I'll probably try and get myself a tank this weekend for my new 140st. What's the best combo of tungsten and wire to start with?

I've TIG welded in class (for 3-1/2 whole hours!) with 3/32" or 1/8" 2% ceriated electrodes and 3/32" wire (I think). Welders were big Miller multi-process units. I think the amps were around 95.

Is that combo too much for the little 140st? Should I start with say, 1/16" tungsten and .35 wire, or something like that?

I'm practicing on 1/8" scrap, BTW. In class was 3/16" and 1/4". All mild steel.

thanks guys
