2. SAFETY
This machine, in its design, component specification and production, is in accordance
with the regulations in force [EU directives, European (EN) and international (IEC)
standards. The European Directives "Electromagnetic Compatibility", "Low Voltage" and
"RoHS" as well as the IEC / EN 60974-1 and IEC / EN 60974-10 standards are applicable.
Electric shocks can be fatal.
-This machine must be connected to earthed sockets. Do not touch the live parts
of the machine.
-Before any intervention, disconnect the machine from the mains. Only qualified
personnel should work on these machines.
-Always check the condition of the power cable.
It is essential to protect the eyes from the radiation of the electric arc. Use a welding
shield with a suitable protective filter.
Use localised extraction. Smoke and fumes can damage the lungs and cause poisoning.
Risk of fire or explosion.
-Remove all explosive or flammable products from the welding area;
-Check that there is a sufficient number of fire extinguishers in the vicinity of the
welding area;
-Check that the sparks projected cannot cause a fire, remembering that these
sparks can reignite several hours after the end of welding.
Hot parts can cause burns. Workpiece, spatter and droplets are hot. Wear gloves,
aprons, safety shoes and other personal safety equipment.
Electromagnetic fields generated by welding machines may cause interference to other
devices. They may affect cardiac pacemakers.
Gas bottles can explode (MIG or TIG welding). It is essential to comply with all safety
regulations regarding gases.
Electromagnetic compatibility
If electromagnetic disturbances occur, it is the responsibility of the user to remedy the problem with
the manufacturer's technical support. In some cases, corrective action may be reduced to simply
grounding the welding circuit (see note below). In the opposite case, it may be necessary to build an
electromagnetic shield around the source and add input filters to this measure. In any case,
electromagnetic disturbances should be reduced until they do not disturb nearby welding equipment
or persons. The following situations should be taken into account:
-Power cables, control cables, display and telephone cables close to the welding equipment.
-Radio and television transmitters and receivers.

7
MICROTIG DC 162 / 202 PULSE
ES
PT
- Computers and other control equipment.
- Safety-critical equipment, in particular the monitoring of industrial equipment.
-Health of the people around, in particular those wearing cardiac stimulants and hearing aids.
-Equipment used for calibration.
-Immunity of other surrounding equipment. The user must ensure that these materials are
compatible. This may require additional protective measures.
-Time at which welding materials and other equipment operate.
2.1. Methods to reduce emissions
Power supply
The welding equipment must be connected to the mains according to the manufacturer's instructions.
Should interference occur, it may be necessary to take additional precautions such as filtering the
power supply. It is necessary to take into account the shielding of the power cables of welding
equipment permanently installed in metallic conduits or equivalent. Shielding must be carried out in
compliance with electrical continuity. The welding source must be connected in such a way that there
is always a good electrical contact.
Welding Cables
Welding cables should be as short as possible and in good serviceable condition (no splices), on or near
the ground.
Equipotential bonding
The links between all metallic components in and adjacent to the welding installation must be taken
into account. However, metallic components connected to the part being worked on increase the risk
of electric shock if the user touches the metallic components and the electrode at the same time. The
user must be isolated from all connected metallic components.
Earth connection
When the part to be welded is not earthed for electrical safety reasons or because of its size or position
(e.g. ship hull, steel mill), a connection of the part to earth may reduce emissions in some cases. Care
must however be taken to ensure that this connection does not increase the risk of injury to the user or
damage other electrical equipment. When necessary, the grounding of the part must be made by a
direct connection, but in some countries where this is not authorised, the connection must be made by
a capacitance resistor and according to national regulations.
Shielding and protection
Selective shielding and protection of other cables and materials in the surrounding area can limit
interference problems. Shielding of the entire welding installation may be considered for special
applications.

2.2. Electric safety
Connection to the power supply
Before connecting your appliance, check that:
-The electrical meter, the overcurrent protection device and the electrical installation are
compatible with the maximum power and supply voltage of your welding equipment (indicated
on the nameplate).
-The single-phase or three-phase earthed connection must be made on a basis appropriate to
the maximum current of the welding equipment.
-If the cable is connected to a fixed post, the earth, if provided, shall never be cut off by the
electric shock protection device.
-The welding power source switch, if provided, shall indicate "OFF".
Job position
The application of arc welding implies strict compliance with the safety conditions regarding electric
current (decree of 14.12.1988). It is necessary to ensure that no metallic part accessible to welders can
come into direct or indirect contact with a conductor of the power supply network. If there is any doubt
about this serious risk, a conductor of this metallic part shall be connected to earth with an electrical
cross-section at least equivalent to that of the largest phase conductor.
It is also necessary to ensure that a conductor connects any metallic part which the welder could
touch on an uninsulated part of the body (head, ungloved hand, bare arm, etc.) to earth of an electrical
cross-section at least equivalent to that of the largest power cable of the earth clamp or welding
torch. If several metal grounds are used, they shall be connected at one point, earthed under the same
conditions.
Welding and arc cutting shall be prohibited, except in very special cases in which stringent measures
shall be applied, in narrow conductive enclosures in which welding apparatus must be left outside.
Very serious safety measures shall be compulsory a priori for welding in poorly ventilated or damp
enclosures.
Risk of fire or explosion
Welding may involve risks of fire or explosion. Some precautions must be observed:
-Remove all explosive or flammable products from the welding area;
-Check that there is a sufficient number of fire extinguishers in the vicinity of the welding area;
-Check that the sparks projected cannot cause a fire, remembering that these sparks can
reignite several hours after the end of welding.
2.3. Individual protection
Risks of external injury
Electric arcs produce very bright infrared light and ultraviolet rays. These rays will damage your eyes
and burn your skin if not properly protected.
-The welder must be equipped and protected according to the difficulties of the work.
-They must be covered in such a way that no part of the welder's body can come into contact with
metal parts of the welding equipment, and also those which could come into contact with the
voltage of the mains supply.

