3.4 Electromagnetic Compatibility

Extra precautions for Electromagnetic Compatibility may be required when this
Welding Power Source is used in a domestic situation.
A. Installation and Use - Users Responsibility
The user is responsible for installing and using the welding equipment according
to the manufacturer's instructions. If electromagnetic disturbances are detected
then it shall be the responsibility of the user of the welding equipment to resolve
the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing the welding circuit, see NOTE
below. In other cases it could involve constructing an electromagnetic screen
enclosing the Welding Power Source and the work, complete with associated
input filters. In all cases, electromagnetic disturbances shall be reduced to the
point where they are no longer Trouble-some.
B. Assessment of Area
Before installing welding equipment, the user shall make an assessment of
potential electromagnetic problems in the surrounding area. The following shall
be taken into account.
1. Other supply cables, control cables, signaling and telephone cables; above,
below and adjacent to the welding equipment.
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial equipment.
5. The health of people around, e.g. the use of pace-makers and hearing aids.
6. Equipment used for calibration and measurement.
7. The time of day that welding or other activities are to be carried out.
8. The immunity of other equipment in the environment: the user shall ensure
that other equipment being used in the environment is compatible: this may
require additional protection measures.
The size of the surrounding area to be considered will depend on the structure of
the building and other activities that are taking place. The surrounding area may
extend beyond the boundaries of the premises.
