3. Methods of reducing emissions
1) Public supply system
Arc welding equipment should be connected to the public supply system according to the
manufacturer’s recommendations. If interference occurs, it may be necessary to take
additional precautions such as filtering of the public supply system. Consideration should
be given to shielding the supply cable of permanently installed arc welding equipment, in
metallic conduit or equivalent. Shielding should be electrically continuous 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 the arc welding equipment
The arc 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 arc welding equipment is in operation. The arc
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 recommendations.
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.
4) Equipotent bonding
Bonding of all metallic components in the welding installation and adjacent to it should be
considered. However, metallic components bonded to the word piece will increase the risk
that the operator could receive an electric shock by touching these metallic components
and the electrode at the same time. The operator should be insulated from all such bonded
metallic components.
