DETAILED DESCRIPTION OF THE INVENTION 1. Title of the Invention DC Welding Power Supply Unit 2. Scope of Patent Application (1) The DC welding apparatus employs a melting or non-melting pole welding and has the following characteristics. It has the advantages that the output terminals of a plurality of inverter apparatuses are connected in parallel with each other The circuit formed by the inverter firstly converts the first direct current into alternating current and then the second direct current after the alternating current rectification as the output, and also detects the detection loop of the synthesized output current of each inverter device, and according to the magnitude of the combined current, Circuit to change the number of inverter devices required to access.
