INSTALLATION, OPERATION AND SETUP

the electrode at the same time. The operator should be insulated from all such bonded metallic

components.

5. Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of it’s

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 users, or damage to other electrical equipment. Where

necessary, the connection of the workpiece to earth should be made by direct connection to the

workpiece, 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.
