Industrial 330Amp IGBT Dual Module Inverter ARC/MMA Welding Machine - High Performance from China Suppliers and Factory
Detailed Information
ARC-ECONOMIC are manual inverter welder series which is made by international most advantaged invert technical. Inverter MMA welding power supply is inverter arcwelding ma-chine which is sprung up in 1980s in international market 50Hz/60Hz frequency is inverted to high fre-quency (frequency is over 100KHz) by MOSFET, thcn step down voltage and rectificate current in-verter are welding power supply generates powerful DC welding curent through PWM technical. Because inverter technical of switch power is used, dimensions and weight of welding machine has re-duced substantially and efficiency has increased 30%. Stabilizing. reliability, lightness, save-energy and no electromagnetic noise are characleristics of weldine 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, af-ter 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 existinp agreement is the 20KHZ altemating current, passing through the inter-mediate frequency Iransformer 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.
