A welding helmet includes at least one helmet shell, fixing elements, a glare shield device and at least one protective screen spaced therefrom, and at least one display device for presenting data in the field of view of a welder, the at least one display device being arranged in the edge region of the field of view in the intermediate space between the glare shield device and the protective screen. The glare shield device has at least one cut-out in the area of the at least one display device. Because there is no glare shield device in the region of the display device, the view of the display device is not impeded by the glare shield device.

A detection device for detecting a diameter and/or composition of a welding wire and/or welding electrode for a welding device, includes an oscillating circuit, which has a coil through which the welding wire and/or welding electrode can be passed. The device further include an evaluation unit connected to the oscillating circuit for determining at least one first oscillating circuit parameter which is characteristic of an attenuation of an oscillation signal occurring in the oscillating circuit, and at least one second oscillating circuit parameter which is characteristic of a signal frequency f of the oscillation signal occurring in the oscillating circuit. The evaluation unit detects the diameter and/or composition of the welding wire passed through the coil of the oscillating circuit and/or of the welding electrode using the determined oscillating circuit parameters.

Method and device for detecting a welding wire diameter or welding wire composition in a welding device

Power transmission system () for power transmission of electric power (P) from a power source (A) to a power sink (A) which is connected to the power source (A) via a power transfer cable (), wherein the power source (A) has a first pole with a first electric potential, which is connected via parallel current lines of a first conducting pair of the power transfer cable () to a first pole of the power sink (A), and a second pole with a second electric potential, which is connected via further parallel current lines of a second conducting pair of the power transfer cable () to a second pole of the power sink (A), wherein, during the power transmission via the current lines, a user data signal can be transmitted between the power source (A) and the power sink (A) via at least one conducting pair with current lines of the same electric potential, uninfluenced by the power transmission.

Power transmission system

The invention describes a welding device (1) or a current source (2), with a control system (4), preferably comprising a microprocessor controller with a memory unit, a power component (3), in particular a current-inverting source, and additional components such as a welding torch (10), a wire feed device (11), etc., which are connected to the welding device (1) or the current source (2) via appropriate interfaces. An add-on module (27) is connected to the control system (4) or to the current source (2) for identifying a person by means of biometric physical characteristics such as an electronic fingerprint, voice recognition, iris recognition, recognition of a facial shape, recognition of writing, etc. or alternatively a transponder code via a transponder system.

Assessing and/or determining of user authorizations using a transponder, a finger print recognition routine or the like

The invention describes a welding system with a welding device ( ) and a protective device ( ), in particular a protective shield ( ) for a user or welder. The protective device ( ) has an electrically controllable and/or adjustable protective visor ( ) with a control system ( ). The welding device ( ) or the welding system consists of at least one current source ( ), a welding torch ( ) and a control unit. The protective device ( ) has a transmitter and/or receiver unit ( ) which is connected to the control system ( ). The transmitter and/or receiver unit ( ) is connected to the welding system or the welding device ( ) or the welding torch ( ) via a connecting line ( ) or alternatively wirelessly and, when a start switch ( ) disposed on the welding torch ( ) or on the welding device ( ) is activated or when a start command is issued, the control unit or the welding torch ( ) sends a signal via the transmitter and/or receiver unit ( ) to the control system ( ) to darken the protective visor ( ).

Data display on a welding screen

The invention describes a method of operating a data exchange between an external component, in particular a remote control unit ( ), and a welding unit ( ), in particular a current source. A serial data exchange is run between a welding unit ( ), in particular a current source, and an external component, in particular a remote control unit ( ), directly across the welding lines, in particular across the connecting lines ( ) to the welding torch ( ) and to the workpiece ( ), on the basis of digital levels.

Remote regulation unit for a welding apparatus or a power source

The invention describes a method of controlling a welding unit ( ) and a current source ( ), in which various welding parameters, such as a welding current, a welding wire diameter, a welding method etc., for example, can be set by a user from an input and/or output device ( ). The welding unit ( ) and the current source ( ) are then activated by the control device ( ) in accordance with the predetermined welding parameters, different desired values being stored in a memory device for the different welding parameters. The desired values for at least one welding parameter of a welding method are stored in the memory device for the minimum and maximum values in the form of a minimum and maximum curve and when a welding parameter falling between the minimum and maximum values or curves is retrieved or set, the control device ( ) determines the other desired values of the other welding parameters of this welding process by means of a computing method, in particular by means of an interpolation calculation.

Method for controlling a welding apparatus and corresponding control device

The invention describes a method of controlling a welding unit ( ) and a current source ( ), in which various welding parameters, such as a welding current, a welding wire diameter, a welding method etc., for example, can be set by a user from an input and/or output device ( ). The set welding parameters are applied to a control device ( ). The welding unit ( ) and the current source ( ) are then activated by the control device ( ) in accordance with the predetermined welding parameters. Prior to, during and/or after start-up of the welding process, the user can set a surface area or a cross section of a weld seam, in particular a fillet weld, from the input and/or output device ( ), after which the control device ( ) scans and/or retrieves and displays desired values for additional parameters needed to form the weld seam and/or for the welding procedure, stored in a memory device in particular.

The invention relates to a control device (,) for a welding apparatus (,) or a welding facility, comprising a welding torch (,) connected to the welding apparatus (,) via connecting lines, wherein at least one input device (,) and/or a display device (,) are arranged on the welding torch (,). The control device (,) is connected to a serial data bus, in particular a field bus, to which the welding torch (,) and/or additional components of the welding apparatus (,) and/or the welding facility are attached.
