Generally classified as a type of industrial power cable, welding cable is mainly used to power the secondary circuit of electric arc-welding generators. Being more flexible than THHN wire, the cable is made from copper wire surrounded by a protective casing that is defiant to flame, heat, oil and abrasions, among other things.

As far as the materials are concerned, welding cables comes in different grades based on durability and strength. In general, it is used as a secondary cable to power the electrode of welding device. Circumspectly marooned to allow for maximum flexibility, the wiring is usually made from copper and the covering of the welding wire may be made from Neoprene or EPDM rubber, short for ethylene propylene diene M-class rubber. Two different cables are attached to electric arc-welding tool, one to power the device and the other for secondary circuit electrode itself.

Welding power cable properties: In view of the fact that welding cable is used for coarse conditions where it can be open to the elements like heat, sparks, weight and possibly accidents, it is put up to be durable. Made to bear up flame, sparks, heat, abrasions, oil, tar and grease, the outer covering of Neoprene or EPDM rubber open to all these elements, can still sustain while letting you use in both wet and dry conditions. They are intended to function at some specific rate i.e. the wiring is rated at 60, 75 or 90 degrees Celsius, indicating what temperatures it can handle, and at 100 or 600 volts. Nevertheless, welding cables are made to function beyond these limits as well.
