An air cooled welding gun assembly adapted to be operatively connected to an electrical power, shielding gas, and weld wire feed mechanism through a cable assembly and a connector assembly. The welding gun assembly includes a front connector block having a plurality of open recesses or channels wherethrough pressurized air is conveyed, and the connector assembly includes a rear connector block. Power, gas and cooling air are contained within the cable assembly and intercommunicate the connector block of the welding gun assembly with the rear connector block of the connector assembly. The welding gun assembly also includes an air cooled nozzle assembly. In one embodiment of the air cooled welding gun assembly, a hand held air cooled welding gun assembly is provided. In another embodiment, a robotic air cooled welding gun assembly is provided. In both embodiments, pressurized and refrigerated air cools non-insulated conductor wires along with cooling a rear connector assembly, a cable assembly, a front connector assembly or handle assembly, a conductor tube assembly, and a nozzle assembly.
