Bob,
Again, forgive me if I foist my opinion on you. But my conscience is clear because I've already stated my prejudice against low end machines.
And to be perfectly honest, I'm also prejudiced against MIG machines. Permit me to tell you about my own welding saga.
About 7 - 8 years ago, while working on a VW baja project, I needed to weld up an engine cage. Nobody would do it because it was not a big job. Finally, one of my town's biggest shops agreed to do it. They charged me $50 for about 3 inches of bead.
I resolved to buy some gear and learn how to weld. Luckily, because I make a comfortable living, within reason, price was no object. So I bought a Victor Journeyman torch outfit and bottles.
Next I bought a Millermatic 250X MIG welder. It was the biggest MIG welder that would operate on single phase. If there had been a bigger badder single phase 220V machine offered, I'd have bought IT.
Later, I bought a bunch of equipment from a guy, which included a "round top" Lincoln like I recommended you look at. Then I bought a Miller Maxstar 140 combination TIG/stick inverter welder.
If I could only pick one machine it would be the "round top" Lincoln. If two, it and the Maxstar. I actually use the Maxstar more, but inverter machines are not likely to last a lifetime or two.
I almost NEVER use the Millermatic 250X even though I have redundant gas bottles, and even a high end spool gun.
If you start learning to weld, the only reason you're likely to stop is if it's because you're disgusted with poor results. When I started, I did not envision ever needing to weld 1/2" steel. Now I do it with fair frequency.
What I'm suggesting is, you'll be wasting your money on a machine you'll soon outgrow. Welding with 110 volts is an exercise in futility. At least duly consider:
a) finding a deal on a "round top" or some other vintage machine with some guts and grunt. This will require a heavy duty "dryer" type plug. But you can build a heavy extension cord and plug it into your electric range outlet or perhaps, the water heater plug. Get some ear plugs so you can tune our your wife chewing on your ass...
b) keep saving and buy a Miller Maxstar. A model 140 (if they still make 'em) will cost about $700 new.
I've got two Syncrowave 500 machines, that, when new, retailed for well over $8,000. I never use them either. I almost always use the round top Lincoln if my project is close to it, or the Maxstar if the welding work is farther away.
The Maxstar pretty well tops out at a 1/8" electrode. The round top Lincoln will melt 5/32" electrodes all day long.
I'm sure lots of MIG lovers will come outta the woodwork. But I insist stridently, that for the hobbyist welder, a stick machine (or stick/TIG combination such as the Maxstar) and a torch are, if not all you need, they will get you miles and miles down the road to a fascinating, versatile, and valuable do-it-yourself adventure world. And you won't be kicking yourself for having bought a toy.
No offense intended to those who have and use the machines you're considering.
Regards, Vernon
