inverter DC MMA welding machine

The large power component MOSFET(field-effect transistor) is adopted to convert 50/60Hz industrial frequency into high frequency (100KHZ above).Then, output large power DC source by declining the voltage, rectifying the current, and through pulse-width modulation (PWM) technology. The weight and volume of the main transformer is significantly declined and the efficiency is increased by 30% above. 
 
1. Has the auto-compensation function to mains voltage fluctuation, powerful ability in anti-fluctuation of mains, welding current stable and reliable.
2. Automatic over-voltage, over-load, over-current protection function.
3. Excellent arc force compensation, easy arc- striking with arc force function.
4. Reliable quality, small volume, light-weight, high efficiency and power saving.
5. Acidic and alkaline welding rods of various brands can be used for welding.
