Need help with my chinese plasma cutter!!

[Wise john]

Greetings to everyone....i bought an lgk -100IGBT from a chinese distributor.my problem is;
-During cut the plasma suddenly goes of and move along the path of cut without cutting and if am lucky it cut the next design.

-And using sheetcam to generate my g-code .but during simulate i discover it stops at one point .i am unable to figure out where exactly the problem is coming from(sheetcam doesn't show any error sign after u click plasma cut)
I will gladly embrace your contributions

Hi John, those cutters are pretty good, but probably you have recieved it with the cheap P80 torch which makes the trouble.

Any error lights come on if it has any?

OK, I am not familiar with that plasma, it may not even have any but I thought I would ask first.

Do you have an air pressure gauge at the back of the plasma cutter to monitor input pressure when this problem happens?
