ABSTRACT:
A stud welding gun 1 has a collet 4 to hold a stud, a piston to push a stud out to the collet, and a feed pipe to automatically feed studs one by one. A stud receiving member 15 to receive and store studs is provided between the collet and the stud feed pipe and the stud receiving member is provided with at least two stud receivers 16. Each stud receiver is capable of moving between a first position in which it receives a stud and a second position which continues to the collet and in which a stud pushed out by the piston is held by the collet, and when a stud receiver 16 is in the second position, another stud receiver is in the first position. By this, the receiving of a stud is carried out simultaneously with the loading of a stud to reduce the working time.
