Frequency: 20kHz; Power: 2000/3000W;

Introduction: good conductivity after welding, resistance coefficient close to zero, commonly used in copper foil, aluminum foil, battery electrode welding;

Features: welding without sparks, environmental protection and safety; welding materials do not melt, not fragile metal properties; good conductivity after welding, resistance factor is extremely low or near zero; welding time is short, do not need any flux, gas, solder;
