Abstract
The invention relates to a power jack (27) for a welding device (1), in particular an electrode and/or TIG welding device, wherein the power jack (27) made of conductive material comprises a bore (28) for receiving a plug element (29) attached to a hose packet, and an axial guide groove (33) is disposed in the bore (28), the guide groove being guided to the outside by way of a longitudinal groove (34) such that a locating pin (35) disposed on the plug element (29) can be inserted and rotated, wherein in the bore (28) a radial groove (36) is disposed and a retaining element (38) is positioned, preferably in the intersecting region of the groove (36) and the longitudinal groove (34), and a spring element (40) designed to transmit power is disposed in the groove (36), the spring element (40) protruding from the groove (36) and thereby reducing the diameter of the bore (28), wherein the retaining element (38) forms a contact surface (41) for the ends of the spring element (40) which is configured over only part of the entire periphery.
