Dear CNC ZONE community,

I am an owner of a Hypertherm unit, for plasma cutting.

My consummables wear out quickly, and when I checked the operator manual they reffered to the low compressed air pressure as the fault. error code "44

I checked the solenoid valve
It seems fine and I changed some of them to no avail.
Then another error appears, which is 21.
I chose the consumable parts to no avail, and I'm still facing problems.
When the operation starts, the torch goes out and the voltage appears on the screen well for a moment and then stops.
When examining the electrode after the experiment, I saw it ignited in a black color from the side of the head.
Is it possible for experts to help me
Thank you for your cooperation

I would check to make sure that your cvompressed air is clean & dry
