INSTALLATION
WARNING
This
Class A
equipment is not intended for use in
residential locations where the electrical power is
provided by the public low-voltage supply system.
There may be potential difficulties in ensuring
electromagnetic compatibility in those locations,
due to conducted as well as radiated disturbances.
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 good operation of the Power Source is
ensured by correct installation; you must therefore
proceed as follows:
- Position the machine in such a way that there is
no obstacle to the air circulation ensured by the
internal fan since the internal components require
suitable cooling.
- Ensure that the fan does not send deposits or
dust into the machine.
- Avoid impacts, rubbing, and – absolutely
- exposure to dripping water, excessive heat
sources, or any abnormal situations.
MAINS VOLTAGE
The Power Source works at mains voltages
differing by +/-20% from the rated mains (230V
rated, Minimum voltage 184V, maximum voltage
276V).

CONNECTION
- Before making the electrical connections between
the current Power Source and the line switch,
ensure that the switch is turned off .
- The distribution panel must comply with the
regulations in force in the country of use.
- The mains system must be of the industrial type.
- Provide a special socket which can receive leads .
- For longer connecting cables, increase the lead
section as required.
- Upstream, the mains socket must have a suitable
switch provided with delayed fuses.
- In the event of breakage of the power cable, it must
be replaced at a qualified assistance centre.
EARTHING
- To ensure user protection the welding machine
must absolutely be correctly connected to the earth
system
(INTERNATIONAL
SAFETY
REGULATIONS).
- It is indispensable to provide good earthing by
means of the yellow-green lead in the power cable,
in order to avoid discharges due to accidental
contacts with earthed objects .
- The chassis (which is conductive) is electrically
connected with the earth lead; if the equipment is
not suitably connected to earth it may cause
electric shocks which are dangerous for the user.
INSTRUCTION FOR
INSECURE POSITIONING
Failure to properly secure the machine can cause
personal injury.If machine is in an insecure position
do not attempt to switch on.Do not put the machine
on an unlevelled surface greater than 10°.
PREPARING FOR
ELECTRODE WELDING
(MMA)
1) Follow the indications given above for primary
connection and installation.
