GYS Kronos 400t Duo - No Accessories

GYS KRONOS 400T DUO – Professional Multi-Process MIG/MAG Industrial Inverter

The GYS KRONOS 400T DUO is a premium three-phase multi-process inverter welder engineered for the most demanding industrial and automotive applications. Its modular dual-wire design allows operators to connect two different wire feeders, providing seamless transitions between materials such as steel, stainless steel, aluminium, and flux-cored wire. With intelligent synergy control and an intuitive 3.5” multilingual colour interface, welders can achieve optimal parameters automatically by entering wire diameter, material type, and thickness. The Easy Mode simplifies operation for general users, while Expert Mode provides complete control for advanced welders. Offering exceptional arc stability, precise digital regulation, and a rugged IP23S-rated chassis, the KRONOS 400T DUO is built for high-duty performance in tough environments. It is ideal for bodyshops, manufacturing, and fabrication workshops that demand versatility, productivity, and superior weld quality.
