Amperage adjustment knob
Set this knob to the gas test position (fully counter-clockwise) before adjusting the gas pressure with
the pressure regulator knob on the top of the power supply. Once the gas pressure is set, turn the knob
clockwise to set the output amperage. The torch will not fire when the knob is in gas-test position.
Mode switch and leds
The mode switch can be set in one of three positions:
• Continuous pilot arc to cut expanded metal or grate (top).
• Non-continuous pilot arc to cut metal plate (middle).
• Gouging (bottom).
After you change the mode switch, verify that the gas pressure is still set correctly. Different modes of
cutting require different pressure settings.
