Welding cable, All Sizes
Fine stranded copper cable with a flexible rubber jacket, for welder leads, battery banks and inverters. NEC Article 630 covers welders, their supply conductors and, in Part IV, how welding cable is installed. No NEC table sizes the leads; they are sized from the welder maker's chart.
We list 11 sizes of Welding cable, from 6 AWG to 500 kcmil. All of them are priced online, from $1.93/ft. Sold by the foot in whole feet from 50 ft, or on standard spools and coils. Up to 2 colors are listed per size. Each size has its own page with the price for every color and length, the date an order placed now ships, and the full specifications.
