Industrial 330Amp IGBT Dual Module Inverter ARC/MMA Welding Machine - China Suppliers and Factory Direct Offer
ARC-ECONOMIC are manual inverter welder series which is made by international most advantaged invert technical. Inverter MMA welding power supply is inverter arcwelding machine which is sprung up in 1980s in international market. 50Hz/60Hz frequency is inverted to high frequency (frequency is over 100KHz) by MOSFET, then step down voltage and rectificate current. Inverter arc welding power supply generates powerful DC welding current through PWM technical. Because inverter technical of switch power is used, dimensions and weight of welding machine has reduced substantially and efficiency has increased 30%. Stabilizing, reliability, lightness, save-energy and no electromagnetic noise are characteristics of welding machine series. Inverter welding machine is developed that is given praise of revolution of welding field by specialist.
The welding machine obtains the 220V power frequency alternating current through switch sw101, after the inductance coil filter for the single plane rectification bridge MDQ3504*2 rectification, and has the electric capacity C1-C4 filter to turn the direct current, by way of the IGBT/MOS composition bridge type invertor inversion existing agreement is the 20KHZ alternating current, passing through the intermediate frequency transformer TI live pressure, and restores the diode DK 1-DK6 rectification quickly, at last filters by the output reactor L101 and outputs steadily the direct-current power supply for the welding.
- All movements adopt the latest and mature IGBT full-bridge inverter technology.
- With thermal arc starting function, arc starting is more efficient.
- Dual IGBT module, reliable operation performance.
- Acid/alkaline electrodes, stainless steel electrodes for stable welding.
- Complete undervoltage, overcurrent, overheating and other protection functions, safe and secure.
- The thrust current is continuously adjustable, effectively solving the problems of sticking welding rod and arc interruption.
- Accurate digital display current preset, easy and intuitive operation.
- Standard three-proof design, suitable for various conventional harsh environments, simple and convenient to operate.
