Millermatic 200 restoration, Help and advice needed Please!

admin

Hello Welders and Millerphiles!I have always wanted a Miller, but budget restricted me.But last week I snagged a Millermatic 200...Its in rough shape, but I am hoping I can bring it back functionally and cosmetically!I need it to do some heavier stuff that my 110v Snapon Musclemig 140 can't!Its a 1988 by the serial number #JJ493201 stock number is 048291So, first issue is a missing the Wire feed motor.... the gears are there, motor is gone.According to the manual, its Part #31 on page 65.#113 688 :  1/2hp 115v DC 3560 rpm.I found a mention of it being NLA and my searches have turned up nothing.Anyone know better or know if there is a different part that can replace it?Thanks in advance!

Reply:Yes, Thanks!I found some of teh stuff I might need there for good prices, but not the Wire feed motor..
Reply:113 688 is obsolete from Miller. The motor is a 90 to 100vdc motor. Motors in newer welders are all 24vdc. so using a newer motor and drive will also need a new motor control pcb.
Reply:Yes, seems to be. I’m tracking down a used motor, but if that fails...Can or has that conversion been done successfully?Which drive motor was used and which PCV?Thanks!
Reply:I may have a used one I can check if you are interested. Let me know.I Fix Stuffwww.millerserviceparts.comwww.lincolnwelderrepairparts.com
Reply:Thanks for the input!Yes, Diode, shoot me a PM if you have one.Has anyone converted this era Millermatic to the later motor?Is it just the Feed motor or is it the whole wire feed assembly?What PCB would I need?Is it a simple swap?
Reply:Could this be the equivalent?Gearbox looks similar shape..Miller told me  115VDC 1/20hp, 40:1 ratio and it was about $900 in 2006...https://www.grainger.com/product/DAY...or-90VDC-6Z415I cant justify $900 obviously...
Reply:I looked I do not have a motor. Closest thing I have is a used 90VDC motor from a s-52 Wirefeeder.I Fix Stuffwww.millerserviceparts.comwww.lincolnwelderrepairparts.com

Reply:This would be a really good motor, just that the bolt pattern is about approx. 1 inch wider and the motor housing a couple inches longer than the MM200 and the aluminum wire feed assembly is different also.

Reply:Great info!The info I have is my serial number welder had a 2 wire motor... Miller confirmed this on the phone and said "115VDC, 1/20th hp, 3560rpm, with 40:1 reduction gearbox".... so 90rpm ishLarry Burros said he had a 2 wire and a 5 wire motor, but when I emailed him for a price, I didn't hear back... So I called him... and he was super helpful, and obviously knew his stuff, but he said he would let me know....

Which seemed to mean sometime in the future... LOLSo, if my motor originally ran on 115VDC, can I use a 90VDC motor?If not, then is the a PCB I can put in my welder that outputs 24dc so I can find a more modern wire feed system???

Reply:I really do appreciate the input!I cannot seem to post pics here, but I started a thread over on GJ, and there are pics of the gearbox and what I have left there...I was kind of assuming I was missing the input gear that would have been attached to the motor shaft...https://www.garagejournal.com/forum/...d.php?t=477385Funny you should mention the Snap-on MM.... thats my current Mig Welder, but only the 110v 140a... it a great welder but I want something with more Omph for heavier stuff.I have the Scratch TIG, and spoolgun for it too...I looked at buying a Spoolgun for this unit, but the prices looked prohibitive, so wanted to exhaust my search for other solutions first... same goes for a wire feeder..
Reply:Good luck looking for a motor for that. Every time I see a Miller MM200 on craigs list they want over $2000 for them, and they look beat to death. They always seem to disappear in a few days. Haven't seen any for parts either. My recommendation would be to wait for a Snap-on MM250, or  a Snap-On YA-212 both are pretty similar to the MM200 Plus the spool gun, and tig torch, and many of the feeder parts are interchangeable. I've owned a YA-212 for several years and it came with a lot of consumeables, and it has run really well on steel, stainless steel, and aluminum. They usually pop up on craigs list and sit for months at $2000 and after a while they drop to about $1000 or less before they disappear. They were usually over priced when sold to an auto shop by snap on dealer,  original owners want to get their money back. Generally good machines 12 tap transformer 14-30v 230amp rated machine. Most look beat to death just like the Miller, overspray tinted with paint gun drips, tons of dust inside. Systematics is still selling all the parts for these right now. Just my thoughts on it, hope you find something.Airco 250 ac/dc Heliwelder Square waveMiller Synchrowave 180 sdMiller Econo Twin HFLincoln 210 MPDayton 225 ac/dcVictor torchesSnap-On YA-212Lotos Cut60D
Reply:Thanks for the input!Actually, that makes a lot of sense for me to do that...I absolutely LOVE my MM140, but being a 110v, it lacks that 3/8" ability I need.Still want to get this one fixed up... guess I could push it in the corner for now... its probably used to that feeling.. LOL.

Reply:Still gonna restore it...But.... I picked up a Snap-On MM250SL today... really clean, looks barely used... original gun and ground clamp, and a full spool of .30... $900.
Reply:good deal !  Hopefully you got some consumeables with it. USAweld.com has parts, and  HTP replacement guns and parts. If you do bodywork use .025 wire in the MM140 . and .030-.035 in the MM250 for thicker stuff, and for the spool gun. Here are some 1/2" fillets on the YA-212A .

Reply:Looks great to me!I was planning to sell the MM140SL and just run with the 250 but am unsure how it will be on the thinner steel I need to doI posted that question in the other welders thread so as not to sully this one.
Reply:I think the MM250 will do fine on the sheet metal. My YA-212 will do 16 gauge and 18 gauge mild and stainless steel very well. That was with 035 wire, I was on Tap 3 or 4 so I wasn 't on the lowest setting. Haven't tried .025 wire in it yet, I don't have the feed wheel for it . You should give yours a try with .025 wire in it, I think youll be happy with the result. Do either of them have spot and stitch timers ?best of luckAirco 250 ac/dc Heliwelder Square waveMiller Synchrowave 180 sdMiller Econo Twin HFLincoln 210 MPDayton 225 ac/dcVictor torchesSnap-On YA-212Lotos Cut60D
Reply:Good!Hope to try some welding with it in the coming week.Yes, both the 140 and the 250 have the spot and stitch panel... I think its standard with the MM's.
