So I was wondering. Can I buy a tig torch and use my argon bottle off my mig welder hhok it up DCEN to my Lincoln and TIG steel? Someone told me the other day you cannot tig with a SA200 like this. Just not sure whay you could not simply adjust your current at the SA200 and scratch or touch start. Have your gas control on the tig torch . You would not have a pedal to adjust current, nor pre / post gas like some machines have.... Just wondering. I currently am taking a TIG class and we do not hace foot pedals we adjust at the box and touch start so what would be the difference?
