Welding power source and method for controlling the same

A welding power source of a welding device having an interface, comprising:

• an input configured to input at least one value for at least one parameter of the welding power source, the interface comprising a plurality of external connections collectively configured to connect to a single external machine, the interface further comprising at least one internal connection, wherein:
• the interface is represented on an operating display panel as a graphic interface symbol of its at least one internal connection and of at least one of its plurality of external connections,
• the interface provides one or more interface functions, the functions being represented on the operating display panel as graphic interface function symbols, such that a graphic interface function symbol is arrangeable on the operating display panel between at least one internal connection and at least one external connection of the graphic interface symbol in order to functionally link at least one internal connection with at least one external connection via the allocated interface function, wherein:
• on the operating display panel, an outer form of the graphic interface function symbols and of the graphic interface symbol is configured such that the graphic interface function symbols and the graphic interface symbol fit together like puzzle pieces and/or match in terms of color when the allocated interface functions functionally match at least one internal connection and at least one external connection of the interface;
• and
• on the operating display panel, the outer form of the graphic interface function symbols is configured such that the graphic interface function symbols fit together like puzzle pieces and/or match in terms of color when the allocated interface functions match one another functionally;
• the graphic interface symbol and the graphic interface function symbols are usable for configuring the interface;
• a parameter of the welding device is displayed in a parameter region of the operating display panel;
• the graphic interface symbol of the at least one external connection is displayed in an output region of the operating display panel;
• the input is configured to allocate the parameter of the welding device to at least one of an internal and external connection by a user activating on the operating display panel a linking region connecting the parameter region and the output region, the input further configured for establishing a logical link of the interface functions via the linking region by stringing together the graphic interface function symbols presented to the user on the operating display panel.
