3 Definitions
For the purpose of this technical specification, the following definitions apply:
welding circuit
a circuit that includes all conductive material through which the welding current is intended To
NOTE I — In arc welding, the arc is a part at the welding circuit.
NOTE 2 — In certain arc welding processes, the arc may be established between Iwo electrodes. In such a case. he work piece jan01 necessanly a part olIhe wetding circuit. (IEC 60974-1, 311J
extraneous conductive part
conductive part not forming part of the electrical installation and liable to introduce an electric potential, generally the electric potential of a local earth (1EV 195-06-111
NOTE — Electrical installation includes the welding Circuit.
work piece
metal piece or pieces on which welding or allied processes are performed
protective clothing and accessories
protective clothing and accessories (e.g. gloves, hand shields, head masks and filter lenses) used in order to diminish electric shock risks and the effects of fume and spatter and to protect the skin and eyes against arc radiation
environments with increased hazard of electric shock
environments where the hazard of electric shock by arc welding is increased in relation to normal arc welding conditions
NOTE I — Such environments are lound br esainple
a> in locations in which treetiom of movement Is restricted, so that the operator is forced to perborm th, welding in a cramped position (kneeling, artling, lying) with physical contact with conductiv. ptls
bi in locations which are fuly or partially limited by conductive elements end in which mare is a hIgh risk of unavoidable or accudental contact by the operator:
c in wet. damp or hot locations where humidity or perspraliori considerably reduces the skin resistance of the human body and the insulating properties at acceaaoe*s
NOTE 2 — Environiri.nls with increased hazard of electric shock are not meant to include plces where electrically conductive pan; in me near vicinity of th, operator which can cause increased hazard have been eniulated
IIEC 60974-1, 34-61
industrial and professional use
use intended only for experts or instructed persons (lEG 60974-1. 3.2)
expert (competent person, skilled person)
a person who can judge the work assigned and recognize possible hazards on the basis of profes5ional training, knowledge, experience and knowledge of the relevant equipment.
