Abstract: Operating panel (1) for a welding device (SG) comprising a welding parameter display unit (2) for displaying welding parameters, and comprising at least one operating element (3) which can be actuated manually by a user, wherein the operating panel (1) can be switched between a welding parameter selection mode and a welding parameter editing mode by actuating the operating element (3), wherein in the welding parameter selection mode one of the welding parameters of the welding parameter display unit (2) can be selected by rotating the operating element (3), and wherein in the welding parameter editing mode a parameter value of a selected welding parameter of the welding parameter display unit (2) can be set by rotating the operating element (3).

Abstract: System (1) for supplying relevant device information for an energy device (2), wherein the dynamically generated code outputted by the output unit (2E) of the energy device (2) is captured by a mobile terminal (3) of the user, and wherein, after the captured dynamically generated code is successfully decrypted by a decryption unit (3D) of the mobile terminal (3), the mobile terminal (3) establishes a data connection to a server (6) which supplies device information data for the energy device (2) which are relevant for the context specified in the context data.

Abstract: The invention relates to a welding device (1), comprising a connection (27) for a welding torch (7) for performing a welding process, a power source (2) for supplying the welding torch (7) with a welding current, a control device (4) and an input/output device (18), formed by a touch screen (21) and connected to said control device (4), for setting/displaying parameters, functions and the like. In order to make the welding device (1) as easy to operate as possible and allow parameters to be changed quickly on the touch screen (21), the control device (4) is designed for the sequential and circumferential setting/display of parameters in a main area (28) of the touch screen (21), wherein the settable parameter is displayed emphasised in the centre of the main area (28).

Abstract: An adjustment aid (29) for a component of a welding device (1) in the form of an element for mounting or fastening on an input and/or output unit (18) of the component, on which element additionally information (31) and/or scale (32) for adjusting a welding process are printed is provided. In order to simplify the adjustment of a certain welding process by the user, it is provided that the element is formed by a flexible element or foil (30) with two openings (33) for mounting or fastening on two rotary knobs (34) of the input and/or output unit (18), the openings each having a first part (38) and a second part (39), wherein the first part (38) of each opening (33) is designed for guiding through a rotary knob (34) and the second part (39) of each opening (33) is formed for fixation between the two rotational axes (37) of the rotatory knobs (34).
