MIG Gun Conduit Stuck

[FlashBlind]

OK, I've been a viewer of this forum for several months now, and have have had all of my questions answered by just searching various topics until now, so it's time to get off my neck and register..
I have a MAC Tools MW 250 MIG Welder (Miller Vintage 250 with Tweco Gun) and while attempting to replace the conduit yesterday, found that it had corroded and is stuck in the Miller connecter plug (Welder end of the gun/hose assembly). Both conduit end caps with set screws are off. I tried to use a small punch to break it free, but no luck. I added a little PB Blaster penetrant before quitting last night. I looked at the Tweco web page diagrams and will attempt to remove the connector plug with conduit from the rear power connector to isolate the problem and possibly twist the conduit free/ out with a pair of vice grips. Trying not to break anything..
Thanks in advance for any help or advice.

stuck conduit

You might try some Liquid Wrench. Seems to loosen almost anything.

When you get access to one end of conduit if you still have need to turn conduit chuck it into vairable speed reversable drill. Then you can turn it
correct way easily.

Have fun.

It sounds like you may have missed a set screw...also the liner comes out from the welder end of the cable. The drill idea is a novel idea, but if the drill turns the wrong way, you will be adding problems, and may end up buying a whole new assembly.

Thanks for all the replies.
Well, after I went back out and disassembled my gun, I found out that the brass endpiece is attached to the conduit, and of course it came out easily when pulled from the correct end. Lesson learned- look at the instructions in the package with the new conduit.. Anyway, I replaced the conduit, trimmed it to length and cleaned/ adjusted everything. The wire feeds smoothly with much less roller pressure. I spent an hour or so practicing on various scrap I got from my local Welding Supply. Spray transfer is getting easier on the thick stuff (3/8"- 1/2"), so smooth and quiet. Still difficult on the thinner steel. I'm a happy novice.

Now that you know how, clean it a bit more often.

I've been working in Emergency Medicine since I was a teenager. Just retired from the Army last fall, with the last 10 of 21 years spent as a Physician Assistant. I have a small ranch and besides the obvious of repair and upkeep of the place, I've always wanted my own welder, rather than renting/ borrowing. I found a deal too good to pass up on a Miller Vintage 250 and the guy threw in a Lincoln buzz box in for free! I'm getting the hang of MIG, and will start a long list of projects this spring. Life is good..
