I have 175 MM Miller that's 5 or 6 yrs old on it's 5th( I think) 10 lb roll of solid wire. So far it doesn't owe me a dime!! I've removed the liner 3 times to clean it and removed the cabinet a couple of times to blow the dust out. So far I'm very pleased with it. I've built many different projects out of 1 1/2" x .060" salvaged square tube. I have welded non-critical 3/8" beveled and preheated w/ it cranked all the way up. I bought it new and my grandson is the only other person to use it besides me.

They are good machines but it is an older unit so what Price are you paying for it?

 

Why not take a look at the MM211? It runs on the same 220V as the 175, but has more than 30 Amps more output than the 175 for a little more money. You can also run it off 120 if you need to use it where 220 is not available. It is the same size unit as the 175 also, just a little heavier, but I'm sure your going to build a cart for either one like most everyone else does that has one. Being a higher output machine it will probably be several years longer before you decide to upgrade, if at all. It's better to get more machine than you think you need now, than to upgrade to more machine later. A lot of the guys on here that have MM211 seem to be very happy with it, and I plan on getting one if I can find someone that wants to buy my MM140. It's a good little machine itself, but I would like the extra output when I need it without having to fire up the Bobcat for higher amperage/thicker material.

 

http://www.weldersupply.com/products.asp?id=36&cat=Welding+Machines|Mig+Welding try here for great price. It's not shown where you are located. The welding supplier is in wisconsin and i have bought from them but pick up only. Go with the 211, best buck for the money, good luck

 

go with the mm211. for the the money its the best welder out there.
after all these years the 211 with a spoolgun has been out, its
hard to beleave lincoln cant even make a welder that comes close to it

 

hey Ed, how many years has the 211 been out? just curious what constitutes all these years.

 

it would appear by the op's post he is looking for a used machine since the 175 hasn't been built in several years. so how is he going to save money by getting a new 211? i have seen 175's as low as $500 bucks with bottle on cl. good luck coming close to that on a 211. my 175 is about 6yrs old. i bought it new and never a problem and going strong and i wouldn't part with it for $800.

 

the 211 has been out for 2-3 years I think, and lincoln actually just came out with a comparable welder to it.
