Mig gun ends

[elvis]

Are all miller mig gun ends the same? Found a tweco 220 gun for cheap on craigslist and thinking about getting it. I need to replace the gun on my mm251. Guy said it fits his 211 and 212. I would assume it would fit the 251 too?

Check out this 2010 thread. Looks like the answer is a slightly qualified "yes"--but there are apparently exceptions. I do know guns interchange between my new mm211 and very old mm200-I've done it. There are guys here who are far more knowledgeable than I am but this link at least gives you some info.
