What drive-roll shape is designed for soft welding wires?

Explanation:
Drive-roll shape affects how the wire is gripped and fed toward the gun. Soft wires deform easily, so they need a groove that supports them without biting or pinching. A U-shaped drive-roll provides a rounded cradle that distributes pressure evenly around the wire, reducing deformation and preventing slips as it feeds. This yields smoother, more consistent feeding for soft wires. In comparison, a V-shaped groove tends to pinch or indent a soft wire, while a flat groove doesn’t cradle the wire well, leading to irregular feeding. So for soft welding wires, the U-shaped drive-roll is the best design.
