MÁY HÀN ARC 250 (ARC 250)
Description:
Raise the frequency from 50/60Hz to high frequency, e.g.100K Hz. After reducing the voltage and rectifying, output powerful DC with the technology of PWM. The weight and size of the main transformer decrease dramatically but the efficiency will rise by over 30%.
- With the function of auto-compensation against power fluctuation. And the output welding current will be stable.
- Having the function of auto-protection against over-voltage and over-current.
- Having powerful arc-force.
- Reliable quality with small dimension and weight, but high efficciency.
- Able to weld basic and acid electrodes.
- Applicable to low carbon steel, medium carbon steel and alloy steel.
