Cutting 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.
In particular, it should consider the following:
a) the presence of other power cables (power supply cables, telephone cables, command cable, etc...) above, below and on the sides of the arc
welding machine.
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 the equipment from other machinery.
The user will have to make sure that the devices and equipments that are in the same room are compatible with each other. This may require extra
precautions;
h) make sure of the exact hour when the welding and/or other operations will take place.
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.
Cutting area assessment
Besides the welding area, the assessment of the cutting 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: 2009. 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 cutting 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 filtering 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 cutting current's source to ensure good electrical contact between the conduct and the casing
of the welding current source..
b. Maintenance of the cutting equipment: The cutting 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 cutting equipment is on. The
cutting 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. Cutting 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 cutted 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 specific situations.
TRANSPORT AND TRANSIT OF THE CUTTING MACHINE
The machine is fitted 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.
A clear path is available when moving the item.
EQUIPMENT INSTALLATION
• Put the machine on the floor (maximum incline of 10°.)
• Ensure the work area has sufficient ventillation for cutting, 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 vertical rainfall.
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 .
