Connection block for integral handle

A welding gun assembly for directing a welding wire toward a workpiece, comprising:

• a torch positioned at a forward portion of the gun;
• a gun body comprising an enclosure extending longitudinally between first and second enclosure ends, the torch being attached to the first enclosure end and the second enclosure end adapted to receive a welding wire cable and two or more power cables;
• the first enclosure end including an aperture extending in a longitudinal direction of the enclosure from an outer surface to an internal block-receiving cavity;
• the block-receiving cavity extending axially in a longitudinal direction with a non-circular profile to a cable-receiving cavity within the enclosure, the cable-receiving cavity extending longitudinally to the second enclosure end;
• a removable block positioned within the block-receiving cavity, the block extending axially between first and second block ends and having a longitudinal profile generally matching the longitudinal profile of the block-receiving cavity,
• the block also having a wire-receiving aperture extending axially between the first and second block ends,
• the first block end being arranged generally adjacent the aperture of the first enclosure end;
• the second block end having two or more power cable-receiving apertures;
• two or more power cables extending into the second enclosure end, each of the two or more power cables extending into power cable-receiving apertures within the block each of the two or more power cable-receiving opening form a socket for receiving a pipe-spigot of a corresponding power cable.

A welding gun component comprising:

• a flexible hose comprising two opposed ends, said hose comprising at least three internal channels, at least one of said channels communicating a welding wire and at least two of said channels communicating power originating from a single power source;
• a first and second enclosure end at said ends of said hose, each of said enclosures removably attached to said ends;
• each of said enclosures having hollow non-circular cavities disposed therein;
• each of said non-circular cavities having a removable block positioned therein, an exterior profile of said removable block essentially conforming to said interior profile of said cavity;
• said enclosure adjacent a wire feeding end of said flexible hose comprising at least one longitudinally and axially extending channel for ingress of a welding wire, said channel further in communication with a shielding gas channel at an interior location of said enclosure;
• said enclosure adjacent a wire exiting end of said flexible hose comprising at least one longitudinally and axially extending channel for egress of said welding wire and said shielding gas;
• each of said pair of enclosures having at least three sockets for receipt of a mating spigot from said flexible hose, one mating spigot and socket combination for said welding wire and shielding gas combination;
• and at least two other mating spigot and socket combinations for a pair of power cables;
• and
• a means for tightening said mating spigot and socket combinations 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 there through, said conduit further accommodating a shielding gas;
• the second enclosure end including an 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 with an outer profile generally shaped to closely match the non-circular profile of the second block-receiving cavity.
