The 555 MMA 400 G utilizes advanced IGBT inverter technology, providing high efficiency, wide input voltage tolerance (380V ±15%), and stable welding performance. It features a digital meter for presetting and displaying welding current, a dust-free cooling system, and an upgraded duty cycle for continuous heavy-duty operation. The machine includes adjustable ARC Force and Hot Start functions, making arc striking easier and more precise, while the VRD (Voltage Reduction Device) function enhances safety for welders.Designed for durability and operator convenience, the 555 MMA 400 G offers auto-protection against over-voltage, over-current, and overheating, with an optional remote control function to enlarge your welding area and simplify operation. This energy-efficient machine outperforms traditional SCR welding machines, reducing power consumption without compromising performance.Technical Specifications:Input: 3-Phase, 50/60 HzInput Power: 27.7 KVA, 41.5 ADuty Cycle: 315A 100% @ 40°C, 400A 40% @ 40°CElectrode Compatibility: Ø7018 (1.6–5mm), Ø6013 (1.6–6mm)Open Circuit Voltage (OCV): 69VCurrent Range: 40–400AOptional VRD for enhanced safety
