Help Needed - Hypertherm 1250 Toasted IGBT

[adshaft]

I was wondering if anyone can help me out. I just bought a used "damaged" Hypertherm 1250. The previous owner had cut something outside with it and left it outside for a bit before he realized that a little rain/snow had fallen and by that time, it was too late. The unit got shorted out. Now I'm no welder nor have I ever used a plasma cutter, but I'm practicing with my MM200. I bought this unit cause of it's reputation and for $300 CDN I figure I'll take that gamble in fixing it. Now from what I can see the IGBT module (inverter) got fried. I can't make out the label, from what I can see it's a Fuji 2MBI1????140 150A 1400V Japan O.

Which one of these if any is the same unit?

Now moving on to the circuit board, (not an electrician so bare with me) I can see that there was damage to the copper foils. I was planning on soldering in some new foil to bring it to it original state or close to it. I included a Photoshopped photo of how it would be once done. The short also caused a couple wires (yel & blk) ones to the right of the IGBT to burn, will solder in some new ones. I also noticed those three round small whatever they are, had seen better days and 2 are cracked. Don't think it had anything to do with the short, but would need to be replaced. Once all these thing are done I'll bring it to one who knows electronics and have him tell me if anything else needs replacing (diode etc...)

If anyone can kindly tell me what model# the IGBT inverter is, and what the model # for those three round things are, I 'd be most appreciative.
