Specifies safety requirements for industrial and professional arc striking and arc stabilizing devices used in arc welding and allied processes. Is applicable to stand-alone arc striking and arc stabilizing devices that are either connected to a separate welding power source or built into the welding power source enclosure. This new edition takes into account changes induced by the publication of the third edition of IEC 60974-1 as well as technical changes in the routine test for the built-in unit.
