9.4.
Assessment of area.
Before installing the equipment the user shall make an assessment of potential electromechanical problems in the
surrounding area. 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.
The following shall be taken into account :
a) Other supply cables, control cables, signalling and telephone cables, above, below and adjacent to the welding equipment.
b) Radio and television transmitters and receivers.
c) Computer and other control equipment.
d) Safety critical equipment, e.g. security monitoring of industrial equipment.
e) The health of people in the vicinity, e.g. persons fitted with a pacemaker or hearing aid.
f) Equipment used for calibration or measurement.
g) 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 protective measures.
h) The time of day that welding and other activities are to be carried out.
9.5.
Mains supply.
The equipment should be connected to the mains supply according to these instructions. If interference occurs, it may be
necessary to take additional precautions such as filtering of the mains supply. Consideration should also be given to shielding the supply
cable of permanently installed equipment, in metallic conduit or equivalent. This shielding should be connected to the power source so
that good electrical contact is maintained between the conduit and the welding power source enclosure.
9.6.
Maintenance of the welding equipment.
The equipment should be routinely maintained according to these instructions. All access
and service 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 these instructions. In particular, the spark gaps of any arc
striking and stabilising devices should be adjusted and maintained according to the instructions.
9.7.
Welding cables.
The welding/cutting cables should be kept as short as possible and should be positioned close together, running at or
close to the floor level.
9.8.
Equipotential bonding.
Bonding of all metallic components in the welding installation and adjacent to it should be considered.
However, metallic components bonded to the workpiece will increase the risk that the operator could receive a shock by touching these
metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.
9.9.
Earthing of the workpiece.
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size
and position, e.g. ships hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not
all instances. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to others or damage to other
electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece,
but in some countries where direct connection is not permitted, the bonding should be achieved by a suitable capacitance, selected
according to national regulations.
9.10.
Screening and shielding.
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems
of interference. Screening of the entire welding installation may be considered for special applications.
