TIG is more finesse. If you have too much heat - back off the throttle.... CONTROL.
How well can you see? Can you see the part lines? Can you see the puddle develop? Can you see it freeze when you add fil?

I think one issue I was having was the grind on the tungsten with my high-dollar grider was too coarse, I've since modified the grinder wheel with 180 grit sanding disk on the side and that puts a nice finish on the tungsten.
A little funny - I switched to AC to practice on aluminum then switched the AC off and started running bead on 16 gauge to get a feel for the differences in metal..........I don't think the machine switches back without powering down........either way I proceded to securely weld 1" of that 16 guage to my 1/4" work top.
