2.9 Power Supply Specifications
2.9.1

Mains Power Supply

Utility suppliers' wiring requirements, occupational safety
rules, applicable standards, and national codes have to be
respected.
When using power distributions on the worksite,
rules for the installation of earth-leakage circuit
Caution
breakers (FI) have to be respected, and operation
requires an installed breaker.
Generator or mains power fuse protection should be max.
16 A (slow blow). The product has to be protected against
rain and humidity.
2.9.2

Generator Power Supply

The required nominal generator capacity as determined
by the power supply requirement of the largest fitting to
be welded depends on the power supply specifications,
the environment conditions, and the generator type itself
including its control/regulation characteristics.
Nominal output power of a generator 1-phase, 220 - 240 V,
50/60 Hz:
d 20.....d 160
d 160 ....d 450
Start the generator first, then connect the welding unit.
The idle voltage should be set to approx. 240 volts. When
turning the generator off, disconnect the welding unit first.
The working output power of the generator de-
creases by about 10% per 1,000 m of altitude.
During the welding process no other device con-
Important
nected to the same generator should be operated.

2.10 Integrity of Welding Reports in Memory

When transferring welding reports to a USB stick, always
be sure to wait until the display shows the "Download
finished" message before you disconnect the USB stick
from the product. If you disconnect it too early, the unit
may ask you whether you want to delete the reports in
memory, although they were not properly transferred. In
this case, if you delete the contents of the report memory,
the welding reports would be irrevocably lost and would
not be available elsewhere either.
