Arc welding equipment - Part 2: Liquid cooling systems

This part of IEC 60974 specifies safety and construction requirements for industrial and professional LIQUID COOLING SYSTEMS used in arc welding and allied processes to cool torches. This document is applicable to LIQUID COOLING SYSTEMS which are stand-alone (separate from the welding equipment) or built-in (housed in a single enclosure with other welding equipment). This document is not applicable to refrigerated cooling systems. NOTE 1 Typical allied processes are electric arc cutting and arc spraying. NOTE 2 This part of IEC 60974 does not include electromagnetic compatibility (EMC) requirements that are given in IEC 60974-10.

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

La présente partie de l'IEC 60974 spécifie les exigences de sécurité et de construction des SYSTEMES DE REFROIDISSEMENT PAR LIQUIDE industriels et professionnels utilisés en soudage à l'arc et les procédés connexes pour refroidir des torches. Le présent document s'applique aux SYSTEMES DE REFROIDISSEMENT PAR LIQUIDE qui sont indépendants (séparés du matériel de soudage) ou incorporés (intégrés dans une seule enveloppe avec d’autres matériels de soudage). Le présent document ne s'applique pas aux systèmes de refroidissement avec réfrigération. NOTE 1 Le coupage à l’arc électrique et la projection à l'arc électrique sont des exemples de procédés connexes typiques. NOTE 2 La présente partie de l’IEC 60974 ne contient pas les exigences de compatibilité électromagnétique (CEM) qui sont données dans l’IEC 60974-10.

Oprema za obločno varjenje - 2. del: Hladilni sistemi s tekočino (IEC 60974-2:2019)

Ta dokument določa varnostne in konstrukcijske zahteve za industrijske ter profesionalne HLADILNE SISTEME S TEKOČINO, ki se uporabljajo pri obločnem varjenju in podobnih postopkih za hlajenje plamena. Ta dokument se uporablja za samostojne HLADILNE SISTEME S TEKOČINO (ločene od opreme za varjenje) ali za vgrajene (v skupnem ohišju z drugo opremo za varjenje). Ta dokument se ne uporablja za ohlajevane hladilne sisteme.
