IEC 60974-13:2021 is available as IEC 60974-13:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60974-13:2021 is applicable to welding current return clamps for arc welding processes, designed to make an electrical connection to the workpiece without using tools. This document is not applicable to welding current return clamps for underwater welding and plasma cutting. This document specifies safety and performance requirements of welding current return clamps. This document does not specify requirements for welding cables. This second edition cancels and replaces the first edition, published in 2011, and constitutes a technical revision. The significant technical changes with respect to the previous edition are the following: – Modified the title from “Welding clamp” to “Welding current return clamp” and updated the term through the document. – Updated all values of test current in Table 1 corrected to 40 Ā°C. – Updated the reference to EN 50565-1:2014, Electric cables – Guide to use for cables with a rated voltage not exceeding 450/750 V (U0/U) ā€“ Part 1: General guidance This part of IEC 60974 is to be used in conjunction with IEC 60974-1.
