Product Overview:

The SMD-80 aluminum spot welder represents the current state-of-the-art in welding equipment. Its welding transformer features a compact size with high output energy. By elevating the transformer frequency from standard 50/60Hz to 1000Hz, it significantly reduces core material weight. Additionally, rectifier diodes in the secondary circuit convert AC to DC power for the welder, substantially improving secondary inductance values and saving over 30% in user power consumption. All our aluminum spot welders feature digital control via a user-friendly touchscreen interface, ensuring intuitive operation. Performance can be expanded through PC programming. Custom fixture designs accommodate diverse workpiece welding requirements, and we develop automated special-purpose machines to enhance production efficiency.
