One-side welding enameled wire to copper foil with spot welding inverter

In spot welding of enameled wire to copper foil,selecting the appropriate welding electrodes and controlling the welding energy precisely are very important.In this paper,a special loop structure electrode is used.Three-stage pulse current is exported by the sophisticated inverter welding power supply to do one-side welding experiment.Through precise control of welding process parameters,one-side welding enameled wire to copper foil is realized.The actual welding results showed that inverted welding power supply can control the welding energy precisely to meet the needs of copper and enameled wire welding.
