A power cable for use with welding apparatus for conveying power and cooling fluid from a welding machine to a welding torch. The cable includes an outer flexible conduit disposed about a flexible electrical conductor, a pair of end fittings operatively connected to the ends of the conduit and an electrical conductor for securing the power cable between the welding torch and welding machine in fluid and electrical communication therewith. The flexible conduit includes an inner tube portion formed of a flexible non-conductive rubber compound, a protective cover layer comprised of a plurality of threads braided or woven about the inner tube portion and a thin coating of a heat and wear resistant material such as polyurethane disposed over the braided or woven threads for bonding the protective cover layer to the inner tube portion, rendering the power cable heat and wear resistant without adversely affecting the flexibility thereof.
