RECOMMENDATIONS FOR WELDING AREA ASSESSMENT AND WELDING
Overview
The user is responsible for the installation and use of the arc cutting equipment according to the manufacturer's instructions. If electromagnetic
disturbances are detected, the user is responsible for resolving the situation with the manufacturer's technical assistance. In certain cases, this
corrective action may be as simple as earthing the cutting circuit. In other cases, it may be necessary to construct an electromagnetic shield around
the cutting 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.
Cutting area assessment
Before installing the machine, the operator must evaluate the possible electromagnetic problems that may arise in the area where the installation is
planned. The following elements should be considered:
a) the presence (above below and next to the arc cutting 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 operator has to ensure that the devices and 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 dimension of the cutting area that has to be considered depends on the size and shape of the building and the type of work undertaken. The area
taken into consideration might go beyond the limits of the installations.
Cutting area assessment
Besides the welding area, the assessment of the arc cutting system installation itself can be used to identify and resolve cases of distrubances 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.
RECOMMENDATIONS METHODS TO REDUCE ELECTROMAGNETIC EMISSIONS
a. National power grid: the arc cutting 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 shield the power supply cable in a metal frame or equivalent from a permanent cutting installation. It is necessary to ensure the electrical
continuity of the frame along its entire length. The from should be connected to the cutting machine to ensure good electrical contact between the
conduct and the casing of the cutting machine.
b. Maintenance of the arc cutting equipment: the arc cutting 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 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 starts and arc stabilization devices must be adjusted and maintained according to 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. 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 the metal parts and the electrode. It is necessary to insulate the operator
from such metal objects.
e. Earthing of the metal part to be cut : When the part is not earthed - due to electrical safety reasons or because of its size and its location (e.g.
ship hulls or metallic building structures), the earthing of the part can, in some cases but 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 direct connection, it is appropriate for the connection to be 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 equipped with a handle for easy transportation. Be careful not to underestimate the weight of the machine. The
handle cannot be used to hang or attach the machine on something else.
Do not use the cable 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.

EQUIPMENT INSTALLATION

• Put the machine on the floor (maximum incline of 10°)
• 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 must be placed in a sheltered area away from rain or direct sunlight.
• The machine protection level is IP23, which means:
- Protection against access to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60% towards the vertical.
The equipment can be used outside in accordance with the IP23 protection certification.
Power cables, extension leads and welding cables must be fully uncoiled to prevent overheating.
