  • Patent number: 5844201
    Abstract: A welding torch apparatus for use with conventional arc welding torches which have a gooseneck, a gas nozzle with an interior and a longitudinal axis, a first passageway for supplying of both a welding wire to a tip, and gas mixtures to a gas diffuser. The welding torch apparatus comprises a second passageway for selectively introducing into the interior of the gas nozzle, gas mixtures which by-pass the first passageway, so that contact is avoided between gas mixtures passing through the second passageway and gas mixtures and welding wire passing through the first passageway, until the gas mixtures and welding wire enter the interior of the gas nozzle, and wherein gas mixtures passing through the first passageway do not contain oil additions.
