Bought a mystery welder. Mac Tools stickers on both sides. Front panel says MW 275N. No info on the web that I can find, but the search does bring up the Mac Tools website. I emailed them and waiting for replies.Can someone please identify it?I read in other Mac posts that it could be a Miller, but I can't find any matching Miller machine out there.Photo album - welder and the first repairs (AC cord):https://photos.app.goo.gl/dL7QTjFDvzrb1yhZ6***First machine, bought on a whim to learn how they are made and how to weld.The honest seller said "sure it works, but I don't have 240V here to show you" ...so I knew this was an inop, but for the price ($250) I decided to get it for learning and possible repair.Didn't take long to discover why the machine was parked. The AC cord pulled out (looked like some damaged outer insulation at first) and the ground lead was pulled off the chassis. This was the main ground lead.I don't know whether this welder will power up without a proper ground. The ground spade connection point had surface rust on it. Maybe the machine kept going or maybe just sitting and rusting. There are two buss fuse holders. One has a good fuse. The other had tinfoil around it. No obviously meled insulation inside, but who knows...I fixed the AC cord but have not plugged it in yet. Better stop here. Looking forward to your comments.--Mike

Reply:I've looked those 250 and 270 manuals over, thanks whtbaron!, but the diagrams don't match up. For one thing, this machine has the intriguing "Spot Time" knob and the others don't. Can it do spot welding?I think what jpump5 said may be the right direction. When I searched for the EN60974-1 number off the front panel, I saw a bunch of references to some EU standards (and various manufactures like Lincoln, etc. stating compliance). One component - the large heat sink? looking thing - does have a 2007 date sticker.Mac MW 275N >> MN260D
Reply:I have no clue... yours is the first one I've seen. I did find this in another thread though... "Mac tools welders and plasma cutter are often made by CEMONT an Italian company which is now part of the Air liquide Group.They make Oerlikon and SAF-FRO. It's very good kit if that's the case. I have a mac plasma cutter.""Who Makes MAC Welders? Find out HereMAC has been a famous welder in Europe, but only one manufacturing company is affiliated with it and produces the welders. However, the company is CEMONT, located in Italy; its a part of the Air Liquid Group.They provide many other things as SAF-FRO, Oerlikon; the welder and plasma cutter package has a positive review among everyone. Once there was a rumour like the Hobarts is producing MAC tools.As a result, a question arose, MAC tools= Hobarts? Now, the answer may be clear to you that Hobarts was never involved with MAC tools. The brand, along with Century and Dayton, used to manufacture the MATCO welders."Last edited by whtbaron; 2 Days Ago at 12:27 AM.The harder you fall, the higher you bounce...250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes
Reply:Many thanks for that! I made my way through the Cemont web pages and fired off a question to them.I'll update this thread with any info I receive.Mac MW 275N >> MN260D
Reply:Looks like I found my answer (almost). A closer look at the current Mac Tools MW260D shows that my machine is the earlier version, with the main difference being the addition of an electronic panel on the 260D in place of analog controls for the same functions on the MW275N.https://www.mactools.com/products/mw260dSo that's the machine I am hoping to learn my welding on. Wish me luck, I know this is a far bigger machine than any beginner needs.I have to update my 240V garage wiring, get a helmet and some gear and get going...MikePS of all the companies I emailed about my welder, only Miller replied on day one. Have yet to hear back from all the rest, including the mother ship.

Reply:All I can say is that I found more info and photos of the MW260D in the wild than on the official web page. Maybe just supply chain issues.Mac MW 275N >> MN260D
Reply:Placed a call to MAC Tools tech support and got the answer: this MW275N machine was made between 2006 and 2009, in the US, by a company in NC - Nu Tec Systems. Later in the day, both MAC and Nu Tec responded with an Operators Manual, wich included a wiring diagram and some parts rosters.Nu Tec is also the confirmed manufacturer of the current MAC/Matco MW260dIf anyone needs a copy of the MW275N manual, I send you a PDF.--MikeMac MW 275N >> MN260D
