No, I've tested it. When I short pin 1 and 2, there is spark on the output.Maybe the HF board is broken.
Yes, when its in that position it can weld, but without hf ignition. If i short pin 1 and 2 to the hf board, its making hf spark at output.Looking at the picture you have posted the HF switch is in Lift Arc.
Mode select switch? Where?Also mode select is on remote?!
Ok, if i switch to hf there are no modulation or HF spark. If switch is in lift/arc there are modulatio and i can weld.Lift arc /hf switch on the panel
Oh, its just for test. Its doesn't matter where the switch are in mode. Stil no welding power or HF.Top/left selector is on remote.
I will test it later. Ac in mma mode?Ac is working on tig and mma?
