Looks like the amp is too high and the torch traveling too slow.
First what kind of welder are you using, set up? Getting use to your machine sometime takes time.
I just finished up flanges to 16ga mild steel pipe and my setup was 90-100amp, 3/3" red 2% thoriated tungsten with pulse set at 1 per 1 sec. Usually use filler on the every other pulse. The pulse really puts the weld in good rythem, if you have it I would use it.
On sheet metal work in 20-22 gauges, I'm stepping down the tungsten size to 1/16" and low amp in the 30-40amp. The arc are alot stable with smaller tungsten in lower amp. I do increase the pulse to 10 per sec also.
My machine is Miller syncrowave 200.
