Welding Cable

What are Class K welding cables?

Class K welding cables are standard welding cables constructed as single-core insulated cables in a relatively large-diameter designed to be used to connect welding machines, welding electrodes, ground clamps, and automated welding heads. Cables usually, but not always, have different colors so users can distinguish between the live wire and the ground wire. Welding cables have great flexibility and are soft but have strong abrasion- and oil-resistant insulation. Class K welding cables are rated at 600 volts. These welding cables come in a range of colors including red, black, orange, yellow, green, and blue.
