3 – Basic System Operations

Manually adjusting the gas pressure

For normal operations, the power supply automatically adjusts the gas pressure. If you need to adjust the gas pressure for
a specific application, you can use manual mode to do so.



Manual mode should be used by experienced users who need to optimize the gas setting
(override the automatic gas setting) for a specific cutting application.

When you switch from manual mode to automatic mode, the power supply automatically sets the gas pressure, and the
amperage setting is unchanged. When you switch from automatic mode to manual mode, the power supply remembers
the previous manual gas pressure setting, and the amperage setting is unchanged.

When you reset the power, the power supply remembers the previous mode, gas pressure, and amperage settings.

To adjust the pressure:

1.

Press the automatic/manual pressure setting mode selector so that the LED next to the selector illuminates. Refer to

Front controls and LEDs

2.

Press the current/gas selector until the selection cursor is opposite the gas pressure setting in the status screen.

3.

Turn the adjustment knob to adjust the gas pressure to the desired level. Watch the arrow in the pressure bar as you
adjust the pressure. (See

Gas pressure indicators

Adjusting the current (amperage)

Turn the adjustment knob to adjust the current for your particular cutting application.

If the system is in manual mode, do the following to adjust the amperage:

1.

Press the current/gas selector until the selection cursor is opposite the amperage setting in the status screen.

2.

Turn the adjustment knob to change the amperage.

3.

If you wish to exit manual mode, press the automatic/manual pressure setting mode selector. The LED goes off.



When you exit manual mode, the gas pressure resets to the factory-optimized value.

When you switch between manual mode and automatic mode, the power supply retains the amperage setting. When you
reset the power, the power supply returns to the previous mode (automatic mode or manual mode) and remembers the
previous amperage setting.
