RECOMMENDATIONS FOR WELDING AREA ASSESSMENT AND WELDING
Miscellaneous
The user is responsible for the correct installation and usage of the welding material based on the instructions supplied by the manufacturer. If
electromagnetic disturbances are detected, it is the user's responsibility to resolve the situation with the manufacturer's technical assistance. In some
cases, this corrective action may be as simple as earthing the welding circuit. In other cases, it may be necessary to construct an electromagnetic
shield around the welding power source and around the entire piece by fitting input filters. In all cases, electromagnetic interferences must be reduced
until they are no longer inconvenient.
Welding area assessment
Before installing the machine, the user must evaluate the possible electromagnetic problems that may arise in the area where the installation is
planned. The following must be taken into account:
a) the presence (above, below and next to the arc welding machine) of other power cables, remote cables and telephone cables;
b) television transmitters and receivers;
c) computers and other hardware;
d) critical safety equipment such as industrial machine protections;
e) the health and safety of people in the area especially if they are using pacemakers or hearing aids;
f) calibration and measuring equipment;
g) the isolation of other pieces of equipment which are in the same area.
The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This may require extra precautions;
h) the time of day during the welding or other activities have to be performed.
The dimension of the cutting area that has to be considered depends on the size and shape of the building and the type of work undertaken. The area
taken into consideration might go beyond the limits of the installations.
Review of the welding installation
Reviewing the welding installations can be useful to determine and resolve any case of electrical disturbances. The assessment of emissions must
include in situ measurements as specified in Article 10 of CISPR 11. In situ measurements can also be used to confirm the effectiveness of mitigation
measures.
RECOMMENDAED METHODS TO REDUCE ELECTROMAGNETIC EMISSIONS
a. National power grid: The arc welding machine must be connected to the national power grid in accordance with the manufacturer's
recommendation. In case of interferences, it may be necessary to take additional precautions such as the filtering of the power supply network.
Consideration should be given to shielding the power supply cable in a metal conduit or equivalent of permanently installed arc welding equipment. It
is necessary to ensure the electrical continuity of the frame along its entire length. The shielding should be connected to the welding current source
to ensure a good electrical contact between the conduit and the casing of the welding current source.
b. Maintenance of the resistance welding equipment: The resistance welding machine should be subject to a routine maintenance check in line
with the recommendations of the manufacturer. All accesses, service doors and covers should be closed and properly locked when the arc welding
equipment is on. The arc welding equipment must not be modified in any way, except for the changes and settings covered in the instructions.
c. Welding cables: Cables must be as short as possible, close to each other and close to the ground, if not on the ground.
d. Equipotential bonding: consideration should be given to bond all metal objects in the surrounding area. However, metal objects connected to
the workpiece increase the risk of electric shock if the operator touches both these metal elements and the electrode. It is necessary to insulate the
operator from such metal objects.
e. Earthing of the welded part: When the part is not earthed - due to electrical safety reasons or because of its size or location (which is the case
with ship hulls or metallic building structures), the earthing of the part can, in some cases but not systematically, reduce emissions It is preferable to
avoid the earthing of parts that could increase the risk of injury to the users or damage other electrical equipment. If necessary, it is appropriate that
the earthing of the part is done directly, but the safety rules in some countries may not allow such a direct connection and it is appropriate that the
connection is made using a capacitor selected according to national regulations.
f. Protection and shielding: The selective protection and shielding of other cables and devices in the area can reduce perturbation issues. The
protection of the entire welding area can be considered for specific situations.
TRANSPORT AND TRANSIT OF THE WELDING MACHINE
The top of the machine is equipped with handles for movement by hand. Be careful not to underestimate the weight of the
machine. The handles cannot be used to lift the product.
Do not use the cables or torch to move the machine. Do not place/carry the unit over people or objects.

EQUIPMENT INSTALLATION

• Put the machine on the floor (maximum incline of 10°).
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP20, which means :
- Protection against access to dangerous parts from solid bodies of a diameter ≥12.5mm and,
- Protection against water projections.
Power cables, extension leads and welding cables must be fully uncoiled to prevent overheating.
The manufacturer does not accept any liability in relation to damages caused to objects or harm caused to persons as the result
of incorrect and/or dangerous use of the machine.
