A stud welding gun has a forepart which includes the delivery end of an automatic stud-feeder and is secured to the housing by a quick releasable joint so as to be readily replaceable by another forepart supplying a stud of different size. The gun includes a pneumatic piston and piston rod which serves to push a stud into the collet after delivery to the gun. The piston rod is detachable from the piston and means is provided for locking it in the forepart so that it is replaced into the forepart for studs of different size.
