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 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 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 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. 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 specific situations.
TRANSPORTATION OF THE MACHINE
It is preferable to drain the cooling unit before transport.
Do not place/carry the unit over people or objects.
INSTALLATION
• Put the machine on the floor (maximum incline of 10°.)
• Ensure the work area has sufficient ventillation for welding, and that there is easy access to the control panel.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine must not be used in an area with conductive metal dusts.
• The MULTICOOL 500 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 MULTICOOL 1300 machine protection level is IP23S, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60% towards the vertical.
These devices can be used outside in accordance with the IP23S protection index.
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.
The power cables, extensions and welding cables must be fully uncoiled to prevent overheating.
MAINTENANCE / RECOMMENDATIONS
• Remove the casing 2 or 3 times a year to remove any excess dust. Take this opportunity to have the electrical connections checked by a qualified
person, with an insulated tool.
• Regularly check the condition of the power supply cable. If the power cable is damaged, it must be replaced by the manufacturer, its after sales
service or an equally qualified person.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
The cooling liquid must be changed every 12 month in order to avoid sediments which could block the torch cooling circuit.
Any leak or residual fluid, after use, must be handled within the appropriate purification factory. If possible, recyclke the product.
It is prohibited to empty the product in a river, a sceptic tank or a draining system. The diluted fluid must not be emptied in the
sewers, unless euthorised by the local regulations.
