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 relates to a multi-functional remote controller () for a welding apparatus and a welding current source, which remote controller can be connected to the welding apparatus and the welding current source by at least one line, the remote controller () having setting elements and switching elements and at least one display unit. The remote controller () has a memory, in particular a memory card, and at least one additional interface, in particular a USB terminal, and the various parameters, functions and/or operating modes are set and edited by a menu-driven system.

Remote controller and control unit for a welding device

The invention describes a welding apparatus (), which has a current source () for supplying electrical power to at least one electrode at a welding torch () and a control system () co-operating with the current source (), linked to an input device () for entering settings for different welding parameters, several sensing means being provided for detecting various actual values of a welding process. At least one measuring device or system for sensing mechanical motion, in particular a welding wire displacement and/or a welding torch displacement or similar, is provided, which detects a surface structure of an object.

Detecting element for a welding device

The invention relates to a welding device ( ) having a current source ( ) for supplying electrical energy to at least one electrode and a control and/or evaluation unit ( ) co-operating with the current source ( ), having an input device ( ) for setting various welding parameters, characterised in that a communications interface ( ) connected to the control and/or evaluation unit ( ) is provided in order to set up a two-way data exchange between the welding device ( ) or the current source via a web-server, in particular a HTTP server.

Welding unit equipped with a communications interface and method for operating the welding unit

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 control device for a welding device ( ), consisting of a digital control device ( ), in particular a microprocessor control, and a welding process control unit, comprising a signal processing unit, hereinafter referred to as SP unit, and a pulse width modulator, hereinafter referred to as PWM, and at least one external component, such as a power component ( ) or an input and/or output device ( ), etc., for example. The welding process control is digitally operated by the welding process control unit and the configuration and parameter settings for the welding process control unit are handled by the control device ( ) through software means.

Regulating device for a welding apparatus

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 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.
