Welcome to the forum, and congrats on the new machine purchase. I can't imagine having gone that long without TIG welding though! After I learned to TIG in college, I felt like something was missing once I lost access to a TIG machine! That was probably the longest 3 years of my life (haha). One thing's for sure though, that new machine of yours is nothing like the last TIG welder you used...It's MUCH better! A lot has changed in 30 years.
