A hose assembly includes a plurality of lines for supplying a welding torch with operating media, such as welding current, welding wire, protective gas and/or control signals. The lines include a coolant line for feeding cooling medium of a coolant source to a welding torch. The hose assembly has a coupling element for detachably connecting to a welding unit or to a welding torch. A further coupling element for the coolant line is integrated in the coupling element. The coupling and decoupling direction of the further coupling element is orientated transverse to the longitudinal axis of the hose assembly. The coupling elements can each be coupled and decoupled independently from each other. A plug element is used in the coupling element. The coolant line has a plug connection.

Hose assembly and coupling device for a welding device

The invention relates to a connection device () comprising a coupling device () and a plug element () for a welding torch () connected to the coupling device () by at least one hose assembly (), said coupling device arranged at least partially in the housing, wherein a welding wire (), delivered by a feed unit () which is arranged on a motor plate (), and additional media are conducted to the welding torch () via the hose assembly () and wherein the hose assembly () is connected to the plug element (). In order to create such a connection system (), the coupling device is formed by a connection device () comprising an end wall () and a separating wall () of the motor plate (), wherein the end wall () is designed to receive the coupling (), the connection device () is constructed to at least guide and position a pin (), and the connection device () is independent of the housing.
