Gysmi 100a (colour Box)
Compact 100A Single-Phase MMA Inverter with IGBT Technology
The GYSMI 100A is a single-phase MMA inverter welder engineered for professional and maintenance applications requiring portability and consistent arc performance. Built using advanced IGBT inverter technology, it delivers a welding current range of 10 to 100 amps, providing smooth, stable output and excellent ignition characteristics. The high open-circuit voltage ensures immediate arc striking, while constant current control guarantees uniform fusion and strong penetration on mild steel, stainless steel, and cast iron up to 5 mm thick. Designed with mobility in mind, the unit weighs just 2 kg and features a compact housing with an integrated carry strap. Generator compatibility and protection against overcurrent and voltage fluctuations (±15%) make it ideal for on-site operations. With integrated Hot Start, Arc Force, and Anti-Sticking functions, the GYSMI 100A ensures reliable performance and professional weld quality in a highly portable format.
