The surface of the area to be considered around the device depends on the the building’s structure and other activities
that take place there. The area taken in consideration can be larger than the limits determined by the companies.
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 specied in Article 10 of
CISPR 11: 2009. In situ measurements can also be used to conrm 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. If interferences occur, it may be necessary to take additional preventive measures
such as the ltering of the power suplly network. Consideration should be given to shielding the power supply cable in a
metal conduit. It is necessary to ensure the shielding’s electrical continuity along the cable’s 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 be submitted to a routine
maintenance check according to the manufacturer’s recommendations. 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 modied
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. Electrical bonding : consideration shoud be given to bonding all metal objects in the surrounding area. However,
metal objects connected to the workpiece increase the riskof 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 plating : The selective protection and plating of other cables and devices in the area can reduce
perturbation issues. The protection of the entire welding area can be considered for specic situations.
TRANSPORT AND TRANSIT OF THE WELDING MACHINE
The machine is tted with handle(s) to facilitate transportation. Be careful not to underestimate the
machine’s weight. The handle(s) cannot be used for slinging.
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.
EQUIPMENT INSTALLATION
• Put the machine on the oor (maximum incline of 10°.)
• Ensure the work area has sufcient ventillation for welding, and that there is easy access to the control panel.
• The machine must not be used in an area with conductive metal dusts.
• 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.
The power cables, extensions and welding cables must be fully uncoiled to prevent overheating
The manufacturer does not incur any responsability regarding damages to both objects and persons
that result from an incorrect and/or dangerous use of the machine.
