This industrial spot welding machine utilizes advanced Medium Frequency (MF) Inverter DC technology to deliver superior welding quality and efficiency compared to traditional AC welders. It converts three-phase AC power into stable DC power, resulting in a consistent welding current with no inductance. This design ensures higher heat input and output efficiency, producing reliable and stable welds, even on challenging materials like aluminum and galvanized steel, or very thin products. The machine features an intelligent digital controller for precise and fast current control, a user-friendly touch screen for data input and monitoring, and a robust build for durability in demanding factory environments. It is designed to reduce production costs, save energy, and minimize maintenance.
