I have a Lincoln Wirematic 250 Mig Welder I purchased slightly used. The argon gas runs continuously out of nozzle if on at the bottle. Gun and lead are new. Any ideas.
Reply:the gas SELINOID is either broke or energized find it and check current. it is most likely not the triger cause the wire is not running also but a wire may be crossed close to the selinoid its self or it is stuck open
