Hi
I am using powermax 65 plasma and it works fine for two weeks, but now I am getting error code 0-12 and 0-20 continuously.
When I arc starts it cuts for a second or less before the arc is gone and one of the above error codes appears.
I replaced the consumables with new ones, checked the air inlet pressure, checked the filter but everything was ok.
But there was a noice of air flowing out of the air regulator inside the plasma. I opened the plasma cover and I gave arc start signal and I have seen that almost all the gas was blown out of the regulator valve. I repeated the start signal and I found that both solenoids lying above the regulator are enabled and disabled together (both LEDs light at the same time when the arc starts). I noticed that one of them is DUMP valve and the other is the FILL valve. I think that the DUMP valve should not be enabled so as not to blow the gas out and prevent it from flowing to the torch. Is that right? Could it be a wrong signal from the regulator controller?
Attachment 316248
By the way, when both solenoids are disabled the exhaust of the valve still blows little gas flow.
Could any one please help me with this issue?
Thanks in advance
