Electrical connection
For construction site distribution boards observe the regulations about the FI protective switch
and only operate the welding device over an FI switch (Residual Current Device, RCD).
Ensure that the mains power network or power generator is fused using fuses of a maximum of
20 A (time-lag).
Only appropriately use approved and registered extensions cables with the following conductor
cross-sections.
up to 20 m:
more than 20 m:
The extension cable may only be used when unrolled completely and stretched to avoid over-
heating.
The required power generator nominal output is dependent on the highest power consumption of
the fittings used. Furthermore, the ambient conditions as well as the performance data of the
power generator itself should be taken into account when constructing the connecting conditions
on-site.
The nominal power output of a single-phase power generator is 220 – 240 V, 50/60 Hz:
d 20 - d 160 .............. 3,2 kW
d 160 - d 400 ............ 4 kW mechanically regulated
d > 400 ..................... 5 kW electronically regulated
The power generator must be switched on first before the welding equipment can be attached.
The open circuit voltage should be regulated at about 240 volts.
Note: No other consumer should be driven by the same power generator while
welding!
After finishing the welding work, first separate the device connector plug from the power genera-
tor, then switch this off.
