Product Details
Preface
This is the harmonized ANCE, CSA Group, and NEMA standard for Arc Welding Equipment — Part 1: Welding Power Sources. It is the first edition of NMX-J-038-1-ANCE; Section 1, the first edition of CSA C22.2 No. 60974-1, and the second edition of ANSI/NEMA/IEC 60974-1. This edition of CSA C22.2 No. 60974-1 replaces CAN/CSA-E60974-1:12 (adopted IEC 60974-1:2012) and CSA C22.2 No. 60-M1990.
This harmonized standard is based on IEC publication 60974-1: fifth edition, Arc welding equipment — Part 1: Welding power sources, issued February 2017. IEC 60974-1 is copyrighted by the IEC.
In Canada, for general information on the Standards of the Canadian Electrical Code, Part II, see the preface of CAN/CSA-C22.2 No. 0.
This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. This American National Standard is an adoption of IEC 60974-1 edition 5, Arc Welding Equipment — Part 1: Welding Power Sources, and was developed and approved in accordance with procedures set forth by the American National Standards Institute.
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.
