And it's easier and less expensive than you'd think. Get on youtube,
I wouldn't touch a TIG with a ten foot pole.

I've built several aircraft with oxy-acetylene and like sound, properly soft welds, thank you. Plus, O/A alloy is easier to work. TIG creates too much of a HAZ for my taste. It's possible to get roughly ok welds with TIG, but you need an o/a torch to normalize afterwards, so what's the point? TIG is an answer to a question not asked, imo.

The MIG is for learning and building fixtures. I might try it on the 3" pieces, but the rest of it will be O/A.
