Welding cable is a portable cord with a single conductor that is finely stranded for flexibility. It is offered in sizes ranging from 6 AWG to 500 MCM. Oftentimes referred to as grounding cable, it features a single bare annealed copper conductor that is finely stranded which provides the flexibility that welding cable is known for.
Welding cable is typically used because of its flexibility and versatility which result from its construction of finer strands of copper and EPDM or neoprene rubber jacket. In fact, it is generally more flexible than electrical wires or power cables. Depending on the manufacturer, welding cable has a temperature rating of -50℃ – 105℃ and when put to the test, many of these cables will withstand exposure to grease, oil, and water as well as cuts, tears, and abrasion.
