BS EN IEC 60974-13:2021

What is IEC 60974‑13 about?  

IEC 60974‑13 is one of the parts of a multi-series standard IEC 60974 which is applicable to welding current return clamps for arc welding processes, designed to make an electrical connection to the workpiece without using tools. 

IEC 60974‑13 document specifies the safety and performance requirements of welding current return clamps. 

Note: IEC 60974‑13 is not applicable to welding current return clamps for underwater welding and plasma cutting and does not specify requirements for welding cables. 

Who is IEC 60974‑13 for? 

IEC 60974-13 on Arc welding equipment is applicable to: 

• Construction, automotive, mechanical Industries 
• Sheet metal manufacturers 
• Manufacturers of pressure vessels 
• Manufacturers of aircraft & aerospace 
• Welding equipment manufacturers 
• Shipbuilding industry 

Why should you use IEC 60974‑13? 

When dealing with electrical equipment it is important to ensure they are safe to use by end-user. IEC 60974‑13 helps improve the safety and performance of welding current return clamps in Arc welding equipment. 

IEC 60974‑13 aids in the designation of welding current return clamps by the range of cross-section area of the welding cable intended to be connected with respect to test current. 

IEC 60974-11 helps bring global uniformity in welding equipment, which increases the market size for users of this document. 

What’s changed since the last update? 

BS EN IEC 60974‑13:2021 supersedes BS EN 60974‑13:2011, which is withdrawn. 
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 °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) – Part 1: General guidance
