LIGHTS | CONDITION | SUGGESTIONS |
|
|
|
MACHINE ON | Should always be on when machine is on. | Normal |
|
|
|
OUTPUT ON | On when there is voltage potential at the | Normal |
| torch (cutting or pilot). |
|
| OUTPUT ON is blinking alternately with |
|
| AIR PRESSURE when power is first | There is a problem with the microprocessor, |
| applied to machine. | replace the Control PC board. |
| If OUTPUT ON is blinking alternately |
|
| with MALFUNCTION, the pilot arc duty |
|
| cycle is exceeded. | Wait for machine lights to stop blinking. |
|
|
|
AIR PRESSURE | On whenever the air pressure is above 45 | Normal conditions are purge, preflow, |
| psi (311 kPa), there is an error condition | postflow and cutting. |
| mentioned above where air will turn on. |
|
| The air will turn on for a brief time when |
|
| power is first applied to machine. |
|
|
|
|
THERMAL | Should normally be off. | If on, wait for machine to cool down. |
|
| Machine will cool faster if left on with |
|
| output off. |
|
|
|
MALFUNCTION | Light on. At end of preflow, machine | Check consumables, replace as needed. |

| Light blinking. If cutting tried with air | No air connected to machine, air pressure |
| pressure less than 45 psi (311 kPa) then | set too low, or air leak in system. |
| the machine will wait for air pressure to |
|
| become greater than 45 psi (311 kPa). |
|
| Light blinking alternately with OUTPUT | Pilot arc duty cycle has been exceeded. |
| ON. | Wait for machine lights to stop blinking. |
| Light started blinking during cutting or | If cutting or gouging with standoff more than |

| trigger and resume cutting or gouging. | or use drag cup. Check consumables to see if |
|
| electrode melted to nozzle. |
| Light blinking with THERMAL light on. | Wait for machine to cool. Torch assembly is: |
