Trying to teach myself TIG on Aluminium and seem to be getting some sort of contamination no matter what I do.
I'm welding on 6082T6 with 4043 filler wire, coupon hs been cleaned with a dedicated stainless steel brush in one direction and then brake clean and then alcahol (i don't have any acetone yet), i've tried just using brake clean and and ive tried just alcohol to see if either of them were the problem but no.
I've tried switching out from a standard No 6 cup to a No 6 gas lens and tried numerous different flow rates with no difference, experimented with torch angle and distance a lot and seem to get the same result. I'm using 2% Lanthanated tungstens in 1.6 and 2.4mm sizes on an R-Tech TIG 260 tried both the AC easy setup mode and manual mode. Kind of running out of ideas and feeling a little defeated, i wasn't expecting to learn to TIG in a day but this seems like a problem i need to solve before i can even start any practice.
Any ideas welcome.
