Abstract
A rotating power connection for connecting an electrical supply power cable to an electric welding torch body is provided. In the rotating power connection, the mechanical load is carried by steel bearings, and the electric load is carried by multi-contact, spring loaded fins made out of highly conductive materials or coatings. In some examples, a rotating power connector is affixed to a torch before the power connection to a wire feeder. The rotating power connector advantageously allows for rotation of the welding torch relative to the unicable while providing continual electrical connection at the high current levels employed in welding applications.
