About "Duty cycle"
Duty cycles are based on a ten minutes time interval.
If the duty cycle is 100 % at rated output, that means the
unit is capable of performing continuous operation at the
specified installation environment.
• In case of using the machine in combination with
other products, such as welding torch, please apply
the lowest rated duty cycle among the applied prod-
ucts.
• Duty cycle at 40 °C is calculated based on simula-
tions.


The welding power source is equipped with thermal switch
at the radiator fin of the semiconductor to monitor the
temperature.
The thermal switch is turned on and stops the output when
the welding power source becomes an abnormal elevation
of temperature due to over-duty cycle or over-rated output
current, or declining cooling effect.
