Abstract The body of a stud welding tool is made of a plurality of separate parts. The main housing of the tool thereby can be employed for different applications without the necessity of designing and molding a different housing for each application. The handle of the welding tool body is made of several portions which enable an operator to have access to the interior more readily and more easily. The welding tool also has an internal component through which current is supplied to a chuck of the tool, and which causes fasteners to be transferred from a point behind the chuck into the chuck. The component is compact and relatively maintenance free. In particular, the welding tool can be substantially shorter and lighter than those of a like nature heretofore employed.
An arc welding tool body comprising a main housing and a front wall member, said housing having a hollow interior and a mating surface at an end portion thereof with an opening extending through said surface and communicating with the interior of said housing, and said mating surface having locating pins extending from predetermined positions thereon, the front wall member having a surface to be mated with the mating surface of the main housing and the surface having counterbored recesses formed therein, each of said pins having a threaded recess therein, said pins extending into counterbored recesses when the main housing is engaged against the front wall member.
