Hi all
I've got a Heliarc HF250 plus tig welder that I need its circuit diagram in order to repair it, suddenly it doesn't work when I try to weld tig. welding stick elctrode works fine. I've checked the handle microswitch and it works fine, too. so, it seems that the problem is in the machine.
Thanks for your help.
