This part of IEC 60974 specifies safety and performance requirements applicable to limited duty arc welding and cutting power sources, and auxiliaries designed for use by laymen. Electrically powered equipment is intended to be connected to the single phase public low-voltage supply system. Engine driven power sources can not exceed output power of 7,5 kVA.
NOTE 1 This equipment is typically used by non-professionals in residential areas.
This part of IEC 60974 is not applicable to arc welding and cutting power sources that require for operation:
-
arc striking and stabilizing devices;
-
liquid cooling systems;
-
gas consoles;
-
three-phase input supply;
and which are intended for industrial and professional use only.
This part of IEC 60974 is not applicable to arc welding and cutting power sources and ancillary equipment used in:
-
mechanically guided applications;
-
submerged arc welding process;
-
plasma gouging process;
-
plasma welding process;
that are covered by other parts of IEC 60974.
NOTE 2 Power sources, wire feeders, torches and electrode holders designed for industrial and professional use are respectively covered by IEC 60974-1, IEC 60974-5, IEC 60974-7 and IEC 60974-11.
NOTE 3 This part of IEC 60974 does not specify electromagnetic compatibility (EMC) requirements that are given in IEC 60974-10.
