Raise the frequency from 50/60 HZ to high frequency e.g. 100Khz. After reducing the voltage and rectifying output powerful DC with the technology of PWM. The weight and size of the main transformer decreases dramatically but the efficiency will rise by over 30%.
1. With the function of auto-compensation against power fluctuation and the output welding current will be stable.
2. Having the function of auto-protection against over-voltage and over-current.
3. Having powerful arc-force.
4. Reliable quality with small dimension and weight as well as high efficiency.
5. Able to weld basic and acid electrodes .
6. Applicable to low carbon steel, medium carbon steel and alloy steel.
