6 OPERATING PRINCIPLE OF WELDING THREADED STUD BOLTS WITH CONTACT POINT START-
UP (FIG. 3)
The stud bolt is inserted in the clamp X (phase 1), then positioned and pressed with its start-up contact directly
against the surface of the sheet metal to be welded (phase 2). The spring of the gun presses the stud bolt against
the metal, the start command begins sending current which melts the start-up contact, and the electrical arc is
propagated along the entire surface of the stud bolt (phase 4) pushed against the metal surface. The molten metal
solidifi es, thereby welding the stud bolt (phase 5).
The gun must be extracted in perfect alignment with the bolt to avoid deforming the clamp, and thus ensuring its long
life-span (phase 6).
