(-) welding socket.
VENTILATOR. The ventilator is turned on only during the
welding phase, at the end of this phase it remains turned
on for a pre-established period of time according to the
welding conditions. However, the ventilator is checked by
special thermal sensors that guarantee the correct
cooling of the machine.
THE MACHINE CAN ALSO BE CONNECTED TO
ENGINE-DRIVEN GENERATORS AS LONG AS THEY
HAVE A STABILIZED VOLTAGE.

INSTALLATION
WARNING: This equipment does not comply with IEC
61000-3-12. If it is connected to a public low voltage
system, it is the responsibility of the installer or user of
the equipment to ensure, by consultation with the
distribution network operator if necessary, that the
equipment may be connected.
The generator in question must be supplied with a rated
voltage of 3X400V~±15%/50-60HZ.
Connect the generator to the mains supply and position
the switch to the "I"/"ON" position, and the welding
