Embodiment Construction

[0049] The drawing schematically shows a first advantageous embodiment of the welding machine according to the invention, which is designated as a whole with the reference numeral 10. The welding machine 10 has a control unit 12 and a power unit 14 which is controlled by the control unit 12 to which welding guns, which are known per se and are therefore not shown in the drawings for a better overview, can usually be connected to the power unit. The welding machine 10 also has an input device 16 and a display device 18 for inputting control instructions and software programs. In the illustrated embodiment, the display device 18 has multiple seven-segment displays.

[0050] The user 19 can usually use the welding machine 10 to complete different welding tasks. The user 19 can expand the functions of the welding machine 10. To this end, the user 19 can purchase a storage medium in the form of a memory card 20 in the illustrated embodiment, and the input device 16 can read the memo...

Abstract

A method for extending the functionality of an electric welding apparatus having a programmable control unit and an input device is provided. In order to provide the user with greater latitude for a desired functional extension while nevertheless ensuring that unauthorized functional extension can be prevented, a control command for a desired functional extension is issued to the control unit and the control unit uses the control command or the functional extension to generate an apparatus code which is transmitted to an external verifying facility. The external verifying facility uses the apparatus code to verify entitlement to the functional extension and, if entitlement exists, generates an external activation code which is transmitted to the control unit. The control unit then verifies the validity of the external activation code and, if it is valid, implements the functional extension. A welding apparatus for carrying out the method is also proposed.

Description

Technical field [0001] The invention relates to a method for expanding the functions of an electric welding machine, which has a programmable control unit and an input device. [0002] In addition, the present invention also relates to an electric welding machine for performing the method, wherein the welding machine has a programmable control unit and can expand the functions of the welding machine, and wherein the welding machine has an input device. Background technique [0003] An electric welding machine for electric welding of a workpiece usually includes a control unit, a power part, and a welding gun that can be connected to the power part and has a welding electrode. An arc is generated between the welding electrode and the workpiece to be welded, and a weld is generated under the action of the arc. The power part provides the welding voltage and the welding current required for this purpose. The control unit controls the power unit and usually has an input device and a ...
