Where the work piece is not bonded to earth for electrical safety, nor connected to earth because of its size
and position, e.g. ship’s hull or building steelwork, a connection bonding the work piece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the work piece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection
of the work piece to earth should be made by direct connection to the work piece, but in some countries where
direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according
to national regulations.
6. Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems
of interference. Screening the entire welding installation may be considered for special applications.
