Can anyone help, I have a Kempi Minarc 200 stuck on 15 amps. What can be the problem, little used outside of the guarantee, maybe I should have bought cheaper Chinese!

>>21210863 I understand this is a MinarcTig Evo 200? This indicates a motherboard fault. A problem with the control chip detecting the status of the welder, a fault with the output voltage measurement, etc.

Thanks for the response, careless mistake, it is a Kemppi Evo Minarc 180 MMA welder. Would the same diagnosis apply?

>>21212059 Similarly, however, this indicates that one of the IGBTs in the dual forward inverter module is likely to be damaged. If this is the case, the only remaining option is to replace the entire Z001 board.
