What is BS EN IEC 60974‑3 - Arc striking and stabilizing devices about?
BS EN IEC 60974 series covers arc welding equipment. BS EN IEC 60974-3 is one of the parts of a series of documents that specifies safety requirements for industrial and professional arc striking and stabilizing devices used in arc welding and allied processes.
BS EN IEC 60974‑3 is applicable to arc striking and stabilizing devices which are stand-alone (Separate from the welding equipment) or built in (housed in a single enclosure with another arc welding equipment).
Note: BS EN IEC 60974‑3 does not include electromagnetic compatibility (EMC) requirements.
Who is BS EN IEC 60974‑3 - Arc striking and stabilizing devices for?
BS EN IEC 60974‑3 on arc welding equipment is applicable to:
- Construction, automotive, mechanical Industries
- Sheet metal manufacturers
- Manufacturers of pressure vessels
- Manufacturers of aircraft & aerospace
- Shipbuilding industry
- Welding equipment manufacturers
Why should you use BS EN IEC 60974‑3- Arc striking and stabilizing devices?
Arc welding equipment is still one of our most useful and time-saving welding machines. Since, safety is the most important factor when dealing with inflammable gases, safety guidelines need to be put in place to make the usage of inflammable materials safer.
When dealing with electrical equipment it is important to ensure they are safe to use. IEC 60974‑3 helps improve the safety and performance of arc striking and stabilizing devices in arc welding equipment.
IEC 60974‑3 assists design engineers in developing torches for welding and plasma cutting systems in arc welding equipment according to standard safety requirements.
IEC 60974-3 helps bring global uniformity for arc striking and stabilizing devices in arc welding equipment, which increases the market size for users of this document.
What’s changed since the last update?
BS EN IEC 60974‑3:2019 supersedes BS EN 60974‑3:2014, which is withdrawn. BS EN IEC 60974‑3:2019 includes some technical changes with respect to BS EN 60974‑3:2014. These include:
- Changes induced by the publication of IEC 60974-1:2017
- Reference to IEC 60974-1:2017/AMD1:2019 in Clause 2
- Figure 2 is updated where subtraction of the proportion of the no-load voltage is shown
- Requirement for safe operation of the arc striking and stabilising devices in the event of failure, in 11.5
- Requirements for the rating plate as in IEC 60974-1:2017, Clause 15
