ABSTRACT:
A kit for adapting tungsten-inert-gas welding torches of conventional design to use high amperage current. This comprises an internally and externally screw-threaded tube of highly conductive heat-resistant material which is designed to screw onto a cable housing terminal on the torch body, an insulating gasket which seats against an external shoulder of the torch body, and an insulating sleeve which fits over the internally and externally screw-threaded tube in place on the cable housing terminal, and seats against the gasket. This combination provides gripping means for the operator of the welding torch while dissipating the heat generated by the high operating current.
