Good afternoon. Such a problem, the pilot arc disappeared on my plasma cutter. On the pilot board 12 volts. The field effect transistor was ajar. Replaced it. I do not know where to dig. Do you have any ideas? I do not have an electrical scheme.

Hi,
did you checked these documentation please?

I learned this manual. My problem is not there. The air goes for two seconds, but the arc does not light up. then the air stops blowing and the diode lights up on the board. Tried to make less gap between the details. a working arc arises, but this is not correct.
