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 generator 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 generator works at mains voltages differing by
+/-20% from the rated mains (400V rated, Minimum
voltage 320V, maximum voltage 480V).

CONNECTION
- Before making the electrical connections between
the current generator 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.

LIFTING POWER SUPPLY
WARNING :
The machine TIG µP 293H weighs 42,5Kg.
The machine TIG µP 403H weighs 50 Kg.
Lifting by hand:
Lift the machine using the two handles provided
.
The Inverter TIG µP 293-403H
AC/DC is supplied equipped
with a coupling for connection
to the A.W.C. water cooler.
N.B.) To start the A.W.C. water
cooler it is necessary to switch
both the welding machine and
the A.W.C. water cooler on.
