A weld gun (10) includes internal, external (30) and structural (32) devices that dissipate heat generated at electrode tips (20) without requiring a continuous external source coolant. The internal devices utilize heat pipes within the electrodes to transfer heat to secondary heat removal features (30). A heat capacity on the weld gun contacts external heat sinks to directly conduct heat away from the weld gun after a completed weld cycle. Alternatively, the heat sink, the heat pipe and the secondary heat removal features are combined structurally on the weld gun arm by forming the arm from a plurality of plates (30) separated by an air gap. |
