Abstract

Tip of the welding torch is surrounded by a cuff which forms with the workpiece a space in which the screen gas accumulates to expel the water and enable an arc to be struck. Specifically, te cuff may form a bell surrounding the tip and ending in a flexible skirt, and this may be shaped to fit directly against the workpiece.
