I just ordered a new TIG welder on Ebay- - - -one that's supposed to be able to weld aluminum in addition to steel and stainless. I already have the Argon and CO2 tanks and regulators that work with my MIG setup. I really like TIG- - -I used it a lot while I was a welder and pipefitter at E&J Gallo winery in Livingston California. We ran MILES of 4" thin wall stainless tubing there, to pump the grape juice, apple and pear juice, and finished wine products over more than 100 acres of storage tanks.