9
MICROTIG DC 162 / 202 PULSE
ES
PT
-The welder must always wear individual insulating protection.
The welder's protection systems shall be as follows: gloves, aprons, safety shoes, etc. These offer
the additional advantage of protecting against burns caused by spatter and slag. Users must ensure
that these protective systems are in good condition and renew them if they deteriorate.
-It is essential to protect the eyes against arc flash (glare from the arc in visible light and infrared
and ultraviolet radiation).
-Hair and face against projections.
The welding shield, with or without helmet, is always provided with a protective filter specified in
relation to the current intensity of the welding arc (NS Standards S 77-104/A 88-221/A 88-222). The
coloured filter can be protected from shocks and projections by transparent glass.
The screen used must be used with a protective filter. It must be replaced by the same references
(opacity level number). See the table below for the level of protection recommended for the welding
method.
Persons in the vicinity of the welder must be protected by the interposition of UV protection screens
and, if necessary, by a welding screen provided with a suitable protective filter (NF S 77-104- por. A 1.5).

Risks of internal injuries
Safety against fumes and vapours, noxious and toxic gases
-Arc welding operations with electrodes must be carried out in suitably ventilated areas.
-Welding fumes emitted in workshops must be collected as they are produced, as close as
possible to their production and discharged directly to the outside. Fume extractors must be
installed for this purpose.
-Chlorinated solvents and their vapours, even at a distance, if affected by arc radiation, are
transformed into toxic gases.

3. TIG WELDING (Tungsten Inert Gas)
It is an electric arc welding process under gaseous protection, using a torch with an infusible tungsten
electrode and can be performed with or without filler metal, in an inert gas atmosphere such as argon
and its mixtures.
The melting temperature of the tungsten electrode is 3400ºC higher than the metals to be welded so it
does not melt or release contaminating welding atoms.
Through this process you can weld with a very stable electric arc without spatter and slag which
guarantees a high mechanical strength of the welded joints.
TIG welding replaces oxyacetylene welding with advantages especially in the welding of mild steels and
stainless steel in direct current (DC) or aluminium and its alloys in alternating current (AC).
In specific cases, it can also be advantageous in connection with mainly MMA welding (fusible
electrode) or MIG welding that does not require the addition of metal or thin sheets in which the wires
are not visible.

Shielding gases: Gases used in TIG welding contribute to:
-To involve the electric arc in an ionisable atmosphere.
-Avoid contamination of the weld by oxygen in the atmosphere.
-To cool the electrode.
Argon(Ar)
The most common gas used with a purity grade of 99.9%.
Helium (He)
Pure helium is used for copper welding mixed with argon in percentages varying between 10% and
75%.
Hydrogen (H)
It is an inert gas at room temperature and is used especially in copper soldering. It is not
recommended for soldering in enclosed spaces because it combines with oxygen to create an
unbreathable atmosphere.
4. MMA WELDING (coated electrode)
To establish a welding arc, a potential difference is induced between the electrode and the workpiece.
potential difference between the electrode and the workpiece.
The air between them is ionised and becomes conductive, so that the circuit is closed and creates the
electric arc. The heat of the arc partially melts the base material which is deposited creating a weld
pool. Arc welding is still very common due to the low cost of the equipment and consumables used in
this process.
An electric arc is formed between the electrode and the metal to be welded by means of an electric
current. The temperatures reached cause it to melt and deposit in the welded joint. Metal core
electrodes made of steel or other alloys are coated with a fluxing material which creates a protective
atmosphere that prevents oxidation of the molten metal and facilitates the welding operation.
In DC power sources (rectifiers) the polarity of the electric current affects the mode of metal transfer.
Typically, the electrode is connected to the positive (+) pole, although in welding very thin materials, it
may be connected to the negative (-) pole.
The most favourable welding position is horizontal, while welding can be carried out in any position.

7. INSTALLATION
7.1. Connection to the power supply
The equipment must be supplied with 230V - 50 Hz/60 Hz single-phase + earth.
The power supply must be fitted with a device (fuse or circuit breaker) corresponding to the I1eff value
indicated on the nameplate of the equipment.
The installation of a differential protection device is not compulsory except for the safety of the users.
7.2. Connection
For the protection of the users, the equipment must be correctly connected to the earthing installation
(INTERNATIONAL SAFETY RULES).
It is essential to establish a good earth connection via the green/yellow conductor of the power cable in
order to avoid discharges due to accidental contact with live parts in contact with earth. If the earth
connection is not made, there is a risk of electric shock to the machine casing.
Avoid placing the device in rooms with high dust concentration, humidity or excessive ambient
temperatures.
