ABSTRACT:
An apparatus for joining a threaded free electrode section with a threaded fixed electrode section for use in electric arc furnaces. The apparatus comprises a driver and a coupler with a plurality of pawls to grip the free electrode section and turn it in one direction. After the driver and coupler pass through a range of motion causing the free electrode to turn in the same direction, they reverse direction, with the pawls releasing the free electrode so that the free electrode does not reverse direction, and the driver and coupler return to the original position in a ratchet-like action.
