I've been trying out fillet welds with some 5mm aluminium, the arc seems to wander between the two pieces and heat up the metal very quickly using a No.5 cup & a 2.4mm tungsten about 5mm past the end of the cup. I've tried upping the frequency to 120Hz and backing off the current to 135A, which was a little to low, 145A was workable initially - should I increase or decrease the Argon flow of 5l/m?
here's the best one....
