Abstract: A stud welding apparatus includes a power supply and a stud welding tool having a welding head portion and a cable receiving portion. A composite cable having first and second ends is coupled at a first end to the stud welding tool at the cable receiving portion and to the power supply at the second end of the composite cable. If the stud feeder is present, the second end of the composite cable can be coupled to the stud feeder. The composite cable includes a conductor having no individual electrical isolation and at least one control lead electrically isolated from the conductor. The conductor and the at least one control lead are surrounded by an outer non-conductive layer.
