Main Features

Employs advanced MFDC (Mid Frequency Direct Current) inverter technology with over 90% conversion efficiency, saving 30-50% energy compared to traditional AC welders and reducing grid load. Its ultra-short welding time (in milliseconds) significantly boosts production rates.
Provides stable MFDC output, resulting in uniform nugget formation, minimized spatter, and elimination of weak welds. This ensures high joint strength with a smooth finish, making it ideal for welding highly conductive materials (e.g., aluminum, copper) and multi-layer plates.
Features digital PLC or microprocessor control for precise adjustment of current, time, and pressure parameters, supporting storage of multiple welding programs. An automatic compensation function counteracts the effects of grid fluctuations or surface oxidation on workpieces.
Designed for easy integration with robotic arms and conveyors to achieve fully automated production lines. Can be equipped with photoelectric sensors or vision systems for accurate weld joint positioning, ideal for streamlined assembly operations.
The mid-frequency transformer is compact, generates less heat, and boasts a long service life. An efficient water-cooling system ensures the equipment operates continuously and stably under high-duty cycles, minimizing maintenance needs.
Application scope: Door hinges, seat frames, battery connectors, etc. Projection welding of nuts/bolts, metal mesh welding.Spot welding for metal casings, brackets, and internal supports.
