Duty Cycle; Dimensions - Panasonic YD-350GL4 Operating Instructions Manual

2.1.2 Duty cycle for
The rated duty cycle for this product is 60%.
●
"The duty cycle is 60% at the rated output" means that
for 60 percent of the ten minute period (6 minutes), the
power source can maintain operation with an output of
350A without overheating. The remaining four minutes
must be operated at no-load to allow proper cooling.
When using the product in combination with other
●
devices, such as the welding torch, etc., use it at the
lowest rated duty cycle among those devices
Note
Using a product at a duty cycle over the rated duty
cycle may cause the
temperature over the permissible maximum, as a result,
the lamp to indicate the "abnormal rise in temperature"
is turned on.
IGBT, DCL and some diodes of this unit are protected
●
with "Thermal protector". The error "Err 3: Abnormal
rise in temperature" occurs when the temperature of
those units exceeds the allowable temperature.
For your reference:
Duty cycle: The percentage ratio of loading time to full time. A cycle of the full time shall be 10 minutes.
Rated duty cycle: means the rate of use when loading the rated output current intermittently at the rated input
voltage of the rated frequency. Regarding the engine-driven welding power unit, however, it means when driving it at
the rated number of revolution.
