Megatec Inverter Welding Machine En 60974-1

The IEC 60974-1 standard pertains to arc welding equipment, specifically welding power sources. Let’s break down what this standard covers:

Scope:
IEC 60974-1 applies to power sources used for arc welding and allied processes.
These power sources are designed for industrial and professional use.
They are supplied by a voltage not exceeding 1000 V and can be either battery-powered or driven by mechanical means.
The document specifies safety and performance requirements for welding power sources and plasma cutting systems.
Note that it does not cover limited duty arc welding and cutting power sources intended mainly for laymen, which are addressed in IEC 60974-6.
Additionally, the standard includes requirements for battery-powered welding power sources and battery packs (see Annex O).
It does not apply to testing of power sources during periodic maintenance or after repair.
Allied processes covered include electric arc cutting and arc spraying.
Electromagnetic compatibility (EMC) requirements are not included1.
