Ask the mods to move this to the Hypertherm area, you'll probably get an answer there. You can also private message Jim Colt, he's a manager at hypertherm and pretty active here.

Welcome, by the way :waving:

 

Moved.

 

Well I'm new to this. How or who is the mods that I need to ask to move this to Hypertherm?

 

Sorry dellwas, I see now that it was already moved. Thanks anyhow.

 

Not a prob... I suspect Jim Colt will be along shortly, if not send him a PM (Private Message). Don't be scared to ask if you don't know how.

 

Lets see, needs power pcb and both IGBT. Must have a burnt part just above the right IGBT and if you check the transistor on the heat sink above that, at the top of the pcb, you should find it shorted. seen a few with this problem. fixed when in warranty and whole machine got replaced when out. worked with Hypertherm rep on a trade in.
the right hand(PFC) IGBT is not just an IGBT there is more to it. The left one (inverter) IGBT is a standard IGBT block of two. Good luck finding anybody who will attempt to fix this power pcb, If not repaired right the IGBTs could fail again and damage the pcb and more.

 

Thanks. for the info. I did see one burnt part on the board, probably a transistor, but did not see any thing else bad but then I don't know what I'm looking for. Probably will end up selling for parts and look for another.

 

If the Powermax1000 appears in good condition and torch looks decent...it is worth $1500 to $1700. It is a great plasma cutter and better than most new ones in its power range today. You can download the service manual at www.hypertherm.com , click on downloads library at the top of the page. A new power board is in the $800 range.....and well worth it if the rest of the unit is good.

L2 and R98 should be burnt and Q2 should test shorted. 0 ohms to any pin.
If anything else is burnt then it is a different problem.

 

Thanks Jim. The unit looks good and the torch looks real good. I will download the service manual and go from there.

Thanks again.
