where the installation is planned. The following elements should 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 the people in the area such as people with pacemakers or hearing aids;
f) calibration and measuring equipment;
g) the isolation of other pieces of equipment which are in the same area.
The user has to ensure that the devices and pieces of 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 surface of the area to be considered around the device depends on the building's structure and other activities that
take place there. The area taken into consideration can be larger than the limits of the installations.
Welding area assessment
Besides the welding area, the assessment of the arc welding systems intallation itself can be used to identify and resolve
cases of 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.
RECOMMENDATION ON METHODS OF ELECTROMAGNETIC EMISSIONS REDUCTION
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 shielding along its entire length. The shielding should be connected to the welding current's source to ensure
good electrical contact between the conduct and the casing of the welding current source.
b. Maintenance of the arc welding equipment: The arc welding machine should be subject to a routine maintenance
check according to 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 outlined in the manufacturer's instructions. The spark gap of the arc start and arc
stabilization devices must be adjusted and maintained according to the manufacturer's recommendations.
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 bonding 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
and its 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 in some countries that do not allow such a direct connection, it is appropriate that the connection
is made with 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 machine is equipped with a top strap for easy transportation. Be careful not to underestimate the
weight of the machine. The strap is not design to be use to hang the machine to something else.
Do not use the cables or torch to move the machine. The welding equipment must be moved in an
upright position.
Do not place/carry the unit over people or objects.
INSTALLATION
• Put the machine on the floor (maximum incline of 10°).
• Provide an adequate area to ventilate the machine and access the controls.
• Do not use in an area with conductive metal dust.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP21, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against vertically falling drops.
