A stud retaining collet enables a welding gun successively to receive and hold in welding position studs or the like having circumferentially enlarged head portions. The improved collet, especially useful in arc welding, has a base which, with an associated mechanism of the gun, effects non-spurting stud retention against forces feeding the studs and also is able to conduct the welding current to the stud. |
