xmt prepower check igbt

[Gmoney44]

I am trying to do the prepower check on some xmt 350s and I am unfamiliar with what they are looking for me to do with the igbt testing (circled in picture). Also I only have a multimeter so any help would be appreciated

Those are additional tests you can perform if you have an IGBT tester. You can make a simple one with a 9v battery an LED, and a couple resistors.

Thanks for reply.. Ok thats what I thought I would need a ibgt tester but was hoping I could get away with using something else. Well guess I'll be getting a igbt tester bc I have 8 of these to work through.
Is it simply enough you could tell me how to do a test once I have a igbt tester?

Is a cheap tester like this something that would be able to do the job?https://www.ebay.com/itm/372864022690

The service manual for the Hypertherm 85 has a section on testing the IGBT
using the Hypertherm tester as well as a home made one.

The schematic f0r the home made tester is included.
