記載のアーク溶接用電源。[Claims for Utility Model Registration] 1. An arc welding power source in which a DC-DC converter is configured using a switching unit in which a plurality of small-capacity semiconductor switching elements are connected in parallel to obtain a large output current, The switching unit has two long conductors stacked one on top of the other insulated from each other, the switching elements are arranged in parallel in the length direction of the conductors, and the input and output terminals of the switching elements are connected to the respective input and output terminals of the switching elements. An arc welding power source configured by connecting each conductor at the shortest distance. 2. The arc welding power source according to claim 1, wherein each of the conductors has a connecting protrusion corresponding to the arrangement of the switching elements. 3. The arc welding power source according to claim 1 or 2, wherein the switching elements are arranged on both sides of the two conductors at geometrically symmetrical positions. 4. The switching element is one in which either the input or output terminal is not insulated from the switching element body, and the switching element is directly attached to one of the conductors, thereby making it possible to connect the conductor and the switching element. The arc welding power source according to claim 1, which is a utility model, and has a structure in which it is directly connected to one terminal.
