This part of IEC 60974 specifies safety requirements for industrial and professional ARC STRIKING and ARC STABILIZING DEVICES used in arc welding and allied processes.<\/p>\n
This document 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 other arc welding equipment).<\/p>\n
\nNOTE 1 Typical allied processes are, for example, plasma arc cutting and arc spraying.<\/p>\n<\/blockquote>\n
\nNOTE 2 This document does not include electromagnetic compatibility (EMC) requirements.<\/p>\n<\/blockquote>\n
