WELDING POWER SOURCE AND METHOD FOR CONTROLLING THE SAME

The invention relates to a method for configuring an interface of a welding power source (31, 41, 51, 61, 81, 91), said interface comprising at least one external connection (201 . . . 206). Defined graphic symbols of a software are used for configuration, the edges of said graphic symbols having bulges and/or indentations which interlockingly engage with corresponding bulges and/or indentations of a second graphic symbol. The configuration process comprises the allocation of a parameter of the welding device to an internal and/or external connection (101 . . . 105) and optionally establishing a logic link by stringing the graphic symbols together. The invention further relates to a welding power source (31, 41, 51, 61, 81, 91) and to a computer program which are set up for performing or storing the process according to the invention.
