I have a profax mig gun,does the liner have to be profax or willany work as long as diameter and length is the same?
Reply:It would be better to have the Profax one. Some of the Miller and Tweco's are compatible with the Profax ones. Their catalog should tell you what will work. My LWS has an old one he uses to get the right ones. He still can't seem to get a new catatlog for some reason.
