ABSTRACT:
A gas seal for a MIG gun system for preventing the leakage of shielding gas out the rear end thereof which includes a connector assembly, which seal is embodied in an elongated tubular member which has an outside diameter sized to be positioned extending into a bore extending through the connector assembly of the MIG gun welding system. The tubular member has flange means on one end including an outwardly extending annular flange which has a surface adapted when installed to be in surface-to-surface contact with the connector assembly adjacent the bore therethrough to form a seal therebetween, and an inwardly extending flange defining an opening of a size to permit welding wire to move therethrough. The inwardly extending flange and the adjacent portion of the tubular member form a cavity on the upstream side of the inwardly extending flange. A resilient member is positioned in the cavity upstream of the opening defined by the inwardly extending flange. The resilient member has an opening therethrough in position to register with the opening defined by the inwardly extending flange, which opening is sized to resiliently engage the welding wire when the welding wire is positioned extending therethrough. The invention also resides in provision to lock the tubular member in position in the adapter bore.
