The cutting power supply consists of two parts: the main circuit and the control circuit. The electrical principle: the main circuit includes a contactor, a three-phase power transformer with high leakage resistance, a three-phase bridge rectifier, a high-frequency arcing coil and a protection component. The high-leakage resistance leads to a steep external power supply characteristic. The control circuit completes the entire cutting process through the push button switch on the torch:
Pre-ventilation - main circuit power supply - high frequency arcing - cutting process - interest arc - stop.
The power supply of the main circuit is controlled by the contactor; the short-circuit of the gas is controlled by the solenoid valve; the control circuit controls the high-frequency oscillator to ignite the arc, and stops the high-frequency operation after the arc is established.
Advanced plasma cutting technology, CNC fine Plasma Cutting Machine sales all over the world, widely used in ships, metallurgy, engineering machinery and other industries.

Plasma Cutting Machine with different working gases can cut a variety of oxygen cutting difficult to cut metal, especially for non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel) cutting effect; its main advantage is that the cutting thickness is not When the metal is large, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times of the oxygen cutting method, the cutting surface is smooth, the heat deformation is small, and there is almost no heat affected zone.
