ABSTRACT:
A method and apparatus for cleaning a metal inert gas arc welder gun of a type having a housing and a flexible conduit disposed in the housing. The flexible conduit has a first end for feeding a consumable welding wire therethrough and a second end adapted to engage with a tubular welding tip for selectively feeding the consumable wire through the flexible conduit and through the welding tip for use. The method involves removing the consumable wire from a major portion of the flexible conduit, injecting a liquid cleaner into the flexible conduit until some of the liquid exits the other end thereof, forcing the liquid cleaner out of theflexible conduit and moving the consumable welding wire back into the flexible conduit and tubular welding tip for use.
