g. The immunity of other equipment in which the equipment is to be used. The user must ensure that other
equipment used in the same place is compatible. This may require additional protection measures;
h. The time of day when welding or other activities are carried out
i. The size of the area to be considered will depend on the structure of the building and any other
processes in the area. The surrounding area may extend beyond the boundaries of the buildings.
Recommendation to reduce electro-magnetic emission
Mains power supply: the equipment must be connected to the power mains as specified in the
a.
Manufacturer's instructions. If interference occurs, additional precautions such as filtering of the mains
supply may be required. The supply cable in the welding machine's permanent installations may have to
be screened in metal conduits or similar. The screening should be electrically continuous for the entire
length of the cable. It should also be connected to the welding machine with a good electrical contact
between the metal conduit and the casing.
Welding cables: The welding cables should be kept as short as possible and should be positioned close
b.
together, running at or close to the floor level.
Protection and reinforcement: Selective screening and shielding of other cables and equipment in the
c.
surrounding area may alleviate problems of interference. Screening of the entire welding area may be
considered for special applications
Connect the earth directly to the metal piece to be welded: Where necessary, the connection of
d.
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 suitable capacitance,
selected according to national regulations.
