I'd put the gap down to as close as you can get without out touching the puddle. 1/8" is too much. Flow is too high if you are using our regulators. Our regulators are in lpm, not cfh. Turn down to 7. Use a #5 or smaller cup.

I'd also try 3/32 electrode at about 50 amps and see how that works. the 3/32 should handle that, and the arc may be a little more fat.
