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

NOTE!
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.

during operation: -10 °C to +40 °C (14 °F to 104 °F)
during transport and storage: -20 °C to +55 °C (-4 °F to 131 °F)
recommended temperature range during charging: + 4 °C to + 40 °C (+ 39,2 °F to +
104 °F)
up to 50 % at 40 °C (104 °F)
up to 90 % at 20 °C (68 °F)
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-
ture.
Reduce the output or amperage in line with this value so that the device can remain in
use without observing a cooling phase.
