The welding unit (1)

The invention describes a method of controlling a welding unit (1) and a current source (2), 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 (22). The welding unit (1) and the current source (2) are then activated by the control device (4) 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 (4) 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.
