Duty Cycle; Dimensions - Panasonic YC-300BZ3YHD Operating Instructions Manual

2.2 Duty cycle


The rated duty cycle for this product is 100%.
"The duty cycle is 100% at the rated output" means that
the power source can maintain operation continuously
with the rated output current without overheating.

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 increase the equipment temperature over the
permissible maximum, which cause the error (Err-
13).
* When an output other than rated value is used.

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.
