ABSTRACT:
The utility hoses of a welding gun are connected to the inner body of an insulative-sleeve enclosed utility station through which a consumable electrode feeds to the gun. The inner body establishes communication of the gun hoses with sources for said utilities and utilizes couplers which quickly connect and disconnect both the gun hoses from the station and the station from the supply sources for the utilities required by the gun.
