Adjust the gas pressure manually

The system sets the gas pressure for you, but you can adjust it.

Make sure that the gas pressure you select is correct for your cutting or gouging application.

  1. Move the torch-lock switch to the green "ready to fire" position.
  2. Push and hold the Mode button.
  3. While holding the Mode button, turn the adjustment knob to adjust the gas pressure to the necessary level.

    In this example, we decreased the gas pressure to 2.4 bar (35 psi).

    The image shows the user controls on the plasma power supply where the mode button and adjustment knob are located.

    In many conditions, you can increase and decrease the gas pressure by a maximum of 0.7 bar (10 psi). The acceptable range can change if the cartridge you are using has a smaller maximum limit.

  4. Release the Mode button.
  • After you release the Mode button, the AMPS Light Emitting Diode (LED) illuminates again, and the 2-digit display changes from gas pressure back to amperage.
  • The selected mode LED flashes to let you know that the gas pressure has been manually adjusted. It continues to flash until you set the pressure back to default.
The image shows the controls with an arrow pointing to the AMPS Light Emitting Diode.

To see the gas pressure setting again, push and hold the Mode button.
