Abstract
A weld gun including a frame structure, a weld arm structure mounted on the frame structure, and an electrode mounted on the weld arm structure. The rear end of the electrode is circular and fits in a circular aperture in the weld arm structure. A radially projecting tab on the electrode fits into a groove in the weld arm structure. The groove opens axially in an end face of the weld arm structure and radially in the aperture in the weld arm structure so that both the axial and angular disposition of the electrode relative to the weld arm structure may be established by simply inserting the tab on the electrode into the groove of the weld arm structure to seat a leading end shoulder on the tab against a blind end shoulder of the groove.
