Organization: NEMA
Publication Date: 1 January 2019
Status: active
Page Count: 155
scope:

This part of IEC 60974 is applicable to power sources for arc welding and allied processes designed for industrial and professional use, and supplied by a voltage not exceeding 1 000 V, battery supplied or driven by mechanical means.

This document specifies safety and performance requirements of welding power sources and plasma cutting systems.

This document is not applicable to limited duty arc welding and cutting power sources which are designed mainly for use by laymen and designed in accordance with IEC 60974-6.

1DV.1 D2 Modify Clause 1 by replacing the third paragraph with the following:

Welding equipment that has been designed to comply with this standard and is intended for industrial and professional use, and that meets all the scope limitations of the trinational adoption of IEC 60974-6 is suitable for use by laypersons provided the additional instructions and markings requirements of the trinational adoption of IEC 60974-6 are met.

1DV.2 DR Modification to Clause 1 by adding the following:

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. 1.

This document includes requirements for battery-powered welding power sources and battery packs, which are given in Annex O.

This document is not applicable to testing of power sources during periodic maintenance or after repair.

NOTE 1 Typical allied processes are electric arc cutting and arc spraying.

NOTE 2 AC systems having a nominal voltage between 100 V and 1 000 V are given in Table 1 of IEC 60038:2009.

NOTE 3 This document does not include electromagnetic compatibility (EMC) requirements.

1DV.3 D2 Modification to Clause 1 by adding the following:

In Canada, products covered by the scope of this Standard are also subject to the requirements of Annex DVA, Table DVA.3, Ref. No. 15.
