A method for automatic determination of machining parameters for a machining process includes selecting certain machining parameters from stored machining parameters on the basis of predefined conditions for machining a workpiece depending on a position along a machining path, determining limit values for the machining parameters of the machining process to be performed, specifying new machining parameters by taking these limit values into consideration, and guiding a machining head along the machining path over the workpiece with the new machining parameters which take the limit values into consideration. If the limit values are not approached or reached, the machining process is continued using the certain machining parameters as the new machining parameters. If the limit values are approached or reached, the machining process is continued using changed machining parameters as the new machining parameters in order to perform the machining process without violating the limit values.

Method for optimizing a maximum power point of a solar cell stack having modules, each including an MLSD unit, and an inverter. The MLSD unit shuts down the module when module voltage falls below a first voltage threshold, and switches it on, when a predefined second voltage threshold is exceeded. For optimal performance, the solar cell stack carries out: Defining, changing an electrical control parameter to a first wait value so that the second voltage threshold is exceeded exceeded; maintaining first wait value for a first time period so the modules are switched on by the MLSD units; changing electrical control parameter to a threshold value in a variation range and determining current-voltage curves for the modules in variation range; determining maximum stack power from current-voltage curves of the modules in the variation range; and predefining the determined maximum stack power as the maximum performance point.

A welding device allows uninterrupted welding with maximum welding quality even in the case of welding processes performed simultaneously in close proximity by several welding devices. In a normal operating mode, the control unit of the welding device ignores a first welding voltage signal of a first voltage-measuring device and uses a second welding voltage signal, detected closer to the are, of a second voltage-measuring device to determine the control parameters. The control unit detects an error state in the second welding voltage signal on the basis of the second welding voltage signal and, upon detecting the error state, switches to an emergency operating mode without interrupting the welding process. In the emergency operating mode, the control unit ignores the second welding voltage signal of the second voltage-measuring device and uses the first welding voltage signal of the first voltage-measuring device to determine the control parameters.

The aim of the invention is to enable a stable welding process. This is achieved in that a welding device is supplied with a supply power by an energy source and converts at least a part of the supply power into a welding power in order to generate a welding arc, wherein the welding power is regulated by specifying a welding current. For this purpose, the supply voltage is determined, and the maximum supply current that can be delivered to the welding device from the energy source is specified. A maximum supply power is calculated using the supply voltage and the maximum supply current. The maximum welding power that is delivered by the welding device is determined from the maximum supply power, and the welding power is limited to the maximum welding power that can be delivered.

In a method for regulating or controlling the conveyance speed of a wire composed of consumable material during a laser soldering or welding method, the wire is melted by a laser beam from a laser unit and is conveyed at a mean conveyance speed toward a workpiece to be processed, wherein a voltage between the wire and the workpiece is measured. A laser soldering or laser welding device carries out this method. In order to avoid at least relatively lengthy short-circuit breaking between the end of the wire and the workpiece, the conveyance speed of the wire, as a function of the measured voltage, is temporarily increased to a predetermined boost speed by increasing the conveyance speed to the predetermined boost speed when a defined voltage limit value is exceeded, and the conveyance speed is reduced again at the latest when the voltage limit value falls below.
