置。 In resistance spot welding, the primary input voltage of the welding transformer and the primary or secondary current of the welding transformer are detected, and these are compared with the set voltage and set current in the control circuit to determine the phase angle of the thyristor. In the resistance welding control device, the initial energization stage where the load resistance of the welded material is unstable is controlled by a constant voltage control method using the primary input voltage of the welding transformer,
A resistance welding control device characterized in that main energization after the middle period when load resistance is stable is controlled by a constant current control method using a primary current or a secondary current of a welding transformer.
