Wanted: dead PMX1000 and 30XP boards

[MtnMann]

Anybody willing to sell old (bad) power boards from either a Powermax 1000 or a 30XP? I need some components and hoping to find donor boards.

If its just parts you need type the part number in on digikey and they most likely have it

Unfortunately not. The transformer is custom made for Hypertherm and some of the semiconductors are obsolete. Found many of them at Radwell but super expensive.

its not a big deal to find newer better igbt/mosfets and swap them in.
The transformers you are pretty hooped

The good thing about electronics is they all have pretty detailed datasheets.
Check voltage and current are the same or better, gate voltages need to be similar, rise same or a little faster, and make sure gate capacitance isnt more than the old ones.

Thanks!
