Well I think it is about time I stepped up my game and purchase a TIg Welder. I am going to buy an Old School tried and tested Machine, an L-TEC (made in USA) 250HF Squarewave AC/DC TIG welder, 250 amp. It does Stick also AC or DC. The price is right at $700.00 and comes with everything but a Bottle. I have an extra bottle that will work. This machine will weld up to 3/4" thick material. Any ways the guy that sells the welder does classes also. I use to do some serious Gas/Acetylene welding back in the day and I was actually very good at it. I told the teacher of the class that I use to do Gas welding and he said I should pick it up quick. He said he will put me on a Mig first to see if I have puddle control, well I know I will pass that test. Then it is off to the Tig. He is going to teach me how to set up properly to TIG weld Aluminum, Steel, Stainless Steel, and ChromeMoly (4130). I am excited to learn something new.
