Have a Maxstar 300 with a P-8 code had it checked out at the repair center
and it has a bad front panel control board.
It's wired 220 single phase and it 's only ever been used for TIG welding mostly low amp welds with a water cooled torch.
When it stopped working I had just finished tacking a part at about 60 amps
pressed the pedal ( wireless) to weld and that's when the error code appeared.
Tried restarting several times same result.
Never had a problem sense new and always serviced yearly.
I have been told the board has obsolete parts by Miller and there isn't any support
from them.
Inovat circuit board repair wouldn't touch it.
The serial # LE024183.
So question is, scrap or what?
