standard: EN 50 199 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment. It
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be
received by other equipment, electrical interference may result. Electrical emissions may affect many kinds of
telephone systems, computers, etc. Be aware that interference may result and extra precautions may be required
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
electromagnetic disturbances must be reduced to the point where they are no longer troublesome.

surrounding area. The following shall be taken into account:
welding equipment;
b) radio and television transmitters and receivers;
d) safety critical equipment, e.g., guarding of industrial equipment;
e) the health of the people around, e.g., the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement;

when a welding power source is used in a domestic establishment.
Installation and Use
The user is responsible for installing and using the welding equipment according to the manufacturer s instructions.
be as simple as earthing (grounding) the welding circuit, see Note. In other cases it could involve constructing an
electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.
Changing the earthing arrangements should only be authorized by a person who is competent to
current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the
