Hey guys,

Im using plasma cutting system Hypertherm MAXPRO 200 and I have met with this problem. While plasma was running (cutting) it suddeny break down, with no system error report.
After this break down im not able to run again MAXPRO 200. It turns out to be the motherboard, so we replace it but after few minutes of cutting it happened again.
The breakdown happened while plasma was cutting sheet metal 8mm thick. Adjustment was following: Ampere= 80 A, Air pressure= 90 PSI, Voltage= 140 V.

I will appreciate any advice.

Thanks
