Hello
I have a broken Kemppi MinarcTig Evo 200 Tig welder.
I have measured the IGBT and rectifier module to be OK. The DC bus and control board is also OK
The problem seems to be that the IGBTs are not switching, as there is no output of the welder. There should be a 16V voltage to the IGBT drivers but the service schematic I have obtained seems to be of an older version, I can't seem to find the correct measuring points.
Does anybody have an updated service schematic of this model (newer than 2015 service manual)
Or has anybody looked at these machines before
