Abstract
Abstract Cable apparatus for conducting gas and electricity, and if desired, an electrode wire, having at least at one end of the cable means for making a quickly disconnectable connection to connectable means such as a gun or the like that emits electrical current, gas, and electrode wire if desired. Such cable end means, and the gun or other means connected to the cable, are so constructed that when released the gun or the like can be rotated with respect to the cable about the axis of the cable, and then resecured by quickly actuated locking means in a desired rotational position. The gun or other means connected to the cable end means can also be readily disconnected from the cable. Notwithstanding the rotational and quick disconnect and connect features, the gun or other means connected in the cable makes a gastight connection.
