Minimum inlet pressure and gas flow rate
Make sure that your worksite complies with the minimum gas flow rate and inlet gas pressure requirements for the cutting, gouging, and marking processes.
| Process | Minimum gas flow rate and inlet pressure |
|---|---|
| Cutting (20 A – 45 A) | 212.4 slpm (450 scfh) at 5.9 bar (85 psi) |
| Gouging (20 A – 45 A) | 212.4 slpm (450 scfh) at 4.8 bar (70 psi) |
| FineCut® Marking (9 A – 19 A) | 141.6 slpm (300 scfh) at 4.1 bar (60 psi) |
You can adjust these pressures for different conditions that are specific to your environment.
Additional gas filtration installed between the gas supply and the plasma power supply can have an effect on gas pressure and gas flow. Speak to the filter manufacturer about gas pressure requirements. Hypertherm® recommends that you install an inline pressure gauge at the gas inlet on the rear of the plasma power supply. Use this gauge to monitor the gas pressure at the plasma power supply, after all external filtration.
