Want to know which one is better, small medium frequency spot welding machine or energy storage spot welding machine? We must first know their core differences,Small medium frequency spot welding machineIt is a plug-and-play welding machine that directly uses electricity from the power grid to convert it into direct current for welding. The energy storage spot welder charges first, then stores it, and then uses the stored electricity to weld. Just like a mobile phone, it is one thing to first charge the electricity into the battery and then the mobile phone has power to run. However, the energy storage spot welder uses industrial capacitors to store electricity. This also involves the life of the capacitor. Everyone in the family has used an electric car and knows its lifespan, so the advantages and disadvantages are immediately apparent.
