An automatic welding stud feeder for a stud welding gun 10 comprises a magazine 40 provided at the upper side of the gun and a transfer lever 26 for transferring the respective foremost welding stud in the magazine 40, by pivotal movement through a substantially quarter-circular path, to an operating position in front of a welding electrode 14. The driving force for the transfer lever 26 is generated by springs 24 which are compressed when the welding electrode 14 with the stud 43 is pushed against the workpiece 50. In its rest position, the transfer lever 26 is locked by a catch 36. The catch 36 is actuated by a release lever 35 which is operated with the thumb of the same hand that holds the welding gun.
