Abstract
PURPOSE: To perform optimization controlling during welding and homogenize the welding quality by detecting the voltage between electrode tips during welding, determining the desired welding effective current value from the integrated value thereof then desired firing angle, and converting the firing angle of a control rectifier element to said value.
CONSTITUTION: The voltage between electrode tips 3, 3' of a resistance welding machine incorporating a rectifier element 1 for controlling welding output is detected, and the integrated value between half cycles of every cycle up to an arbitrary set electricity conduction cycle is determined with the 1st integrating circuit 6. Next, this 1st integrated value is integrated with the 2nd integrating circuit 7 from 1 cycle up to an arbitrarily set electricity conductive cycle. This 1st or 2nd integrated value is inputted to the 1st function circuit 8, and from the circuit 8, a desired welding effective current value is outputted. Next, a desired firing angle signal is generated by the 2nd function circuit 9 inputted with said effective current value. thence, the firing angle of the element 1 set before the start of the welding is changed to the above-mentioned desired firing angle by a firing circuit 10 receiving said signal.
