IGBT Module Inverter Series MAX ARC 630D
Features of MMA 250 Welding Machine:
Advanced Technology and Design
The MMA 250 Welding Machine utilizes an IGBT (Insulated Gate Bipolar Transistor) full bridge inverter circuit, ensuring high efficiency, compact size, and excellent performance.
Enhanced Safety and Reliability
Equipped with multiple protection features, the machine ensures reliable operation and longevity, safeguarding against common issues like overcurrent, overvoltage, and overheating. The Voltage Reduction Device (VRD) reduces the open-circuit voltage to a safe level when not welding, enhancing user safety and preventing electric shocks.
User-Friendly and Versatile Performance
Adjustable arc start and arc force settings allow for optimal performance with various types of electrodes, ensuring smooth ignition and stable arcs for high-quality welds.A remote control feature enables current adjustment from a distance, providing convenience and flexibility for welders working in large or complex environments.
Wide Range of Applications
The MMA 250 Welding Machine works effectively with a wide range of electrodes, including acidic, alkaline, cellulose, and heat-resistant steel electrodes, making it suitable for diverse welding tasks.
Robust Performance
The machine has a strong ability to handle power supply fluctuations, with a tolerance ratio of 15% (exceeding the industrial standard of 10%), ensuring stable performance even in unstable electrical conditions.
