I just finished posting about how much I love my miller 211 inverter and how it compares to my brother's miller 220 and miller 252. The OP was considering the hobart 210mvp which is the cheap version of the miller 211.
I forgot about the fan on demand feature, but I love it. It is so great that I wired my Miller 330abp 460 amp tig with relays, contactors, and a timer so the fan and pump are on a timer and it switches off my swamp cooler when I press the pedal to start the fan and pump. It times out and shuts of the fan and pump and turns the swamp cooler back on.
I bought my 211 in 2015 also and it had a nicer arc than the 252's transformer, both using the same roll of LA-75 wire for corten steel on the same parts. The arc from the 220 is very loud when mig welding. My brother and I both noticed it vs. my machine or the 252. To have portable ac tig and the ability to change the waveform would be great and the screen with actual speed and voltage is great, but I like how light the 211 is. The auto set is perfect and I don't care about memorizing settings and like just moving the knob......often times to a hotter setting for steel mig so I can run faster. Autoset works great for aluminum and stainless as well and fluxcore. I kept the roll of 0.024" wire from my miller 135 but never use it. 0.030" is fine down to 20ga and most of my work is 18ga or heavier. 3/8" steel is no sweat for short runs.
The 211 inverter and spoolgun is one of my favorite purchases out of many tools I own. The 15' gun is a must and a 25' 4ga work cable matches the spoolgun. It was certainly worth paying for the nicest machine and I have used all of the features and potential of it. There is no way I would buy a hobart instead of the miller, even at current prices. I do too much welding and too much variety of materials, projects, and locations to not have this machine. My brother owned a 252 but bought the 220 after using my 211 on job sites. It depends on what you like and need.
My other post with more about the same topic:
Is anyone running a 210mvp with a spoolgun on aluminum? I have enough projects that maybe it time to skip the syncroweld and get a mig. I wouldn't mind a bigger mig but I have had several small jobs (steel) that I could have done if I had a 110v machine and the 210 can do both. A 250 amp...
