Abstract

In electric welding machines and hot flame machines By connecting a second DC power supply unit's output to the circuit being Supplied by the first power supply unit. Where the DC high voltage from the second DC power supply unit is supplied during start-up, across the Electrode pole And base metals that do not touch each other Wherein the interference from radiating Radiation is significantly reduced. And the high frequency energy loss from the extension cable is eliminated. Which makes the start of the spark a constant
