Technical Data; Explanation Of The Term "Duty Cycle - Fronius TransPocket 150 Operating Instructions Manual

Technical data

Explanation of Duty cycle (D.C.) is the proportion of time in a 10-minute cycle at which the device may be

cle"
The D.
C. values specified on the rating plate are based on an ambient temperature of 40°C. If the
ambient temperature is higher, either the D.C. or output must be reduced accordingly.
Example: Welding at 150 A at 60% D.C.

NOTE!
Welding phase = 60% of 10 minutes = 6 minutes
Cooling phase = remaining time = 4 minutes
After the cooling phase, the cycle begins anew.

look in the technical data for a D.C. value of 100% for the reigning ambient tempera-

Reduce the output or amperage in line with this value so that the device can remain in
use without observing a cooling phase.
