Technical data
Explanation of
the term "duty cy-
cle"
Duty cycle (D.C.) is the proportion of time in a 10-minute cycle at which the device may be
operated at its rated output without overheating.
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.
- Welding phase = 60% of 10 minutes = 6 minutes
- Cooling phase = remaining time = 4 minutes
- After the cooling phase, the cycle begins anew.
If the device is to be continuously operated without stopping:
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.
Special voltages For devices designed for special voltages, the technical data on the rating plate applies.
For all machines with a permitted mains voltage of up to 460 V: The standard mains plug
allows the user to operate with a mains voltage of up to 400 V. For mains voltages up to
460 V fit a mains plug permitted for such use or install the mains supply directly.
