Abstract
A primary cable apparatus for a robot welding gun having a cable including a pair of conductors operatively connected to a welding power source, a grounding conductor, a shield wire surrounding the pair of conductors and the grounding conductor and an insulation coating operatively positioned around the shield wire. A first connector is operatively mounted on one end of the cable for connection to the welding power source and includes terminals connected to the conductors. A second connector is provided for detecting a disorder having a terminal operatively connected to the grounding conductor and a terminal connected to the shield wire for detecting damage to the insulation coating of the cable. A disorder detector is operatively connected to the terminals of the second connector and includes a circuit breaker interposed in a welding power circuit which is responsive to an output of the disorder detector.
