„ If more than one machine has to be used on the same piece,
or in any case on pieces connected electrically, the sum of the
no-load voltages on the electrode holders or on the torches
may exceed the safety levels. Make sure that an authorised
expert evaluates the conditions beforehand to see if such risk
exists and adopt the protective measures described in 7.9 of
the EN 60974-9 technical specification if required.
Additional warnings
„ Do not use the machine for purposes other than those
described, for example to thaw frozen water pipes.
„ Place the machine on a flat stable surface, and make sure
that it cannot move. It must be positioned in such a way as to
allow it to be controlled during use but without the risk of being
covered with sparks.
„ Do not lift the machine. No lifting devices are fitted on the
machine.
„ Do not use cables with damaged insulation or loose
connections.
„ Only use an extension lead when absolutely necessary and
providing it has an equal or larger section to the power cable
and is fitted with a grounding conductor.
„ Do not block the machine air intakes. Do not store the machine
in containers or on shelving that does not guarantee suitable
ventilation.
„ Do not use the machine in any environment in the presence of
gas, vapours, conductive powders (e.g. iron shavings), brackish
air, caustic fumes or other agents that could damage the metal
parts and electrical insulation.
Environmental conditions (EN 60974-1)
„ Use the machine with the following environmental conditions
only:
„ Ambient temperature between -10°C and 40°C;
„ Relative humidity of the air ≤ 50% at 40°C
„ Relative humidity of the air ≤ 90% at 20°C
„ The surrounding air must be free of dust, acid, gas or corrosive
substances, etc.
Storage
„ Ambient temperature between -20°C and 55°C.
„ Always use adequate measures to protect the machine from
humidity, dirt and corrosion.
Disposal
Do not dispose of this machine as normal household waste at
the end of its life cycle.
The user is responsible for disposing of this electrical equipment
in collection points designated for disposal and recycling of
electrical equipment or contact the shop where you purchased
the product. This provision only refers to disposal of the
equipment within the European Union (WEEE).
Description of the machine
The welding machine is a current source for manual Plasma arc
cutting, fitted with a torch with pilot arc.
The machine is built using electronic INVERTER technology.
The machine delivers a direct current output.
The electrical characteristic of the transformer is of the falling
type.

Assembly and electrical connections
„ Connections to the mains must be made by expert or qualified
personnel.
„ Make sure that the machine is switched off and disconnected
from mains before carrying out this procedure.
„ Make sure that the power socket that the machine is plugged
into is protected by safety devices (fuses or automatic switch)
and grounded.
¾Assemble the detached parts found in the packaging (Fig.5).
¾Check that the electrical supply delivers the voltage and
frequency corresponding to the machine and that it is fitted
with a delayed fuse suited to the maximum delivered rated
current (I2max) Fig. 3,1.
The requirements set out in the IEC/EN61000-3-12 standard
L
do not apply to this equipment. If this equipment is connected
to low voltage power supply network, either the installer or
the user is responsible for checking that this can be done
(consult the distribution system operator if required).
In order to comply with the requirements set out in the
L
EN61000-3-11 (Flicker) standard, it is advisable to connect
the welder to the supply network interface points having an
impedance lower than the reference Zmax = Fig. 3,4.
