High-Performance 120A Single-Phase MMA Inverter with IGBT Control

The GYSMI 120A is a powerful and portable single-phase MMA inverter welder designed for professional fabrication, maintenance, and site applications. Built with advanced IGBT inverter technology, it delivers a precise welding current range of 10 to 120 amps, ensuring consistent arc stability and smooth metal fusion. The high open-circuit voltage guarantees immediate ignition, while constant current regulation provides uniform penetration and clean weld finishes. Capable of welding mild steel, stainless steel, and cast iron up to 8 mm thickness, the unit supports coated electrodes up to 3.2 mm diameter. Weighing just 2.7 kg, the GYSMI 120A combines compact design with robust performance, making it ideal for workshop or mobile use. Integrated Hot Start, Arc Force, and Anti-Sticking functions enhance usability and reduce electrode sticking. Generator compatibility and protection against voltage fluctuations (±15%) ensure reliable operation in demanding environments.
