POWER FEEDER FOR RESISTANCE WELDING GUN

摘要

PURPOSE:To allow the free attachment and detachment of the connection of a power source and a gun body to smooth oscillation of the resistance welding gun by providing a power feed part which is terminal-connected to a power source side and a connecting means which is freely attachable and detachable to and from the terminal of the body side to the power feeder of the welding gun. CONSTITUTION:The power receiving terminal 104 on the gun side which is displaced according to the oscillation of the resistance welding gun 100 and the terminal 74 on the power source side are connected freely connectably by using the connecting means 58 which is driven by an actuator. The connection of the terminal 104 and the terminal 74 is released by the operation of the connecting means 58 to put the gun 200 into the free state when the welding ends. The oscillation operation of the gun is thus smoothed without being hindered by a power feed cable.
