The power source is generator-compatible.
The maximum apparent power S
1max
of the power source is required for dimensioning the
necessary generator output.
The maximum apparent power S
1max
of the power source is calculated as follows:
S
1max
= I
1max
x U
1
I
1max
and U
1
according to the device rating plate and technical data
The generator apparent power S
GEN
needed is calculated using the following rule of
thumb:
S
GEN
= S
1max
x 1.35
A smaller generator can be used when not welding at full power.
IMPORTANT! The generator apparent power S
GEN
must not be less than the maximum
apparent power S
1max
of the power source!
When single phase devices are being operated with a 3-phase generator, note that the
stated apparent power of the generator is often just the total that can be present across all
three phases of the generator. If necessary, obtain further information about the single-
phase power of the generator from the generator manufacturer.
NOTE!
The voltage delivered by the generator must never fall outside of the mains voltage
tolerance range.
The mains voltage tolerance is specified in the "Technical Data" section.
