A compact, flexible, lightweight welding gun is provided, including a single outer tubular casing substantially containing all the weld gun components. Concentric disposition of annular fume evacuating passageways between the outer tubular casing and component electrical transmitter elements insulates the external surfaces of the casing from the electrical heat sources within the gun, while cooling gases circulating in the gas passageways promote dissipation of accumulating heat. The improved cooling properties of the gun permit relatively higher levels of current and therefore increased speed of weld bead deposition, while the single conduit structure of the welding apparatus renders it more compact, flexible and lightweight, as well as more maneuverable due to the relatively clean exterior of the gun.

A fume extracting welding gun, through which a consumable electrode wire is fed, comprising: a head portion having a tubular housing, an inner conduit, and a distal end thereof; a control handle portion having a tubular sheath connected to the tubular housing, said inner conduit being disposed within the tubular sheath; a flexible connector portion having a flexible outer tube, a flexible inner conduit, and a proximal end, said flexible outer tube being connected to the tubular sheath and said flexible inner conduit being connected to the inner conduit; first positioning means extending inwardly from the tubular housing for concentrically maintaining the inner conduit within the head portion and defining a first annular fume extraction passageway; second positioning means extending inwardly from the tubular sheath for concentrically maintaining the inner conduit within the control handle portion and defining a second annular fume extraction passageway, said second positioning means including a clip extending between the tubular sheath and the inner conduit; third positioning means extending from the flexible outer tube for concentrically maintaining the flexible inner conduit within the flexible connector portion at the proximal end and defining a third annular fume extraction passageway, said first, second and third annular fume extraction passageways serially extending fully between said distal and proximal ends of the gun and having substantially common radial dimensions, said third positioning means including an elbow having a wire feed adapter, a cylindrical inlet and a cylindrical outlet, said wire feed adapter being connected to the flexible inner conduit, said cylindrical inlet being connected to the flexible outer tube, and said cylindrical outlet extending angularly outwardly from said wire feed adapter; suction means in communication with said cylindrical outlet and the third fume extraction passageway for moving fumes from the distal end of the head portion, through the fume extraction passageways and outwardly from the gun; means for conducting the consumable electrode wire through said wire feed adapter, said flexible inner conduit, and said inner condunits said inner conduit and said wire defining an annular shielding gas passageway; means for conducting a shielding gas into the gun, through the annular shielding gas passageway and outwardly from the distal end of the head portion; and means for conducting electricity into the gun, through said wire feed adapter and the inner conduits, and to the consumable electrode wire at the head portion of the gun.
