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
