2.2 Duty cycle

• The rated duty cycle for this product is 40%.
• Using this product at any usage rate over the rated rate
of use may cause the increase of equipment temperature
over the permissible maximum, and result in the deterio-
ration or burnout of the equipment.
• Set the output current (A) at the pulse welding to an
average value between the pulse current and the weld-
ing current.
• When using the product in combination with other
devices, such as the welding torch, etc., use it at the low-
est rated rate of use in those devices

• "The duty cycle is 40% at the rated output" means for 40
percent of the ten-minute period (4 minutes), the power
source can maintain operation with the rated welding
output without overheating. The remaining six minutes
must be operated at no-load to allow proper cooling.
Calculation formula:
(4 minutes/10 minutes) x 100% = 40%
• When using any output current different from the rated
output current, obtain the permissible rate of use from
the following calculation formula.
• (The rated output current of this product: 300 A)
• Allowable duty cycle (%) =

(
Actual output current
Duty cycle: he 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, how-
ever, it means when driving it at the rated number of
revolution.
