Abstract

The invention relates to a hose assembly (24), comprising a plurality of lines (7; 12; 17; 25) for supplying a welding torch (10) with operating media, such as welding current, welding wire, protective gas, and / or control signals, and having at least one coolant line (19, 19') for feeding a cooling medium of a coolant source (21) to a welding torch (10), and having at least one coupling element (26) for detachably connecting to a welding unit (2) or to a welding torch (10) if necessary. A further coupling element (29) for the at least one coolant line (19, 19') is integrated in the coupling element (26), the coupling and decoupling direction of the further coupling element being oriented perpendicular to a longitudinal axis of the hose assembly (24), wherein the coupling elements (26, 29) can each be coupled and decoupled independently of each other.; The invention further relates to a coupling element (26) designed correspondingly, a connector element (35) used therein or a plug-in connection for the at least one coolant line (19, 19'), and a welding device equipped with said elements.
