Arc welding equipment - Part 2: Liquid cooling systems

Specifies safety and construction requirements for industrial and professional liquid cooling systems used in arc welding and allied processes to cool torches. Is applicable to stand-alone liquid cooling systems that are either connected to a separate welding power source or built into the welding power source enclosure. This new edition takes into account changes induced by the publication of the third edition of IEC 60974-1 as well as technical changes in the set-up.

Matériel de soudage à l'arc - Partie 2: Systèmes de refroidissement par liquide

Spécifie les prescriptions de sécurité et de construction des systèmes de refroidissement par liquide industriels et professionnels utilisés en soudage à l'arc et techniques connexes pour refroidir des torches. S'applique aux systèmes de refroidissement par liquide indépendants qui sont soit raccordés à une source de courant de soudage séparée soit incorporés dans l'enveloppe de la source de courant de soudage. Cette nouvelle édition tient compte des modifications induites par la publication de la troisième édition de la CEI 60974-1, ainsi que de modifications techniques du montage de simulation.

– 2 – Foreword The text of document 26/362/FDIS, future edition 2 of IEC 60974-2, prepared by IEC TC 26, Electric welding, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60974-2 on 2008-02-01. This European Standard supersedes EN 60974-2:2003. EN 60974-2:2007 includes the following significant technical changes with respect to EN 60974-2:2003: – changes induced by the publication of EN 60974-1:2005; – introduction of a set-up for torch simulation during leakage test; – complementary requirement for attachment plug in 125 V supply network; – introduction of new items in instructions; – correction of density value for water/alcohol (50/50); – improvement of rating plate example. This standard is to be used in conjunction with EN 60974-1:2005. The following dates were fixed: – latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement
(dop) 2008-11-01 – latest date by which the national standards conflicting
