Push vs Pull Technique — What It Is and Why It Matters
Push technique (forehand) moves the torch with the electrode pointing backward, away from the direction of travel — the torch pushes the puddle forward. Pull technique (backhand, drag) moves the torch with the electrode pointing forward, into the direction of travel — the torch drags behind the puddle.
In MIG welding, pushing generally produces a wider, flatter bead with less penetration and better gas coverage (the gas leads the puddle). Pulling produces a narrower, more convex bead with deeper penetration. Many welding instructors teach pushing as the default for MIG steel welding because the better gas coverage reduces porosity risk.
In stick welding, pulling (dragging) is the standard technique — the slag trails behind the arc and does not interfere with the weld pool. In TIG welding, pushing is the more common technique, as it allows the welder to see the puddle ahead of the torch and provides better gas coverage to the cooling weld. Both techniques produce acceptable welds when executed properly; the choice depends on the process, joint configuration, and desired penetration profile.
Frequently Asked Questions
Should I push or pull with MIG?
For general MIG welding on steel, many welders and instructors recommend pushing for better gas coverage and smoother bead appearance. Pulling provides deeper penetration, which some prefer for thicker material and fillet welds. Both techniques produce acceptable welds — the more important factor is consistency and comfort.
Why do you drag stick welding?
In stick welding, the slag produced by the flux coating must be kept behind the arc, not ahead of it. Pulling (dragging) naturally deposits slag behind the weld pool where it solidifies over the fresh weld. Pushing stick welding pushes slag into the puddle, risking slag inclusions and irregular bead appearance.
