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 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'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 starts and arc
stabilization devices must be adjusted and maintained according to 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 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 workpiece: 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 fitted with handle(s) to facilitate transportation. Be careful not to underestimate the
weight of the machine. 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.
Never lift the machine while there is a gas cylinder on the support shelf. The transport rules applying to
each item are different.
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.
• Provide an adequate area to ventilate the machine and access the controls.
• This equipment must be used and stored in a place protected from dust, acid, gas or any other corrosive substance.
• 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.
• Power, extension and welding cables must be fully uncoil to avoid overheating.
Warning: Increasing the length of the torch or earth return cables beyond the maximum length specified by the
manufacturer will increase the risk of electric shock.
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.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person. A yearly maintenance is recommended.
• Ensure the machine is unplugged from the mains, and then wait 2 minutes before carrying out maintenance
work. Inside, voltages and currents are high and dangerous.
• Remove regularly the casing and any excess of 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 to prevent danger.
• Ensure the vents of the device are not blocked to allow adequate air circulation.
• Do not use this equipment to thaw pipes, to charge batteries, or to start any engine.
