What is BS EN IEC 60974-7- Arc welding equipment about?
BS EN IEC 60974 series covers arc welding equipment. BS EN IEC 60974-7 is one of the parts of a series of documents that specifies safety and construction requirements for torches used for arc welding and allied processes.
BS EN IEC 60974 is applicable to manual, mechanically guided, air-cooled, liquid-cooled, motorized, spool-on, and fume extraction torches. It is also applicable to a cable hose assembly connected between a power source and ancillary equipment.
Note: BS EN IEC 60974-7 is not applicable to electrode holders for manual metal arc welding or air-arc cutting/gouging.
Who is BS EN IEC 60974-7- Arc welding equipment for?
BS EN IEC 60974-8 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 60974-7- Arc welding equipment?
Arc welding equipment is still one of our most useful and time-saving welding machines. Safety is the most important factor when dealing with inflammable gases as humans are directly involved in the welding processes.
When dealing with electrical equipment it is important to ensure they are safe to use. IEC 60974‑7 helps improve the safety and performance of torches in arc welding equipment.
IEC 60974‑7 assists design engineers in developing torches for welding and plasma cutting systems in arc welding equipment according to standard safety requirements.
IEC 60974-7 helps bring global uniformity in arc welding equipment, which increases the market size for users of this document.
What’s changed since the last update?
BS EN IEC 60974-7:2019 supersedes BS EN 60974‑7:2013, which is withdrawn. BS EN IEC 60974-7:2019 includes some technical changes with respect to BS EN 60974‑7:2013. These include:
