2.2 Rated duty cycle
■
YD-350FD2
●
The rated duty cycle is 60 %. This means that the machine can cut for a total of 6 minutes out of any 10 minutes at the
rated current, and then, during the remaining 4 minutes, the machine must be cooled down to prevent overheating.
●
Exceeding allowable duty cycle can cause the temperature rise higher than the maximum allowable temperature,
resulting in the performance degradation or damage.
●
The figure above shows the ideal value of cutting current and duty cycle. Please use the machine within the
corresponding duty cycle of cutting current.
■ YD-500FD2
●
The rated duty cycle is 60 %. This means that the machine can cut for a total of 6 minutes out of any 10 minutes at the
rated current, and then, during the remaining 4 minutes, the machine must be cooled down to prevent overheating.
●
Exceeding allowable duty cycle can cause the temperature rise higher than the maximum allowable temperature,
resulting in the performance degradation or damage.

The figure above shows the ideal value of cutting current and duty cycle. Please use the machine within the
corresponding duty cycle of cutting current.
2.3 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.
