Power LED faults
The ON/OFF power switch is set to ON (I),
but the power ON LED does not illuminate.
Make sure the power cord is plugged into the receptacle.
Make sure the power is on at the main power panel or at the disconnect-power switch box.
Make sure the line voltage is not too low (more than 15% below the rated voltage).
The power ON LED blinks.
Have an electrical technician check the incoming power. The input line voltage is either too high or
too low (a variance greater than ±15% of the rated voltage). See Hypertherm system ratings on
page 17 and Prepare the electrical power on page 25.
All four LEDs blink when the system is powered ON.
A qualified service technician must service the system. Contact your distributor or use the
