Arc welding equipment -- Part 5: Wire feeders
This part of IEC 60974 specifies safety and performance requirements for industrial and professional equipment used in arc welding and allied processes to feed filler wire. The wire feeder may be a stand-alone unit which may be connected to a separate welding power source or one where the welding power source and the wire feeder are housed in a single enclosure. The wire feeder may be suitable for manually or mechanically guided torches. This part of IEC 60974 is not applicable to spool-on torches that are covered by IEC 60974-7. This part of IEC 60974 is not applicable to wire feeders which are designed for use by laymen and are covered by IEC 60974-6.

Part 5: Wire feeders
FOREWORD 1)
The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2)
The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3)
IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4)
In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5)
IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6)
All users should ensure that they have the latest edition of this publication. 7)
No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8)
Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9)
Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60974-5 has been prepared by IEC technical committee 26: Electric welding. This second edition cancels and replaces the first edition published in 2002 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – changes induced by the publication of IEC 60974-1, edition 3; – IEC 60974-5 is not applicable to spool-on torches that IEC 60974-7 covers (see Clause 1); – IEC 60974-5 is not applicable to wire feeders which are designed for use by laymen that IEC 60974-6 covers (see Clause 1); – wire feeders with degree of protection IP23S may be stored, but are not intended to be used outside during precipitation unless sheltered (see 6.2.1 and Table 1); – withdrawal of voltage limitation for input supply network (see 6.4); – protective connection provision for welding circuit (see 6.5);
60974-5 © IEC:2007 – 5 – – addition of tilting stability (see 10.5); – clarification of the definition of the thermal requirement test. The manufacturer gives the maximum load (see Clause 9); – introduction of rating plate layout for stand-alone wire feeder (see 11.2); – introduction of new combined symbols for liquid/gas input and output based on IEC 60974-1 (see 13.2). The text of this standard is based on the following documents: FDIS Report on voting 26/364/FDIS 26/368/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. This standard shall be used in conjunction with IEC 60974-1 and IEC 60974-7.
The list of all the parts of IEC 60974, under the general title Arc welding equipment, can be found on the IEC web site. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be
• reconfirmed; • withdrawn; • replaced by a revised edition, or • amended.

Part 5: Wire feeders
1 Scope This part of IEC 60974 specifies safety and performance requirements for industrial and professional equipment used in arc welding and allied processes to feed filler wire. The wire feeder may be a stand-alone unit which may be connected to a separate welding power source or one where the welding power source and the wire feeder are housed in a single enclosure. The wire feeder may be suitable for manually or mechanically guided torches. This part of IEC 60974 is not applicable to spool-on torches that are covered by IEC 60974-7. This part of IEC 60974 is not applicable to wire feeders which are designed for use by laymen and are covered by IEC 60974-6. NOTE 1 Typical allied processes are, for example, plasma arc cutting and arc spraying. NOTE 2 This standard does not include electromagnetic compatibility (EMC) requirements. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
