BS638 Part 4 Cable

Welding cables are robust and designed to carry high currents under rough usage conditions and are capable of enduring high temperatures. Welding cable can be found on construction sites, and in welding robots on assembly lines used by the shipbuilding and automotive industries.

Part 4 of this Standard covers single-core flexible cables carrying the welding current in metal arc welding circuits from the welding power source to the electrode holder and workpiece. 

These cables are suitable for use in manual, semi-automatic and automatic welding applications. They have been designed to withstand constant load switching and to operate in challenging environments requiring mechanical robustness.

* Please note, this standard has now been withdrawn, although BS638 Part 4 remains a commonly used reference term.
