rules for the installation of earth-leakage circuit
Caution
breakers (RCD) have to be respected, and operation
requires an installed breaker.
Generator or mains power fuse protection should be 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 315
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.
