Overview
This standard of the DIN EN 60974 (VDE 0544) series "Arc welding equipment" shall be applied together with basic standard DIN EN 60974-1 (VDE 0544-1). It specifies safety and construction requirements for industrial and professional liquid cooling systems used in arc welding and allied processes to cool torches. With respect to the previous edition, additional specifications have been added, such as the liquid temperature has been fixed to 65 °C during the heating test in order to allow testing at different ambient air temperatures. The responsible committee is DKE/K 361 "Lichtbogenschweißeinrichtungen" ("Electric arc welding equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
