9.9.

Earthing of the workpiece. 

Where the workpiece 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 workpiece to earth may reduce emissions in some, but not 

all instances. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to others or damage to other

electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece,

but in some countries where direct connection is not permitted, the bonding should be achieved by a suitable capacitance, selected 

according to national regulations.

9.10.

Screening and shielding.

Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems

of interference. Screening of the entire welding/cutting installation may be considered for special applications.
