Technical Data; Explanation Of The Term "Duty Cycle; Special Voltages - Fronius TPS/i COMPACT Operating Instructions Manual

Technical data

Explanation of Duty cycle (ED) is the proportion of time in a 10-minute cycle at which the device
the term "duty may be operated at its rated output without overheating.
cycle"
NOTE!
The ED values specified on the rating plate are based on an ambient temperat-
ure of 40 °C.
If the ambient temperature is higher, either the ED or output must be reduced
accordingly.
Example: Welding at 150 A at 60% ED

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.

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

Look in the technical data for a ED value of 100% for the current ambient
temperature.
Reduce the output or amperage in line with this value so that the device can
remain in use without observing a cooling phase.
