INSTALLATION, OPERATION AND SETUP 3-4 Manual 0-5425
The welding cables should be kept as short as possible and should be positioned close together but never coiled and running at
or close to the floor level.
4. Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered. However, metallic compo-
nents bonded to the work piece will increase the risk that the operator could receive a shock by touching the metallic components
and the electrode at the same time. The operator should be insulated from all such bonded metallic components.
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.
