ABSTRACT:
Apparatus for welding studs utilizing a two-wire control is provided. The apparatus includes a stud welding tool capable of welding studs by a drawn-arc technique. A stud welding control circuit and a source of welding power are remotely located from the tool with the difference exceeding one hundred feet in some applications. Heretofore, two wires were required to connect the tool and the control circuit to initiate the welding cycle and two additional wires were required to control movement of the stud during the welding cycle independently of the position of a start switch on the tool after the switch is closed. The present apparatus requires only two wires to both initiate and control the weld cycle. This reduces costs and maintenance and increases reliability and maneuverability of the tool.
