connected to the Welding Power Source so that good electrical contact is
maintained between the conduit and the Welding Power Source enclosure.
2. Maintenance of Welding Equipment
The welding equipment should be routinely maintained according to the
manufacturer's recommendations. All access and service doors and covers
should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except
for those changes and adjustments covered in the manufacturer's instruction
In particular, the spark gaps of arc striking an

3. Welding Cables
The welding cables should be kept as short as possible and should be
positioned close toge
4. Equipotential Bonding
Bonding of all metallic components in the weldin
should be considered. However, metallic compon

5. Earthing 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,
steelwork, a connection bonding the work piece to earth may reduce
in some, but not all instances. Care should be taken to prevent the ea
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 connectio
countries where direct connection is not permitted, the bonding should be
achieved by suitable capacitance, selected according to national regulations.
