Claim:
A welding gun body comprising: an enclosure forming an exterior surface of the body, the enclosure configured for both receiving a welding wire and a power source and directing the same toward a torch, the enclosure extending longitudinally between first and second enclosure ends; the first enclosure end having an outer surface through which a wire-receiving aperture extends in a longitudinal direction from the first enclosure end to an internal non-circular first block-receiving cavity, the first block-receiving cavity shaped to selectively receive a first removable block, the first removable block extending inwardly along a longitudinal axis with an outer profile generally shaped to closely match the non-circular profile of the first block-receiving cavity, said first removable block comprising a welding wire conduit positioned therethrough, said conduit further accommodating a shielding gas; the non-circular first block-receiving cavity of the enclosure extending axially in a longitudinal direction with a non-circular profile to a cable-receiving cavity within the housing, the cable-receiving cavity extending longitudinally toward the second enclosure end, said cable-receiving cavity comprising at least two cable conduits positioned within said housing; the second enclosure end including a wire and shielding gas exit aperture, said second enclosure end in proximity to a second non-circular block-receiving cavity; a removable second block positioned within the second block-receiving cavity, the removable second block extending axially inwardly with an outer profile generally shaped to closely match the non-circular profile of the second block-receiving cavity; the second block having opposed ends, said second block also having a pair of wire-receiving and wire-exiting apertures extending axially between the opposed ends of the second block, the first block end being arranged generally adjacent the aperture of the first enclosure end; the second block being arranged generally adjacent the aperture of the second enclosure end, said second block further receiving two or more power cable-receiving apertures in addition to the wire-receiving aperture each of the two or more power cable-receiving opening form a socket for receiving a pipe-spigot of a corresponding power cable.
