ABSTRACT:
Pressure applying device for resistance welding which includes a pair of two gun arms having an electrode tip at two opposed ends of the arms, a flexible supporting means connecting said two arms, an actuator provided between said two arms, and a link mechanism connecting said two arms to define movement of the electrode tip. According to this invention, the operation of said actuator to pull the gun arm allows the electrode tips in the open position as well as the supporting means accumulating resilience. And, the reverse operation of said actuator can provide an elastic force by said flexible supporting means acting on the pieces between the electrodes, in addition to the welding pressure by the actuator.
