To create clean, perfect weld beads with a wire-feed welder, try this tip from Club member Ken Berkey of West Newton, Pennsylvania. Clamp a small section of copper stock at each end of the intended joint. When you’re ready to start welding, begin the weld bead on the copper, working your way toward the actual metal workpieces. Continue the weld past the workpiece, running back onto the copper, all the while maintaining a smooth, steady movement. Ken says copper is ideal for this purpose because it draws heat away from the welding wire, and the bead of molten metal won’t stick to it.
