ABSTRACT:
A stud welding gun (20) includes a frame (36) which extends outward from a handle assembly (24). A chuck (46) on an outer end portion of the frame holds a stud (22) while the stud is being welded to a base member. A stud supply (60) is connected with the frame (36) and includes a housing (64) which receives a stud retainer or magazine (70) containing a linear array (72) of studs (22) disposed in a side-by-side relationship. The studs (22) are fed from the retainer (70) in the stud supply housing (64) to a receiving location (62). A stud feed member (76) is manually moved from a retracted position to an extended position to sequentially feed studs (22) to the chuck (46). The size of a linear slot (88) in the stud supply housing (64) can be varied to enable retainers (70) containing studs (22) of different lengths to be positioned in the stud supply housing.
