300J 4.5KA 0.5MPa Ultra Resistance Welding Machine Energy Storage Spot Welder

300J Energy storage spot welder

Capacitive energy storage spot welding machine, is the use of power frequency alternating current through the rectifier rectifier after charging to the capacitor, the stored electrical energy is then discharged by the welding transformer into a low electrical voltage, the energy is more concentrated and stable pulse current, through the contact point of the welded workpiece to generate resistance heat to weld the metal. Features: No need for current limiting resistors to reduce heat generation. · The solder joints are not blackened, eliminating the need for sanding. · The internal power supply voltage regulator device ensures that the output voltage is constant and the welding consistency is good. · Full digital control, good precision. World famous factory original devices, quality assurance. · This machine is designed to operate simply, eliminating complex tuning and teaching procedures, and the welding effect is good. · Main welding materials: stainless steel, brass, alloy copper, aluminum alloy, etc.
