Arc welding equipment - Part 2: Liquid cooling systems

IEC 60974-2:2013 specifies safety and construction requirements for industrial and professional liquid cooling systems used in arc welding and allied processes to cool torches. This part of IEC 60974 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 part of IEC 60974 is not applicable to refrigerated cooling systems. This third edition cancels and replaces the first edition published in 2007 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 60974-1:2012; - addition of a liquid temperature fixed to 65 °C during the heating test in order to allow testing at different ambient air temperature (see 10 d)); - correction factor of cooling power at 40 °C required in instruction manual (see 12.1 o)).

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

La CEI 60974-2:2013 spécifie les exigences 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. La présente partie de la CEI 60974 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. La présente partie de la CEI 60974 ne s'applique pas aux systèmes de refroidissement avec réfrigération. Cette troisième édition annule et remplace la seconde édition parue en 2007 et constitue une révision technique. Les modifications techniques majeures par rapport à l'édition précédente sont les suivantes: - modifications induites par la publication de la CEI 60974-1:2012; - addition d'une température du liquide fixée à 65 °C pendant l'essai d'échauffement afin de permettre les essais à différentes températures ambiantes (voir 10 d)); - facteur de correction de la puissance de refroidissement à 40 °C requis dans le manuel d'instructions (voir 12.1 o)).

Oprema za obločno varjenje - 2. del: Hladilni sistemi s tekočino

Ta del standarda IEC 60974 določa varnostne in konstrukcijske zahteve za industrijske in strokovne hladilne sisteme s tekočino, ki se uporabljajo pri obločnem varjenju in podobnih postopkih za hlajenje plamena. Ta del standarda IEC 60974 se uporablja za samostojne hladilne sisteme s tekočino, ki so povezani z ločenim virom varilnega toka ali vgrajeni v ohišju vira varilnega toka. Ta del standarda IEC 60974 se ne uporablja za ohlajevane hladilne sisteme.
