Hello, I'm new here, first post. I just ordered a Powertig 200DX. Should be here in a week. I'll pick up an argon tank tomorrow. I have not tig welded for 30 years, I went to a Votech for welding but never finished. I was just getting into tig when I dropped out for stupid punk kid reasons. and back the then they were huge heliarc machines. Im looking forward to my new machine and start fusing again.
