Abstract

A process is disclosed for generating a sinusoidal, periodically variable welding current with a high power density for a multipoint resistance welding machine powered by a monophase alternating current. The welding current is generated from a three-phase mains voltage source by means of a pulse width modulated current inverter circuit and the frequency of the welding current is set at a higher level than the frequency of the mains voltage source.
