ABSTRACT:
A multi-operator grid system for stud welding is disclosed which works in conjunction with a microprocessor controlled single stud welding power supply. The multi-operator grid system utilizes a single multiplexer interconnected with a plurality of weld stations each of which includes an isolator, hand held terminal and stud welding gun. Each hand held terminal working through the multiplexer can program the microprocessor stud welding supply for parameters of pilot arc and welding current energy and cycles. The microprocessor controlled stud welding supply, through the multiplexer, provides read outs to printers and to the hand held terminals of the resultant stud welding parameters such as total welding energy, weld current and the like. The multiplexer, working in conjuction with the microprocessor controlled stud welding supply and the isolators, controls the pilot arc and weld current to the stud welding guns as well as the plunge thereof.
