Technical data
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.
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.
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.
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 out-
put must be reduced accordingly.
