Abstract
A system is provided for use in a microprocessor controlled controller for a resistance welding machine for calculating the RMS value of the welding current so as to provide a closed loop control of the RMS current in order to eliminate the effect of variations in load and line voltage on the welding current and to provide a constant welding tip temperature in the presence of such variations.
