450/750V Welding Cable

Welding cable is used in welding tools, usually as a secondary cable to power the electrode of the weldingmechanism. The welder will attach two different cables to his electric arcwelding tool, one cable to power the device and a secondary circuit for the electrode itself. Most arcwelding generators have systems that require this secondary power source for operation. While the welding cable does not provide primary power for the generator or allow it to function, it does allow the electrode to function.

2. Materials of Electric Welding Cable
Welding cable comes in various grades depending on durability and strength. The wiring itself is usually made from copper, carefully stranded to allow for maximum flexibility. The covering of the welding wire may be made from Neoprene or EPDM rubber, short for ethylene propylene diene M-class rubber.

3. Properties of Electric Welding Cable

Because welding cable is used for rough conditions where it can be exposed to heat, sparks, weight and possibly accidents, it is constructed to be durable. The outer covering of Neoprene or EPDM rubber is made to withstand flame, sparks, heat, abrasions, oil, tar and grease while letting you use it in both wet and dry conditions. Inside, the wiring is rated at 60, 75 or 90 degrees Celsius, showing what temperatures it can handle, and at 100 or 600 volts. Welding cables are made to function beyond these limits, and in this case the parameters are printed on the cable itself.

4. Considerations

Because of its flexibility and durability, welding cable has been used for electrical systems, such as entertainment lighting systems or sound setups. However, welding cable is not made for these purposes and is not reliable. It can lead to malfunctions or possibly dangerous electrical accidents. For smaller, amateur uses, battery cable and welding cable are both considered possible options.
