I am going to learn with regualr wire and gas as that is what all my buddies run and they will be teaching me. I cant ask them about this welder as they want me to get a 240v big beast and buy it one time instead of my buying this and having to upgrade again. They dont beleive in 120v. But here is the kicker, I will only be doing basic stuff I have zero interest in being an expert welder and taking on work on big thick steel jobs. Basically rust repair panels, mower decks, and pickup bed supports. Occasionaly a plow if I break it.
All I can say is don't be naive, it's truly nice to have more capability. With welders and tractors, everyone always wishes they'd purchased one step bigger.
Now, you can regard that as the masses talking down to you, or the voice of experience. Your choice.
The Miller 211 multi-voltage is a sweet machine, esp at ~40 lbs with inverter tech. My Hobart 210MVP which is still transformer is more like 90 lbs -- borderline impractical for mobile use. My already-once microdisectomy'd back is no fan of loading the 210MVP into a truck.
I will grant you the M211 is quite spendy at Great Reset pricing, but still an investment for life.
DO NOT be afraid of flux core. It burns hotter and digs deeper. If you really think you're gonna repair plows with 110V, please consider using flux.
Finally, if you've made it this far, it's not just about capability. Like most things in life from vehicles to power tools, more power means a better user experience. A 240V machine lays a better, smoother bead while allowing greater travel speed, and even that isn't an accurate description.
It's the difference between pulling 10k lbs with a 1/2 ton, vinyl floored V6 vs a fully loaded 1 ton diesel. You don't have to use the extra power, but when you need it you didn't even realize any additional effort was expended.
Hobart makes solid machines with great tech and warranty support, so if you want the H140 it's a good choice. I still don't trust Harbor Freight machines no matter how great the reviews.
