Mosfet DC Inverter MMA Welding Machine
Models:ZX7-250
We can cooperate in many ways:OEM\ODM\OBM\regional agency and so on.
Use high power MOSFET technology, convert 50/60 frequency to high frequency (100HZ above), then reduct voltage and rectify, get high DC power output by PWM technology. Both the weight and dimension of the main transformer decrease dramatically with improved 30% efficiency.
1.With automatic compensation for voltage fluctuation, strong ability to resist the power supply fluctuation,stable output welding current;
2.Excellent thrust compensation;
3.Applicable for various kinds of welding rods such as acidity and alkalinity;
4.Automatic protection when over-voltage or over-current happens;
5.Reliable, portable, high efficiency and energy saving;
6.Applicable for welding low-carbon steel, medium-carbon steel,alloy steel, etc.
