What is Welding Cable
Welding cable is the electrical conductor for the welding current. It consists of a series of fine copper strands wrapped inside a non-conductive, durable jacket (typically some type of synthetic or natural rubber of various colors). The fine copper strands give welding cable more flexibility than other types of electrical conductors and the insulating jacket is designed to hold up to repeated movement over rough surfaces. As the current level increases (measured in amperage or amps), the diameter of the welding cable and resulting cross sectional area of the copper stranding needs to increase.
Welding Cable Construction:
Conductor:
6 AWG through 500 kcmil fully annealed stranded
bare copper Class K
Jacket:
Premium-grade 90ºC EPDM, black or red
Temperature range: -40ºC to +90ºC
