ABSTRACT:
The voltage supplied to the welding electrode of a welding system repeatedly and accurately charges an energy storage device by directly sensing the charging voltage across the storage device and comparing the sensed voltage to a reference voltage to produce a control signal and by using the control signal to control the welding system. The charge storage device is charged through the part to be welded to warm the part and improve the weld.
