IGBT Stamos Germany MMA 250A inverter welder

Manufacturer name: S-MMA 250.IGBT

The S-MMA 250.IGBT inverter welder is designed for welding metal materials both indoors and outdoors. This is made possible by the MMA method, which does not need shielding gas. It uses covered electrodes suitable for welding steel, iron, aluminum, copper or nickel up to 10 mm thick.

Modern IGBT inverter technology guarantees stable and precise operation. It also influences the high reliability of the device, as it uses three-pin semiconductor elements that prevent short circuits.

Product features:

• - Practicality - it is suitable for processing parts made of steel, iron, aluminum or copper, among others,
• - Efficiency - use of modern IGBT technology guarantees precise operation and safety against short circuits,
• - Intuitiveness - easy-to-use control panel and stepless knob allow precise setting of welding current value,
• - Mobility - comfortable handle and small size make it easy to carry the welder,
• - Safety - an overheat protection system and a hot air exhaust fan protect the device,
