RECOMMENDATIONS FOR EVALUATING THE WELDING AREA AND INSTALLATION
Miscellaneous
The user is responsible for the correct installation and usage of the welding material based on the instructions supplied by the
manufacturer. If electromagnetic disturbances are detected, it is the user's responsibility to resolve the situation with the manufacturer's
technical assistance. In some cases, this corrective action may be as simple as earthing the welding circuit. In other cases, it may be
necessary to construct an electromagnetic shield around the welding power source and around the entire piece by fitting input filters.
In all cases, electromagnetic interferences must be reduced until they are no longer inconvenient.
Welding 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. The following must be taken into account:
a) the presence (above, below and next to the arc welding machine) of other power cables, remote cables and telephone cables;
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 other pieces of equipment which are in the same area.
The user has to ensure that the devices and pieces of equipment used in the same area are compatible with each other. This may
require extra precautions;
h) the time of day during the welding or other activities have to be performed.
The surface of the area to be considered around the device depends on the building's structure and other activities that take place
there. The area taken into consideration can be larger than the limits of the installations.
Review of the welding installation
Reviewing the welding installations can be useful to determine and resolve any case of electrical 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 welding machine must be connected to the national power grid 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 shielding 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.
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 bonding 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 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 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 welding source is fitted with a handle or strap to make it transportable by hand. Be careful not to underestimate the
weight of the machine. The handle or strap are not design to be use to hang the machine to something else.
Do not use the cables or torch to move the machine.
Do not place/carry the unit over people or objects.
