Abstract
PURPOSE: To obtain always a good and uniform welding effect, by detecting a differential value between a welding interelectrode voltage and a reference value and by leading out the firing angle operation quantity of a switching element corresponding to this differential value from a program produced preliminarily.
CONSTITUTION: An interchip voltage at a constant time after the initial stage of electric conduction is detected, and this value is compared with a reference value to detect their differential value. Meanwhile, this differential value and the operation quantity of a switching element are programmed for every firing angle of the switching element preliminarily. This program is used to move the firing angle of the switching element from the detected differential value forward and backward, thereby changing a welding current. This control operation is performed in every one cycle to cause the interchip voltage to approach the set reference value and imitate it. By this control method, a unifrom welding effect is obtained to improve the welding quality even if welding conditions are changed.
