ABSTRACT:
A welding terminal operable to arc weld to a work piece a stud thereafter drive an element prethreaded to the stud. In one embodiment, the welding terminal may be adapted to cooperate with a guide to facilitate engagement with the prethreaded element, and in another embodiment, the welding terminal may have fluting or ribs to grippingly engage a portion of the prethreaded element. The duration of the arc weld and the sequencing of the welding and driving functions both may be automatically controlled. The normal force imposed on the fixed stud portion and the torque imposed on the movable threaded portion may be substantially automatically limited.
