It certainly does appear to be made by Miller. It would sell for about a grand here. Make sure it welds first.

 

I would say a Grand in good shape. (PNW) Miller has confirmed it's a Vintage 250.. Makes it a somewhat upgraded MM-200

 

Bought it! It's like new and he got a grand out of me, I pulled the lids and it is copper wound transformer, blew it out and it welds 0.35 just fine. Caps looked really good to. Ill get some pic's up in a few.

 

I bought one new in 2001 off the Mac truck mine has been an outstanding machine other than the short cheap mig gun it came with, I upgraded to a 20 foot miller gun.

 

Mig gun is crap.. What are the chances you have the part number for the 20 foot mig gun?

 

Any gun with a miller back end will work on it.

Take a look on eBay

 

Thought so, I pull the gun off my old miller feeder head and it fit fine. My local suppler was wanting serial,model # and so on.. I have a 20' Radnor Pro coming for it.. Then all my consumables, tips, cones will interchange from my other machines..
Thanks for the info and help!

 

Keep the 20' gun straight and change liners often or you will have feeding problems.
You may find the 15' gun is a better fit with less problems.
