Abstract
A device for feeding electric power to a roll-like revolving electrode in an electrical resistance welding machine includes a feeder rotor provided in a shaft formed integrally with a revolving electrode and a feeder plate extending in the moving direction of the revolving electrode and disposed in contact with the periphery of the feeder rotor. The periphery of the feeder rotor is electrically coupled to the electrode surface of the revolving electrode, and the feeder plate is connected to a power supply. Consequently, the electrode surface of the revolving electrode is electrically coupled to the power supply.
