IEC 60974-6:2010 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 can not exceed output power of 7,5 kVA. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:<br /> - extension of the scope;<br /> - amendment of the title;<br /> - touch current at fault condition (see 6.3.7);<br /> - new definition of thermal requirements based two independent devices, one for thermal protection and one for thermal control (see 7.1);<br /> - new definition for thermal performances at 20 °C (see 7.2);<br /> - thermal safety requirements are based on operating temperature for normal condition and maximum temperature in overload condition (see 7.4);<br /> - addition of abnormal operation test for t
