<p>A stud welding system which utilizes a stud welding gun capable of interacting with the stud welding power supply and welding controller in a manner such that the extent and rate of lift, duration of holding and lift position and extent and rate of plunge can be independently varied and controlled over a wide range. The interactive stud welding gun utilizes a stepping motor in the stud welding gun which actuates the gun shaft assembly and its associated chuck carrying the stud to be welded. A transducer associated with the stud welding gun senses the position of the gun shaft assembly relative to the gun body and provides a reference signal therefor. A microprocessor controlled interactive gun control responds to the signal from the transducer to determine gun shaft assembly position and generates an energization signal for the stepping motor to drive the gun shaft between lift, hold and plunge positions preprogrammed into the interactive gun control.</p> |
