3.5 Thermal protection
Cutting power source is equipped with a thermal switch at the radiator fin of IGBT to monitor the
temperature.
When the abnormal temperature happens, the thermal switch takes action and cut off the output.
Please be sure not to use under the conditions listed here:
•Over the rated output voltage
•The air inlet or outlet is blocked
•The ambient temperature is higher than 40 °C
•The cooling fan stops
3.6 Cooling fan stop function
Cooling fan can stop to save energy and machine runs into energy saving state 7 minutes after the
cutting machine remains in the stand-by state.
Cooling fan starts immediately after the power switch is turned on.
Once cutting operation restarts, the cooling fan rotates again.
