (arc length, angle, polarity) may have specific requirements for certain products. A different brand of E7018 may recommend slightly different settings than what is shown here. – AWS D1.1 and other applicable codes may impose additional technique requirements for prequalified WPSs or welder performance qualification tests. – The WPS (Welding Procedure Specification) for any code work specifies the technique parameters that must be followed. Do not substitute general guidance for a project-specific WPS. – For structural or code-critical welding, have your welds inspected and qualified per the applicable standard. Technique that produces acceptable beads on scrap may not meet code acceptance criteria without proper qualification testing.
Final Note
All arc length, angle, amperage, and bead width values in this guide are starting points. The electrode manufacturer’s data sheet and your project’s WPS are the final authorities. For electrode selection and storage guidance, see our Stick Welding Electrode Guide.
