| 摘要 |
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 s 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, characterized in that 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 (59) of the further coupling element being orientated transverse to the longitudinal axis (41) of the hose assembly (24), wherein the coupling elements (26, 29) can each be coupled and decoupled independently from each other. The invention further relates to a coupling element (26) designed correspondingly, a plug element (35) used therein or a plug connection for the at least one coolant line (19, 19′), and a welding device equipped with said elements. |
