Generator-Powered Operation
Required gener-
ator output
The power source is generator-compatible.
The maximum apparent power S
1max
of the power source must be known in order to
select the correct 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 or 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 may be used when not welding at full power.
NOTE!
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 three-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.
