Generator-Powered Operation
Generator-
powered opera-
tion 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 for 3-phase
devices as follows:
S
1max
= I
1max
x U
1
x √3
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!
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.
