The capacitor storage welder charges the capacitor after the AC current is rectified by the rectifier.The stored electrical energy is then released by the welding transformer and converted into a low-voltage, relatively concentrated and stable pulse current.Resistance heat is generated at the contact point of the welding workpiece to weld the metal.

Therefore, capacitors occupy a large part of the energy storage machine.Its charging and discharging speed and service life directly affect the overall effect of welding machine.Currently, in the resistance welding industry, it is usually an emergency charging capacitor.It has excellent performance: instantaneous discharge;One million times charge and discharge performance guarantee.The commonly used models are ECST4H1LGB2C1TCB0M 50 * 110 and ECST4H1LGN102MEE5M 76 * 145.The former is often referred to as a small capacitor, while the latter is often referred to as a large capacitor.

Energy-storage welders with small capacitors have a small capacity, resulting in less heat during charging and discharge, and heat to the life of the capacitor (for every 5 degrees Celsius increase in operating temperature capacitors, the life is halved). In addition, when the same capacity of energy storage welders using small capacitor types, the need to parallel more capacitors, which will greatly reduce the capacitor in the process of charge and discharge resistance, thereby reducing the discharge time. And the current is larger, more conducive to welding and protection of workpieces, so it is best to use small capacitors.
