Energy storage spot welders, due to their simple working principle of energy charging and releasing, have a simple structure and configuration. They have been widely used for a long time, especially in low-power applications. Many companies both domestically and internationally produce them, including brands like Nimak abroad and Agers, Haron, etc., domestically.
Which brand of energy storage spot welder is good? For low-power energy storage spot welders with an input voltage of typically 220V and energy within 3000 joules, mainstream manufacturers both domestically and internationally can produce them. The differences mainly lie in control accuracy, component brands, manufacturing processes, etc. Domestic first-tier brands can mass-produce them, and the domestic market is highly competitive in this category, with almost no application of foreign brands because domestic technology is mature enough.
Which brand of energy storage spot welder is good? There are significant differences in high-power capacitor energy storage spot welders domestically, particularly those with capacities of over 10,000 joules. They are generally referred to as large capacity, with discharge currents reaching up to 100,000 amperes. Their control methods and structures differ significantly from small-scale energy storage welders, with much larger structures and 380V input voltage. The differences between different brands are obvious; firstly, there is a difference between integrated and split structures. Split-type capacitor cabinets have a separate external box structure, while integrated capacitor cabinets are integrated with the body.
In terms of capacitors, there are conventional low-voltage aluminum electrolytic capacitors, medium-voltage metal film capacitors, and high-voltage capacitors. In terms of control methods, there are controllable silicon discharge and IGBT inverter discharge. Foreign brands like Nimak use high-voltage capacitors and integrated bodies, resulting in compact equipment with high output peaks. Domestic brands such as Anjia and Henglong use medium-voltage metal film capacitors and integrated bodies, which are at the same technical level as foreign products. Thanks to the rapid development of capacitor technology and industry technical validation, the theoretical lifespan of custom metal film capacitors is infinite, while ordinary aluminum electrolytic capacitors begin to decay after 5 million cycles. Compared to traditional energy storage welders where capacitors fail or explode one after another after three years, metal film capacitor energy storage spot welders have a revolutionary improvement, and this technology faces barriers domestically.
