Adjust the gas pressure
Look at the gas pressure LED. If it illuminates green in the center of the pressure bar, the incoming
gas pressure is correct for the mode you have selected. If the LED illuminates yellow, either above
or below the center, the gas pressure needs to be adjusted.
To adjust the pressure:
1. Turn the amperage knob counter-clockwise to the gas-test position as show below.

Set the mode switch
Use the mode switch to select the type of work you will be doing:
To cut expanded metal or grate cutting (top position). Use
this setting to cut metal with holes in it or for any job that
requires a continuous pilot arc. Leaving the mode switch
on this setting to cut standard metal plate will reduce
consumable life.
To cut metal plate (middle position). Use this setting to cut
metal up to 1-inch (25.4 mm) thick or pierce metal up to
1/2-inch (12.7 mm) thick.
Gouging (bottom position). Use this setting to gouge metal.
Leaving the mode switch on this setting while cutting results
in poor cut quality.
