Assessing the welding area
Before installing arc welding equipment, the user should assess the potential electromagnetic problems in the surroun-
ding area. The following should be taken into account:
a) the presence above, below and next to the arc welding equipment of other power cables, control cables, signal or
telephone cables;
b) radio and television receivers and transmitters;
c) computers and other control equipment,
d) critical safety equipment, for example, industrial equipment protection;
e) the well-being of nearby persons, for example, those using of pacemakers or hearing aids,
f) the equipment used for calibrating or measuring;
g) the protection of other surrounding equipment.
The operator has to ensure that the devices and equipment used in the same area are compatible with each other. This
may require further protective measures;
h) the time of day when welding or other operations are to be carried out.
The size of the surrounding area to be taken into account will depend on the building's structure and the other activities
taking place there. The surrounding area may extend beyond the boundaries of the premises.
Assessment of the welding equipment
In addition to assessing the area, the arc welding equipment's assessment can be used to identify and resolve cases of
interference. 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. The mains power grid: Arc welding equipment should be connected to the mains power grid according to the
manufacturer's recommendations. If interference occurs, it may be necessary to take additional precautionary measures
such as filtering the mains power supply. Consider protecting the power cables of permanently installed arc welding
equipment within a metal pipe or a similar casing. The power cable should be protected along its entire length. The
shield should be connected to the welding power source to ensure that there is good electrical contact between the
conduit and the welding power source enclosure.
b. The maintenance of arc welding equipment: Arc welding equipment should be subject to routine maintenance
as recommended by the manufacturer. All access points, covers and service openings should be closed and properly
locked when the arc welding equipment is in use. The arc welding equipment should not be modified in any way, except
for those changes and adjustments mentioned in the manufacturer's instructions. It is advisable, in general, the arc
ignition and stabilization parts should be adjusted and maintained according to the manufacturer's recommendations.
c. Welding cables: Cables should be as short as possible, placed close together either near or on the ground.
d. Equipotential bonding: Consideration should be given to linking all metal objects in the surrounding area. Howe-
ver, metal objects connected to the workpiece increase the risk of an electric shock to the operator if they touch both
the metal objects and the gun shaft It is necessary to insulate the operator from such metal objects.
e. Earthing the workpiece: In cases where the part to be welded is unearthed for electrical safety reasons or due
to its size and location, which is the case, for example, the hull of a ship or steel frameworks of buildings, an earthed
connection can in some cases but not always, reduce emissions. Care should be taken to avoid the earthing of parts
which could increase the risk of injury to users or damage to other electrical equipment. If necessary, the connection of
the workpiece to earth should be made directly, but in some countries; rules may not allow such a direct connection, he
connection should be made with a suitable capacitor chosen according to national regulations.
f. Protection and shielding: The selective protection and encasing of other cables and equipment in the surrounding
area may limit interference problems. The safeguarding of the entire welding area may be considered for special appli-
cations.
THE TRANSPORTING AND MOVING OF THE MACHINE'S POWER SOURCE
The machine is equipped with a handle to easy transportation. Be careful not to underestimate its
weight. The handle cannot be used to hang or attach the machine on something else.
Do not use the cables or gun to move the welding power source. It should be moved in an upright
position.
Do not carry or transport the power source overhead of people or objects.
Never lift the machine while there is a gas cylinder on the support shelf. Their transportation require-
ments are different.
