10.5.
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.
10.6.
Maintenance of the 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.
10.7.
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.
10.8.
Equipotential bonding. Bonding of all metallic components in the welding/cutting 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
10.9.
Earthing of the workpiece. It is important that the workpiece is separately bonded to earth in addition to the welder/inverter return
cable. Where the workpiece is not bonded to earth for electrical safety reasons or because of its size and position, e.g. ship's 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..
10.10. 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/cutting installation may be considered for special applications.
