
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.
