WARNING!
The welding circuit may or may not be earthed for safety reasons. Changing the
earthing arrangements should only be authorized by a person who is competent to
assess whether the changes will increase the risk of injury, for example: by allowing
parallel welding current return paths which may damage the earth circuits of other
equipment.
WARNING!
Equipotential bonding:
Bonding of all metallic components in the welding installation and adjacent to it
might be considered. However, metallic components bonded to the work piece will
increase the risk that the operator could receive a shock by touching the metallic
components and the electrode at the same time. The operator should be insulated
from all such bonded metallic components.
WARNING!
Earthing/grounding of the work place:
Care should be taken to prevent the earthing of the work piece increasing the risk of
injury to users, or damage to other electrical equipment. Changing the earthing
arrangements should only be authorized by a person who is competent to assess
whether the changes will increase the risk of injury.
WARNING!
The importance of correct installation of high frequency welding equipment cannot
be overemphasized. Interference due to high frequency initiated or stabilized arc is
almost invariably traced to improper installation. A duly authorized person such as a
properly licensed electrician should perform the installation to avoid injury, death, or
any equipment damage.
4.2.1
User’s 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. This remedial action may be as simple as earthing the
welding circuit. 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.
4.2.2
Assessment of area
Before installing welding equipment, the user shall assess potential electromagnetic
problems in the surrounding area. The following shall be considered:
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.
