1. For optimum system performance, make sure that the inlet gas pressure stays between 7.6 bar – 8.3
bar (110 psi – 120 psi) while gas is flowing.
Never use more than the maximum gas pressure of 9.3 bar (135 psi).
2. Which fault code do you see?
0-12-1 Increase the inlet gas pressure from the gas supply source.
0-12-2 Decrease the inlet gas pressure from the gas supply source.
0-12-3 Adjust the inlet gas pressure from the gas supply source as necessary.
3. Make sure that the gas lines do not have kinks, blockages, or other damage.
4. Do a gas test to find if the plasma power supply's actual output gas pressure is lower than the set
pressure by more than an acceptable quantity.
