STAR ARC heavy-duty MMA-400 Wide Voltage Inverter Welding Machine, a professional-grade power supply specifically optimized for Manual Metal Arc (MMA/Stick) welding in environments with highly unstable power grids.
Based on the interface markings and internal architecture configurations for this class of industrial hardware, the key technical features include:
WELDING RODS: 2.25MM TO 4.0MM
Ultra-Wide Voltage & Power Technology
• Wide Voltage Range (AC 160V – 560V): The primary standout feature. It automatically adapts to extreme input voltage fluctuations, operating seamlessly across single-phase or three-phase systems ranging from low 160V conditions up to high-voltage industrial 560V lines.
