ABSTRACT:
A power supply circuit including a multivibrator and a power output module. Drive signals are provided at low power level and an FET stage is used to provide a high wattage output to operate the power output module. The power output module provides machining power pulses to the gap through a plurality of series resistors so that peak current can be regulated in the module itself.
