A torch cable in which both the electrical connection and the pneumatic connection can be made concurrently in one motion by coupling the end of the torch cable to the exterior of the supply unit. The coupling further includes a quick disconnect feature. The torch cable coupling is simple and inexpensive, using standard off-the-shelf components. The end of the cable comprises various components that are overmolded to form an electrically insulative body, e.g., made of urethane rubber compound. This molded body incorporates strain relief, is water resistant, protects the electrical plug, and stabilizes the electrical contacts. Gas, power and control are combined in one assembly. The pneumatic quick disconnect coupling is used as a latching mechanism for the entire assembly. The torch cable can be disconnected from the supply unit by simply releasing the quick disconnect coupling and then pulling the end of the torch cable away from the supply unit. The pneumatic connector and the electrical plug form keying means by their orientation.
