I got a Lincoln Squarewave 175, the early model that goes down to 12A,
second-hand for $1200 about 10 years ago. At that time $1200 was a
typical "street" price for them. I bought it from a welding dealer, it
wasn't hot.

I've used better ones but it's OK for the little I do. I took it to
welding class to practice with and compare to theirs. I was about
equally bad, and the instructor equally good, on aluminum with mine
and with the big one the school owned.

I spent 8 weeks running practice beads on aluminum. Some came out fine
but I never did learn to weld a consistently good bead without a few
practice runs.
