Methods of reducing emissions
Public supply system
Arc welding equipment should be connected to the public supply system
according to this manual 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 throughout 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. Maintenance of the arc welding equipment. The arc welding
equipment should be routinely maintained according to this manual
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 this manaul. In particular, the spark gaps of arc striking
and stabilising devices should be adjusted and maintained according to our
recommendations.
