China Suppliers Factory Portable 400A ARC/MMA Welding Machine with Dual Module IGBT Inverter 300AMP Performance
Detailed Information
The MMA series arc welding machine is not only portable but also saves energy. It introduced the advanced IGBT/MOS (insulated gate bipolar transistor) and fast recovery diode as the main parts of controlling and delivering. IGBT/MOS can change 50Hz or 60Hz to 20KHz. Because the electric current can regulate, the arc electric current obtains excellent welding craft adaptability. It features superheat, overpressure, and automatic protection functions. The technique of the MMA inverter welder compared with the traditional technique has the advantage of saving energy, being lighter weight, and having a superior structural design. Perfect for outdoor decoration and fieldwork, it mainly welds low carbon steel, stainless steel, metal alloy steel, cast iron, etc. Because of the appropriate control of the lead arc electric circuit, it welds with high efficiency and stability.
ARC-ECONOMIC is a manual inverter welder series made using the world's most advanced inverter technology. Inverter MMA welding power supply is an inverter arc welding machine that emerged in the 1980s in the international market. The 50Hz/60Hz frequency is inverted to high frequency (over 100KHz) by MOSFET, then steps down voltage and rectifies current. The inverter arc welding power supply generates powerful DC welding current through PWM technology. Because the inverter technology of switch power is used, the dimensions and weight of the welding machine have reduced substantially, and efficiency has increased by 30%. Stability, reliability, lightness, energy-saving, and low electromagnetic noise are the key characteristics of this welding machine series. The inverter welding machine is highly praised by specialists as a revolution in the welding field.
The welding machine obtains the 220V power frequency alternating current through switch SW101. After passing the inductance coil filter for the single plane rectification bridge MDQ3504*2 rectification, it uses the electric capacity C1-C4 filter to turn the direct current. By way of the IGBT/MOS composition bridge type inverter, the current is converted to a 20KHz alternating current, passing through the intermediate frequency transformer T1 live pressure, and restores the diode DK1-DK6 rectification quickly. At last, it filters through the output reactor L101 and outputs a steady direct-current power supply for optimal welding performance.
