ICS Code (Welding equipment): 25.160.30
scope:

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 cannot 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.

NOTE 4DV Welding equipment that has been designed to comply with Table DVA.3, Ref. No. 1, and that is intended for industrial and professional use, and that meets all the scope limitations of this standard, is suitable for use by laypersons, provided the additional instructions and markings requirements of this standard are met.

The following power sources for arc-welding and plasma cutting complying with at least onethe following conditions are out of scope of this standard:

a) have an internal combustion engine;

b) have a nominal three-phase supply voltage;

c) have a single rated supply voltage greater than or equal to 220 V; or

d) have multiple nominal supply voltages that do not include a nominal voltage of power supply less than or equal to 127 V single phase.

Power sources meeting these conditions are exempt from NOM-003 and are normally covered in the trinational adoption of IEC 60974-1 listed in Table DVA.3, Ref. No 1.

This equipment is intended for installation in accordance with the national installation codes for use in ordinary locations. See Annex DVA, Table DVA.3, Ref. No. 2.

In Canada, products covered by the scope of this Standard are also subject to the requirements of Annex DVA, Table DVA.3, Ref. No. 3.

All references to IEC 60974-1 contained in this standard include all deviations in Table DVA.3, Ref. No 1.
