IEC 60974-2:2013 specifies safety and construction requirements for industrial and professional liquid cooling systems used in arc welding and allied processes to cool torches. This part of IEC 60974 is applicable to stand-alone liquid cooling systems that are either connected to a separate welding power source or built into the welding power source enclosure. This part of IEC 60974 is not applicable to refrigerated cooling systems. This third edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - changes induced by the publication of IEC 60974-1:2012; - addition of a liquid temperature fixed to 65 °C during the heating test in order to allow testing at different ambient air temperature (see 10 d)); - correction factor of cooling power at 40 °C required in instruction manual (see 12.1 o)).
