Resistance welding - Transformer-rectifier for welding guns with integrated transformers - Transformer-rectifier units operating at 1000 Hz frequency (ISO 22829:2007)
ISO 22829:2007 is applicable to transformer-rectifier units as used in electric resistance welding machines operating from a power supply with a frequency of 1 000 Hz, and of a rated value of the input voltage equal to or higher than 500 V. These transformer-rectifier units are primarily used in welding guns with an integrated transformer.
For these transformer units, ISO 22829:2007 supplements the requirements given in ISO 5826 and ISO 10656, which remain applicable except where amended by ISO 22829:2007.

Diese Internationale Norm ist anwendbar für Transformatoren-Gleichrichtereinheiten die in Widerstandspress¬schweißmaschinen eingesetzt werden. Die Frequenz der Eingangsspannung ist auf 1 000 Hz festgelegt. Die Höhe der Eingangsspannung beträgt 500 V oder mehr. Die Transformatoren-Gleichrichtereinheiten werden überwiegend in Schweißzangen mit integriertem Transformator eingesetzt.
Die vorliegende Internationale Norm für Mittelfrequenztransformatoren ergänzt die Normen ISO 5826 und ISO 10656, welche anwendbar bleiben, soweit sie nicht durch die vorliegende Internationale Norm geändert werden.

L'ISO 22829:2007 est applicable aux transformateurs-redresseurs utilisés dans les machines électriques de soudage par résistance alimentées sous une fréquence de 1 000 Hz, et dont la valeur nominale de la tension d'alimentation est égale ou supérieure à 500 V. Ces transformateurs-redresseurs sont surtout utilisés avec des pistolets de soudage à transformateur incorporé.
L'ISO 22829:2007 complète, pour ces transformateurs, les exigences énoncées dans l'ISO 5826 et l'ISO 10656; ces exigences restent applicables lorsqu'elles ne sont pas amendées par l'ISO 22829:2007.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22829 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 6, Resistance welding.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 6 via your national standards body. A complete listing of these bodies can be
found at www.iso.org.
