I built my 1 ton TJ with a HH140.
That said, if I were in a position to buy again, I'd go straight for a 210. Main reason I went for a 110v machine was I lived at home and it would have cost a bunch to rewire the garage that I'd be moving out of in a few years since the fuse panel was full and my dad wasn't too happy about me even wanting to have that done.
LOTS of prep, preheat with a propane torch, and multiple passes on all the important/thick stuff.
