Ray,
For all my non water tight welds I used a 250 amp miller MIG welder I paid
around $1500 for about fifteen years ago.
For all my more critical welds, I used a Lincoln "torpedo style" welder.
It's a very old motor generator set type of welder that sounds like a jet
engine when it's spooling up and running but supplies perfect DC current. I
paid $25 for it about twenty years ago. It's probably fifty years old.
Since better rectifiers are now available they're not used much now because
of the maintenance they required and the noise.
Like most of the other advice you already got on the subject, it's not as
much the machine or what you pay for it. Just so it's large enough to
handle the material thickness. It's like that old joke of asking directions
to get to Carnegie hall............. Practice Practice Practice
