Introduction to Capacitors in Capacitor Energy Storage Spot Welding Machine

The capacitor is the most important component in a capacitor energy storage spot welding machine, accounting for a significant portion of its overall performance. Its charging and discharging speed as well as its lifespan directly impact the overall effectiveness of the equipment. So, let’s dive into what capacitors are commonly available on the market.

According to research, the most common material used for capacitors on the market is aluminum electrolytic capacitors. Generally speaking, the lifespan of these capacitors is relatively low. In many European and American countries, aluminum electrolytic capacitors like Black Diamond, Nichicon, and Rubycon have a lifespan of about 5-6 years. In contrast, domestically produced capacitors typically have a lifespan of 1-2 years. Therefore, in the field of energy storage welding machines, the use of foreign capacitors like Black Diamond is more common.

Capacitors inevitably generate heat during use. For every 5°C increase in operating temperature of the capacitor, its lifespan decreases. Here, we recommend using smaller capacitors because they generate less heat during charging and discharging. When using smaller capacitors, more capacitors need to be connected in parallel for the same capacity equipment, which greatly reduces the internal resistance generated during capacitor charging and discharging. This leads to shorter discharge times, higher welding currents, and is beneficial for welding and protecting workpieces.
