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
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.
C. Methods of Reducing Electromagnetic
Emissions
1. Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations. If interference
occurs, it may be necessary to take additional precautions such as filtering of the mains supply. Consideration should be given
to shielding the supply cable of permanently installed welding equipment in metallic conduit or equivalent. Shielding should
be electrically continuous throughout its length. The shielding should be connected to the Welding Power Source so that good
electrical contact is maintained between the conduit and the Welding Power Source enclosure.
2. Maintenance of Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations. All access and
service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding
equipment should not be modified in any way except for those changes and adjustments covered in the manufacturer’s
instructions. In particular, the spark gaps of arc striking and stabilizing devices should be adjusted and maintained according
to the manufacturer’s recommendation
3. Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at or close to the
floor level.
