标准摘要
[中文适用范围]： IEC 60974 的这一部分规定了用于弧焊和相关工艺冷却焊枪的工业和专业液体冷却系统的安全和结构要求。本文件适用于独立（与焊接设备分开）或内置（与其他焊接设备安装在单个外壳中）的液体冷却系统。本文件不适用于冷冻冷却系统。注 1：典型的联合工艺是电弧切割和电弧喷涂。注 2：IEC 60974 的本部分不包括 IEC 60974-10 中给出的电磁兼容性（EMC）要求。 [外文原描述]： IEC 60974-2:2019 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 fourth edition cancels and replaces the third edition published in 2013 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) changes induced by the publication of IEC 60974-1:2017; b) reference in 11.1 changed.
英文名称Arc welding equipment - Part 2: Liquid cooling systems
