The Panasonic YD-400AT3DJG is a heavy-duty 400A IGBT inverter DC arc (MMA) welding machine engineered for superior performance in industrial fabrication, construction, shipbuilding, and maintenance applications. Built with Panasonic's proven inverter technology, it delivers a stable welding arc, excellent efficiency, and reliable performance even under demanding working conditions.
Designed with a 4-digit 7-segment LED display for both current and voltage, the machine provides accurate parameter monitoring for improved welding quality. The advanced 3-tier and 4-cabinet dust-free structure, combined with hermetically sealed electronic chambers, protects critical components from dust and increases machine life. The integrated Voltage Reduction Device (VRD) enhances operator safety by reducing open-circuit voltage to below 13V DC.
The YD-400AT3DJG also supports Scratch TIG welding, making it a versatile solution for industrial fabrication and repair work.
