T6 turbo dart

Thanks, I will give that a try. I was trying to mess with the ac balance to reduce the cleaning zone but it wasn’t helping.
I’m using a Chinese AHP alphatig 200 off Amazon. Using a #8 gas lens on stainless and a #5 standard collet body on aluminum.
Very nice! I have a Miller Syncrowave 250 and REALLY want an inverter machine.
They weld aluminum much better.
How do you like the Alpha? I have not gotten to use one yet.

for sure the biggest thing is preheat to get the shiny weld and less arc erosion.
You are making some beautiful welds. Looking forward to seeing this all done
