Welding cable is a flexible, durable electrical cable that supplies power to the secondary circuit of electric welders, which controls the electrode that releases the charge needed for the welding process. Also called an electrode cable, it is commonly used in manufacturing environments to power resistance welding and arc welding equipment, or to replace or repair damaged cable. It has a single, finely stranded conductor wrapped in a nonconductive rubber jacket that is resistant to heat, burns, sparks, and abrasions. The fine copper strands give welding cable more flexibility than other types of electrical wire, and the insulating jacket is designed to hold up to repeated movement over rough surfaces.
