Which welding technique increases penetration by pointing at the weld bead and dragging away from it?

Penetration is driven by where the heat of the arc is concentrated and how the puddle sits in the joint. When you pull the gun so the contact tip is aimed at the weld bead and you drag the arc away along the seam, the heat is directed deeper into the root. This causes more fusion into the base metal, giving greater penetration and a more pronounced root. Pushing the gun forward tends to place heat more on the surface and along the puddle, producing a wider bead with shallower penetration. So, the pull motion—aiming at the bead and dragging away—is the technique that increases penetration.
