IEC 60974-6:2015 specifies safety and performance requirements applicable to limited duty arc welding and cutting power sources and auxiliaries designed for use by laymen. Electrically powered equipment is intended to be connected to the single phase public low-voltage supply system. Engine driven power sources cannot exceed output power of 7,5 kVA. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:

- modified measurement conditions (see 7.3.1);

- improved values for temperature limits according to the class of insulation (see Table 1);

- improved maximum temperature limits (see Table 2);

- deleted overload test.


This publication is to be read in conjunction with IEC 60974-1:2012.
