Mma 250 Gt (555-gt) Welding Machine
The MMA 250 GT (555-GT) is a professional industrial welding machine designed for heavy-duty applications. Built with an advanced IGBT digital inverter board, it delivers stable, precise, and efficient welding performance while remaining portable and user-friendly. The large LED display allows easy monitoring of welding parameters, electrode size, and function modes, even without removing the welding mask, making it ideal for workshop and field use.
This machine supports multi-process welding, including MMA (Stick) and TIG Lift, and comes with essential functions like Hot Start, Arc Force, Anti-Stick, and VRD. These features ensure smooth arc striking, prevent electrode sticking, and allow adjustments for various welding conditions. It is compatible with rutile and alkaline electrodes, as well as 6010, 6011, 6013, and 7018 rods, making it versatile for industrial and construction applications.
Safety and reliability are key strengths of the MMA 250 GT. The MCU-controlled system and digital IGBT inverter technology regulate the welding process, maintain consistent arc stability, and automatically compensate for voltage fluctuations. Built-in protections against over-current, overload, and high temperature ensure secure and dependable operation in demanding environments.
Technical Specifications: The MMA 250 GT operates on AC 220V 15% and 50/60 Hz frequency, with a rated input current of 58.4 A. It has a no-load voltage of 59 V, output current range of 30250 A, and a rated output voltage of 28 V. The machine offers a 60% duty cycle, 40 W no-load loss, 80% efficiency, power factor of 0.73, insulation grade F, and protection class IP21.
