5. Earthing/grounding of the Work Piece
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.
