Go check out welding tips & tricks.com, Miller/Lincoln/ect. dah skills are in dah hands as my old welding instructor youstah say
I'm a fairly good Mig guy and have a Miller, they just had a good deal and 6mo interest free financing @ the time so I went with them.
If I need TIG I have a great resource and they use Miller, good luck and let us know how you make out.
