- A quick look at another project I've decided to undertake. Whilst looking around for a decent used mig welder, I stumbled upon a surplus auction for a non working Millermatic 250 from a voc tech high school, and decided to take a chance.

I just bought one of these ! Cant wait to get it tomorrow and try it..
I paid $1800.00 for mine ready to use. $50 bucks was a freaking steal on that unit. All the hardware it needs to run is still costly, but you got the heart of the unit at a very good price.
Steve I think u got the deal of the century. even if u got to spend a few hundred bucks to fix it. your still ahead.
I have the same welder and it works awesome and had given me years of perfect service
Thanks Dave. I took a look inside tonight. no major components missing or burnt. I am going to wire up power in a day or two.
Well Steve looks like a good purchase.With your electronics ability you should be able to make it run.Hope ebay has a deal on a used gun.Good luck luck my friend.
Thanks Doug. I hope you're right. those guns aint cheap!
My welders came with those Crouse-Hinds plugs. Sold 2 of them on EBay for over $100.
Thanks. I figure worse case scenario I'll sell parts out if it. big question is, is the main pc board okay?
That's 4 mins I'll never get back
Do you still have this 250 ? I'm looking for the spoolgun module.
Hi Steve I don't know if you have heard of the company www.usaweld.com they have that Miller M25 gun in a 15ft for about $160.00, if you can get the rest working cheap.they have all kinds of other goodies for welders to. I got them to ship me a gun for my old Sealey 150 here in Canada, They were real helpful as my welder was for the English market, and we had to do some figuring out what would work. It was well worth it how well my welder works now, the old gun wasn't right for 15 years.
Thanks. I just saw an original Miller m25 in new condition sell on eBay for around $150. But I want to do some more tests before buying a gun, so I passed on that one.
I got a Miller Big 40 and it can weld a ship.
Saprising your only person who talked about fixing a broke one every one else its just giving ponters like for the guy who is staring to weld and bought one few month ago im having problems wher mine welds great then its like it has problem feeding wire like the hub is geting jamed or the even though the nut isent over tight i yes i replaced the hose over the years do all maintnece make shour all feed wheels are alighned its like you sead the wire kept welding to tip because it will be welding feading fine all a suden the rfeeders cant pull the wire like spool hub is to tight even though its not i did notice it started having troble with disty stuff cloging all the hose and tip and such
most call it a whip
Which segment addresses the fix for the burn back issue that plagues this model? Thanks
Dan Phenicie hello. I haven't done a video on this yet, but the well documented burn back issue on this model occurs because this is a "hot start" machine. It has full voltage at the tip on arc start, regardless what the settings are. There is a diode you clip to disable hot start, but Miller suggests installing a switch so it can be turned on again, for larger wire sizes.
THANKS, I found some help . .post #14 www.millerwelds.com/resources/communities/mboard/forum/welding-discussions/7346-mm-250x-pops-back
So how did you come out on the welder? never seen a update video.thanks
Dave Hill hi dave. no update video because i haven't done anything since my last video other than get those missing springs. now i need a co2 tank, and gages. no luck on a cheap tank yet.
wish.com..had some really cheap buy on spool guns..
You could sell the connector with the cable for about $150....
