I used one of those in the tig class I took last year. I found it in the corner of the shop all dusty and forgotten about. No one would use it, everyone wanted the fancy new miller 180's and water cooled 250's. Well, I sat down and got acquainted with that old boy and gave it a good cleaning. I even had to buy my own cup and collar for the torch. It worked GREAT. Frankly, it was easier to weld stainless with the linde than one of the millers. They all made fun of the big clunky pedal. After all that, the dirty dogs wouldn't sell it to me. It's probably back in the corner I found it in. I think you will be pleasantly surprised. It got me an A.
Best regards, Jon
