I was schooled in the adult ed dept of the Mont. co school system it was a gas class, then a stick class, I asked the instructors for a TIG class and they said to sign up for the next gas class and they would work with me on the TIG machine, It was great stuff almost one to one ratio!,, I later bought a Miller Synrowave 250, and a Millermatic 150 mig,, very happy with both machines along with Youtube and this guy you can learn a great deal http://www.weldingtipsandtricks.com/index.html
