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. 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). NOTE 1 Typical allied processes are, for example, plasma arc cutting and arc spraying. NOTE 2 This document does not include electromagnetic compatibility (EMC) requirements.Cross References:EN 61140:2016IEC 61140EN 60974-7:2013IEC 60974-1:2017/AMD1:2019IEC 60974-1:2017IEC 60974-7:2013EN IEC 60974-1:2018/A1:2019EN IEC 60974-1:2018IEC TS 60479-2EN IEC 60974 (series)EN 60384-14IEC 60384-14IEC 60974 (series)All current amendments available at time of purchase are included with the purchase of this document.
