All welders should take the following precautions in order to minimise exposure to the electromagnetic elds (EMF)

generated by the welding circuit::

– position the welding cables together – if possible, attach them;

– keep your head and torso as far as possible from the welding circuit;

– never wrap the cables around your body;

– never position your body between the welding cables. Hold both welding cables on the same side of your body;

– connect the earth clamp as close as possible to the area being welded;

– do not work too close to, do not lean and do not sit on the welding machine

– do not weld when you’re carrying the welding machine or its wire feeder.

People wearing pacemakers are advised to consult their doctor before using this device.

Exposure to electromagnetic elds while welding may have other health effects which are not yet

known.

RECOMMENDATIONS TO ASSESS THE WELDING AREA AND WELDING INSTALLATION

Overview

The user is responsible for installing and using the arc welding equipment in accordance with the manufacturer’s

instructions. If electromagnetic disturbances are detected, it is be the responsibility of the user of the arc welding

equipment to resolve the situation with the manufacturer’s technical assistance. In some cases this remedial action

may be as simple as earthing the welding circuit (see note). In other cases, it may be necessary to construct an

electromagnetic shield around the welding power source and around the entire piece by tting input lters. In all cases,

electromagnetic interferences must be reduced until they are no longer bothersome.

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, in particular, it should consider the following:

a. Other cables, control cables, telephone cables: above, below and besides the device;

b. Radio/TV transmitters and receptors,

c. Computers and other control equipments,

d. Critical safety equipments such as industrial machines’ emergency controls.

e. The health and safety of the people who are close to the machine, e.g. people who wear a pacemaker, a hearing aid,

etc ...

f. Equipment used to calibrate and measure,

g. The immunity of the other equipments installed in the welding area or near the welding machine. The user will have

to make sure that the devices in the same room are compatible with each other. This may require additional precautions.

h. The time of day during which the unit must operate;

The surface of the area to be considered around the device depends on the the building’s structure and other activities

that take place there. The area taken in consideration can be larger than the limits determined by the companies.

Welding area assessment

Besides the welding area, the assessment of the arc welding systems installation itself can be used to identify and

resolve cases of disturbances. The assessment of emissions must include in-situ measurements as specied in Article 10

of CISPR 11: 2009. In situ measurements can also be used to conrm 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. If interferences occur, it may be necessary to take additional preventive measures

such as the ltering of the power supply 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 machine to ensure good electrical contact between the metal conduct and

the casing of the welding machine.

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 modied

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

groud.
