4. Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered. However, metallic
components 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 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.
3.05 Setup for Welding
NOTE!
Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead
directly to work piece and electrode lead is used to hold electrode. Wide safety margins provided by the de-
sign ensure that the Welding Power Source will withstand short-term overload without adverse effects. The
welding current range values should be used as a guide only. Current delivered to the arc is dependent on
the welding arc voltage, and as welding arc voltage varies between different classes of electrodes, welding
current at any one setting would vary according to the type of electrode in use. The operator should use the
welding current range values as a guide then fine tune the welding current to suit the application.
!
WARNING
Before connecting the work clamp to the work and inserting the electrode in the electrode holder make
sure the Primary power supply is switched off.
!
CAUTION
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Welding
Power Source.
