Title: Resistance welding controller
Inventor: SHIROCHI TAKASHI
IPC: B23K11/25
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of heat generation, to shorten an electric current supplying time and to improve the quality of welding by shortening the suspension of welding energy at the time of switching polarity in inverter control AC type resistance welding. SOLUTION: When each current supplying period is started, on-signals of e.g. H level are fed to a switching element having a relevant polarity of an inverter with a controller, and these switching elements are turned on and moreover held in an on-state as they are (step S1). Thus, the current is begun to flow in a primary and secondary sides of a weld transformer and rising in a rapid grade is obtained. In the controller, when current detecting signals <11> from a current sensor reach a set current value 1F for rising the current in the current supplying period (step S3, S4), on-signals are stopped, PWM signals are fed instead of the on-signals, and the switching elements are switching-controlled with a high frequency (e.g. 10 kHz) (step S5-S9).
