GYS KRONOS 400T DUO – Industrial Multi-Process Inverter Welder
The GYS KRONOS 400T DUO is a high-performance, three-phase multi-process inverter welder designed for industrial MIG/MAG, TIG DC, and MMA welding applications. Its innovative modular design allows connection to a separate WF 35 wire feeder for fast switching between two different wire types or diameters — ideal for workshops handling varied materials such as steel, stainless steel, aluminium, and flux-cored wire. This machine integrates advanced digital synergy technology to automatically optimise welding parameters based on wire diameter, material type, and gas mix, ensuring consistent and high-quality welds. A 3.5” colour multilingual interface simplifies parameter control, while on-demand ventilation improves energy efficiency and lifespan. Built for professional use, the KRONOS 400T DUO delivers premium weld performance, flexibility, and reliability in demanding industrial environments.
