4 indicator LEDs, and a gas pressure LED, which are described below.
front controls and leds
Temperature led (yellow)
When illuminated, this LED indicates that the power supply temperature is outside the acceptable range.
Torch cap sensor led (yellow)
When illuminated, this LED indicates that the consumables are loose, improperly installed, or missing.
For information on the possible fault conditions, refer to the Troubleshooting guide topic in the
Troubleshooting and System Tests section. If this LED illuminates, the power must be turned OFF, the
consumables installed properly, and the system turned ON again to reset it.
fault led (yellow)
When illuminated, this LED indicates that there is a fault with the power supply. Some fault conditions
will cause one or more of the LEDs to blink. For information on what these fault conditions are and how
to correct them, refer to the Troubleshooting guide topic in the Troubleshooting and System Tests
section.
AC
Power oN led (green)
When illuminated, this LED indicates that the power switch has been set to I (ON) and that the safety
interlocks are satisfied.
gas pressure led and pressure bar (yellow/green)
When the LED indicator in the pressure bar illuminates green and is centered in the vertical bar, the gas
pressure is set correctly for the mode of cutting selected with the mode switch. If the pressure is too
high for the selected mode, the indicator in the pressure bar will be above the mid-point of the bar. If
it is too low, the indicator will be below the mid-point. At the highest and lowest points on the bar, the
indicator will illuminate yellow.
If the indicator is at the lowest part of the bar and is flashing, then the gas pressure is less than the
minimum required pressure.
