Abstract

The invention relates to a connection device (27) comprising a coupling device (24) and a plug element (34) for a welding torch (10) connected to the coupling device (24) by at least one hose assembly (23), said coupling device arranged at least partially in the housing, wherein a welding wire (13), delivered by a feed unit (29) which is arranged on a motor plate (28), and additional media are conducted to the welding torch (10) via the hose assembly (23) and wherein the hose assembly (23) is connected to the plug element (34). In order to create such a connection system (27), the coupling device is formed by a connection device (30) comprising an end wall (38) and a separating wall (39) of the motor plate (28), wherein the end wall (38) is designed to receive the coupling (35), the connection device (30) is constructed to at least guide and position a pin (37), and the connection device (30) is independent of the housing.
