Reviews & Ratings

Rated 5 out of 5 by from I love my 252 This machine is made in USA! That is important to me. It welds great from light short circuit to heavy spray. This is my big iron that I roll out when I have to deposit some metal. I would not hesitate to recommend it to a friend.

Rated 5 out of 5 by from Smooth as a baby's bottom As my old man says "even you can weld ok with that machine''. This Mig welder will make just about anybody look like they actually know what they're doing. So versatile, reliable, and smooth! Should be in every shop!

Rated 5 out of 5 by from This product I had been wanting a welder for 3 years, but my husband and I couldn't agree on what model to get. He wanted a 211 and I wanted a 252. Last Christmas he surprised me with a 252. I absolutely love it. I build horse shoe projects, and this welder is so easy to regulate, I can weld 3/16th shoes, and change settings and then weld a new floor in the throat of his combine, which was much thinner than horseshoes.

Rated 5 out of 5 by from Excellent Machine, Does it all !! I've owned my 252 for almost a year. I'm building a 69 Camaro and using a 2013 ZL1 Camaro floor pan and drive train. The 2013 floor pan is aluminized which is almost as bad as galvanized but the Miller burns right thru it and blends both metals together well. I LOVE the feature to be able to just grab the spool gun and start welding aluminum and not doing any switching to the welder. The Spot / Stitch weld timer works great allowing you to dial in the exact time for lenght of weld time and burn back time. I would recommend this welder to Everyone looking to weld steel, stainless steel, and aluminum.

Rated 4 out of 5 by from Best Welder I've used, second only to the Millermatic 251 This welder is everything I could ask for. I have taught my entire family to weld with it including my 57 year old mother. All of them can now make professional welds, mostly because this welder is so easy to use. The only complaints I have is I miss the non-digital"ness" of the 251 and I don't like the plastic wheels on the cart I bought with it, both seem like they will eventually break. In all fairness nothing has broke and I have had to do zero maintenance and I'm very happy with the functionality so I do have to say it's the best mig machine setup I've ever used.

Rated 5 out of 5 by from my 252 handles everything I throw at it. I bought my 252 when I had a sand blasting business and it was perfect for anything I needed welded. I am a novice welder and it helped make me look like I had been welding for years. Just set it and go. Never had a bad weld from it. Several friends that are experienced welders love to stop by and barrow it when they need to make tougher welds. Would not give it up for anything. One of my favorite tools in the shop.

Rated 5 out of 5 by from Perfect for every job in my shop! I am a High School Agriculture Teacher in South Carolina. We had an older Miller MIG welder when I first started teaching here. Upgraded to the Millermatic 252 after the first year. One of the best decisions I made that year. Very easy to teach my students with. Very maneuverable around my shop. Not very bulky. Doesn't take up a lot of space. Does great from small exhaust jobs to fabricating a utility trailer. Would definitely look at buying a second rig in a couple years.

Rated 5 out of 5 by from The welder is so easy to use! I bought the 252 for home/hobby use. Not being the most experienced welder I needed one that is easy to use. The 252 is just that. The instructions for setup and welding were so easy that my welds looked good right away. I love the matching metal thickness to wire size to the correct power and wire speed chart mounted to the machine. Great machine, I highly recommend this product! Mike48
