I have a Stahlwerk AC/DC 200 ST IGBT, Basic welder.
Argon 8 l/m
Cup 7
Electrode 2.4mm Tungsten 2% Ciriated (grey)
I have tried currents between 35A and 100A
I have tried the standard 70 / 30 balance and also turning the control to -5 & +5.
Aluminium 2mm sheet.
Attempted Lap joint and flat bead
Cannot get a stable arc or a typical weld puddle even at very small gap between electrode and metal. Lots of pitting and spitting. I cannot form a puddle or a bead.
