Claims

[Scope of utility model registration request]

In a device that resistance welds metal members by clamping the metal members to be welded between a pair of electrodes and passing a current between the electrodes, the welding current can be monitored to determine the A weld checker that detects a deterioration state, and an electrode movement that changes the electrode metal member press contact surface from a deteriorated surface to a normal surface by moving the electrode in a direction parallel to the pressure contact surface when the weld checker generates a deterioration state detection signal. A resistance welding device characterized by comprising a mechanism.
