I've been playing in the 80 amp range for 16 gauge with 15 CFH and a 3/32 2% lanthanated tungsten.
I've been reading at http://www.metalmeet.com/forum/showthread.php?t=6292 a "no hammer method" of welding sheet metal that I'm going to try, but wanted to hear what others are doing.
Thoughts?

Good Question! Getting too old to remember settings...I will have to get back with you on that one! LOL I use 1/16 or .040 depending on what sheet metal I am welding. 3/32 maybe on 16 gauge or more. I have also found how I grind the tungsten makes a HUGE difference.
If a critical area I use heat sink to keep the heat where I am welding and it works well.
Not mild steel but this is a tank Ijust built for my old pickup
