DUTY CYCLE
A rated duty cycle 50% means to use the rated welding current for 5 minutes out of 10 minutes
and suspend operation for remaining 5 minutes.
If the rated duty cycle is exceeded, a temperature increase value tops the maximum allowable
temperature of the equipment and the equipment may be deteriorated or burnt out.
The figure above shows the relations between the welding current and duty cycle for the
YD-200KR2/-350KR2/-500KR2 welding current value and use the equipment within that range.
When using in combination with other device such as welding torch, etc. use at the lowest
duty cycle reactor of each device.
