anybody know where i could get some tech info about my smith plasma cutter?

[WDixon27]

it died saturday and it seems that smith hasn't delt with plasma cutters in a few years, the overload light stays on and letting it sit on/off and plugged/unplugged doesn't reset it and i see no kind of external breaker or fuse, haven't had time to pop the top and investagate further, it's a pp-25 smith 220 volt unit
