Energy Storage Spot Welding Machine | Capacitor

Capacitive Energy Storage Spot Welding Machine uses power frequency alternating current to charge the capacitor after being rectified by the rectifier. The stored electric energy is then converted into a pulse current with low electric voltage and relatively stable energy through the discharge of the welding transformer. The metal is fused through the resistance heat generated at the contact point of the welder. It can weld common ferrous steel, iron and stainless steel, copper, aluminum, silver, nickel, molybdenum, titanium, alloy, galvanized, hot formed steel, high strength steel, low carbon steel, coated steel and other metal materials, and used as welding between dissimilar metals, can do single side single point, single side double point and double side double point welding.

Application

Capacitive Energy Storage Spot Welding Machine is mainly used in automobiles, watches, hardware, furniture, household appliances, household kitchenware, metal utensils, motorcycle accessories, electroplating industry, toys, lighting, batteries, and microelectronics, glasses and other industries.

In the heating industry, it is mainly used for welding between the Resistance Wire and the terminal needle, as well as the welding of the terminal needle and the insert.

Advantages

1. Low requirements on the power grid, and does not affect the power grid, small impact on the power grid, energy saving. Because the principle of the energy storage welding machine is to charge the capacitor through a low-power transformer, and then discharge the workpiece through a high-power solder resistance transformer, it is not easy to be affected by power grid fluctuations.
2. The discharge time is short and the thermal effect is small. Because the discharge time is less than 20ms, the resistance heat generated by the parts is also conductive and diffused, the welding process has been completed and began to cool, so the deformation and discoloration of the welded parts can be reduced to very small.
3. Welding energy is stable. Since each charging voltage reaches the set value, it will stop charging and turn into discharge welding, so the welding energy fluctuation is minimal, ensuring the stability of welding quality. Solid welding, solder joint without discoloration, saving grinding process, high efficiency.

The large current is suitable for multi-point ring convex welding and pressure seal convex welding process. The low-power energy storage welding machine is suitable for welding precision parts, and the high-power energy storage welding machine is suitable for multi-point projection welding, ring projection welding, and sealing projection welding.

1. No need for water cooling, saving energy. Because the discharge time is very short, long-term use will not produce overheating, the discharge transformer and some secondary circuits of the energy storage welding machine almost do not use water cooling.
