Abstract: A stud welding gun for alternatively welding studs of a first and second length to base members. The gun includes a stud feed member for moving a stud toward a stud holder. The gun further includes at least two stud cartridges each having a plurality of studs in side by side array and opposed end walls extending between first and second side walls. A first cartridge has end walls spaced a distance equal to studs having the first length. A second cartridge has end walls spaced a distance equal to studs having the second length. At least one of the side walls of each cartridge extends to a pre-determined overall length. A housing is adapted to receive the cartridges placing the studs in the path of the stud feed member. The gun includes a stud mover that sequentially moves the studs into the path of the stud feed member.
