A welding gun for a capacitor discharge bolt welding device includes a thrust unit axially movably positionable within the housing. A collet chuck is fitted on the forward end of the thrust unit and holds individual bolts in position for the welding operation. A stop threadedly secured within the housing is adjustably positionable in the axial direction of the thrust unit relative to the housing for selectively adjusting the lead between the forward end of a bolt held in the collet chuck and the forward end of the supporting feet extending axially from the forward end of the housing.
