• The vrd (Voltage Reduction Device) can be activated, which
reduces voltages to below 12 V, which means that the weld-
ing machine can be used in ambient conditions in which there
is a high electrical risk, thereby providing maximum opera-
tor safety.
• An "Energy Saving" function that only activates ventilation
of the generator when necessary, making significant energy
saving possible and reducing maintenance, due to the small
quantity of dust and pollutantsthat are taken in.
• Can be connected to motor-powered generators of adequate
capacity providing high dependability - 16 kVA (MATRIX 2800
E-MG).
• Useable with power supply cables more than 100 m long.
• Reduced energy consumption.
• This generator also conforms to all the standards and direc-
tives in force in the European Community.

WARNING: This equipment complies with EN/IEC 61000-3-12 pro-
vided that the maximum permissible system impedance Z
than or equal to 0,059 Ω at the interface point between the user's sup-
ply and the public system. It is the responsibility of the installer or user
of the equipment to ensure, by consultation with the distribution net-
work operator if necessary, that the equipment is connected only to a
supply with maximum permissible system impedance Z
or equal to 0,059 Ω.
This system, tested according to EN/IEC 61000-3-3, meets the re-
quirements of EN/IEC 61000-3-11.

Usage limits (IEC 60974-1)

The use of a welder is typically discontinuous, in that it is made
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflush-
ing operations etc. This welder is dimensioned to supply a I
max nominal current in complete safety for a period of work of
40% of the total usage time. The regulations in force establish
the total usage time to be 10 minutes. The work cycle is con-
sidered to be 40% of this period of time. If the permitted work
cycle time is exceeded, an overheat cut-off occurs to protect
the components around the welder from dangerous overheat-
ing. Activation of thermal protection is signaled by "t° C" flash-
ing on control panel display (for further information see the
paragraph in the manual for the MX control panel). After sev-

How to lift up the machine

The weld machine has a strong handle all in one with the frame,
used for transporting the machine manually only.
NOTE: These hoisting and transportation devices conform to
European standards. Do not use other hoisting and transpor-
tation systems.

Open the packaging

The system essentially consists of:
• MATRIX 2800 E or E-MG weld unit.
• Welding cables or RTA TIG torch (optional).
• Neck strap CB 2 (optional).
Upon receiving the system:
• Remove the welding generator and all relevant accessories-
components from their packaging.
• Check that the weld machine is in good condition, if not report
any problems immediately to the seller-distributor.
• Make sure all ventilation grilles are open and that no foreign
bodies are blocking the air circulation.

Installation

The installation site for the system must be carefully chosen
in order to ensure its satisfactory and safe use. The user is re-
sponsible for the installation and use of the system in accord-
ance with the producer's instructions contained in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
• Signalling, control and telephone cables.
• Radio and television transmitters and receivers.
• Computers and control and measurement instruments.
• Security and protection instruments.
Persons fitted with pace-makers, hearing aids and similar
equipment must consult their doctor before going near a ma-
chine in operation. The environment in which the equipment
is installed must be suitable for the casing's protection level.
This system is cooled by means of the forced circulation of air,
and must therefore be placed in such a way that the air may
be easily sucked in and expelled through the apertures made
in the frame.
The welding unit is characterised by the following levels:
• Protection level IP 23 S indicates that the equipment can be
used both indoors and outdoors.
• Use class "S" means that the equipment can be used in con-
ditions subject to heightened electrical shock.

Connection to the electrical supply

Connection of the machine to the user line (electrical cur-
rent) must be performed by qualified personnel.
Before connecting the welding machine to the mains pow-
er supply, make sure that rated voltage and frequency cor-
respond to those provided by the mains power supply and
that the welding machine's power switch is turned to "O".
Use the welder's own plug to connect it up to the main pow-
er supply. Proceed as follows if you have to replace the plug:
• 3 conducting wires are needed for connecting the machine
to the supply.
• The fourth, which is YELLOW GREEN in colour is used for
making the "GROUND" connection.
