It would also be possible to draw conclusions about the quality of the weld by taking pictures of the weld after the weld has been carried out.
- Certain operating states such as Errors, optically or acoustically displayed on the control and display unit of the welding device during the welding process, so that the person responsible recognizes the error the next time he looks at the welding device and can then correct it.
- Methods are also known in which error messages are forwarded to a control center so that the latter can take appropriate steps to correct the errors or to change the operating state.
- Valuable time often passes before the information about the respective operating state, for example an error during the welding process, arrives at the person responsible and high costs can be incurred due to possible production downtimes.
- the object of the present invention is therefore to provide a method for operating a welding device of the specified type and for creating a welding device of the specified type, by means of which certain operating states can be detected quickly and appropriate steps can be taken automatically to avoid long downtimes, so that the information arrives quickly at a designated recipient via the operating status.
