HELP: Hypertherm PMX85 3-43-0 Error (0-19)

[Ianb007]

Hello,
Hoping someone can help or maybe had the same issue:

I get a 0-19 error on my plasma. When I go into the error menu it shows the 3-43-0. I contacted Hypertherm Tech Support.
Changed out the capacitors to new ones - same error.
Changed out the Inverter IGBT - same error

Now when I do the Resistance test between the test points I get 24kOhm on both sets, but when I switch my black and red leads around I get 18kOhm.

DC-DC Flyback test passed.

Hypertherm Tech support is taking a couple days to get back to me.

I can switch out the board or PFC IGBT but don't want to spend all this money and still have this error.

Anybody had this error or suggestion as to what replace next?

Yikes, that's a tough one. May be forced to wait on Hypertherm for that one, pretty deep...

It sounds like you may end up having to take it into your local Hypertherm dealer for diagnostics. I would think they can test these boards and replace the faulty one as required.
