Gas flow rates
Refer to the cut charts starting on page 121 for flow rates specific to each cutting process
specified (based on the type of metal, the type of gas, and the output current).
Minimum inlet pressure (while gas is flowing)
The following pressure specifications apply for air, nitrogen, F5, and argon. Never exceed an inlet
gas supply pressure of 9.3 bar (135 psi).
You may need to adjust these pressures based on the equipment and conditions specific to your
environment. For example, additional gas filtration installed between the gas supply and the plasma
power supply may increase the required minimum inlet pressure. Consult the filter manufacturer.
Cutting
