3.04 ELECTROMAGNETIC COMPATIBILITY
WARNING
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 troublesome.
NOTE
The welding circuit may or may nor be earthed for safety reasons. Changing the earthing
arrangements should only be authorised by a person who is competent to assess whether the
changes will increase the risk of injury, e.g. by allowing parallel welding current return paths which
may damage the earth circuits of other equipment. Further guidance is given in IEC 60974-13 Arc
Welding Equipment - Installation and use (under preparation).
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, signalling 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 pacemakers 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.
