PART TO BE WELDED
The part to be welded must always be connected to earth in or-
der to reduce electromagnetic emission. Much attention must
be afforded so that the earth connection of the part to be weld-
ed does not increase the risk of accident to the user or the risk
of damage to other electric equipment.
When it is necessary to connect the part to be welded to earth,
you should make a direct connection between the part and the
earth shaft. In those countries in which such a connection is
not allowed, connect the part to be welded to earth using sui-
table capacitors, in compliance with the national regulations.

Maintenance

ATTENTION: before carrying out any inspection of the inside
of the generator, disconnect the system from the supply.
SPARE PARTS
Original spare parts have been specially designed for our equi-
pment. The use of non-original spare parts may cause varia-
tions in performance or reduce the foreseen level of safety.
We decline all responsibility for the use of non-original spare
parts.
GENERATOR
As these systems are completely static, proceed as follow:
• Periodic removal of accumulated dirt and dust from the inside
of the generator, using compressed air. Do not aim the air
jet directly onto the electrical components, in order to avoid
damaging them.
• Make periodical inspections in order to individuate worn ca-
bles or loose connections that are the cause of overhea ting.

Possible problems and remedies

The supply line is attributed with the cause of the most com-
mon difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage.
2) Check that the power cable is perfectly connected to the
plug and the supply switch.
3) Check that the power fuses are not burned out or loose.
4) Check whether the following are defective:
• The switch that supplies the machine.
• The plug socket in the wall.
• The generator switch.
NOTE: given the required technical skills necessary for the re­
pair of the generator, in case of breakdown we advise you to
contact skilled personnel or our technical service department.
Procedure for welder assembly
and disassembly
Proceed as follows (see Fig. E):
• Unscrew the screws that secure the cover to the front panel,
rear panel and base.
• Remove the cover from its seat.
Proceed the other way round to re-assemble the welder.
