The Xinxing capacitor energy storage spot welding machine is a device that uses capacitor energy storage technology for welding. It charges the capacitor through power frequency AC rectification, and then converts the stored electrical energy into low-voltage, high-energy pulse current through the welding transformer, using resistance heat to achieve metal welding. This welding method has concentrated energy, precise control, strong and beautiful solder joints, and little impact on the power grid.Core features and advantagesEnergy saving and high efficiency: The instantaneous power drawn from the power grid is low, the power factor is high, and the impact on the power grid is small.Small heat-affected zone: The discharge speed is extremely fast, the heat-affected zone is small, and the surface of the weldment is almost tracelessGood quality of solder joints: No discoloration of solder joints, saving grinding process and high efficiency.No water cooling required: Due to the short discharge time, overheating will not occur during long-term use.Wide scope of application: widely used in spot welding of copper/silver/aluminum/nickel and other plates, projection welding of compressor housing seal rings, and spot welding and nut projection welding of high-strength steel and hot-formed steel in the automobile manufacturing industry.
