device
Overview with critical raw materials:
An overview of which critical raw materials are contained in this device can be found at
the following Internet address.

To calculate the year of production of the device:
- Each device is provided with a serial number
- The serial number consists of 8 digits - for example 28020099
- The first two digits give the number from which the year of production of the device
can be calculated
- This figure minus 11 gives the year of production
• For example: Serial number = 28020065, calculation of the year of production =
28 - 11 = 17, year of production = 2017
Special voltage For devices designed for special voltages, the technical data on the rating plate applies.
Explanation of
the Term Duty
Cycle
The duty cycle (D.C.) is the period of a ten minute cycle in which the device may be
operated at the stated power without overheating.
NOTE!
The D.C. values cited on the rating plate relate to an ambient temperature of 40 °C.
If the ambient temperature is higher, the D.C. or power must be lowered accordingly.
Example: Welding with 150 A at 60% D.C.
- Welding phase = 60% of 10 mins = 6 mins
- Cool-down phase = rest time = 4 mins
- Following the cool-down phase, the cycle begins again.
