Hi chaps, I’ve been a bit of a lurker for a few years. I finally bought the Stalwerk to tig up a stainless exhaust (pretty happy with the job) and decided to have a play with the AC. Now here’s the fun bit, there is nothing in the manual about settings, I can sort of get it to start an arc but it will only create a stable arc in the first 1/8th of turn of the balance knob. I realised (I think) that pedal is best but could anyone give me some pointers? Ta.
