Commonly used plasma arc task gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some of the inclusion gases.
CNC Plasma cutting machine is widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structure and other lines of plasma cutting machine mainly used in metal plate cutting, including some use of other equipment can not be cut in the situation, can be used for various types of metal materials, including stainless steel, alloy steel, carbon steels, copper and other nonferrous metals. The machine can be based on the requirements of cutting plates into a complex shape. Its characteristics: Unchanged, reliable, simple, energy-saving, no noise, cutting speed, cutting the mouth light, no grinding. The operation method is as follows: Turn the power switch, so that the power switch is placed on "on" status. At this point, the blower starts to twist, the table Head screen displays the set current value. Regulate the pressure of the knob to the required pressures, open the tight air valve. Press the control button on the cutting gun, solenoid valve action, the machine could hear high-frequency arc discharge sound, also cutting gun nozzle should have gas outflow, cutting gun nozzles have plasma arc spray out. The cutting current of the response is set according to the thickness of the workpiece. Will cut the gun copper nozzle and workpiece spacing 2mm, press the cutting gun button to ignite the arc, the high frequency arc sparks immediately disappear, at this time can start cutting.
CNC plasma Cutting Machine Common divergent task gases can cut all kinds of oxygen cutting hard to cut metal, especially about nonferrous metals (stainless steel, aluminum, copper, titanium, nickel, cutting results are better; Its primary strengths lie in cutting the thickness of the metal of cent, plasma cutting speed, especially in the cutting of popular carbon steel sheet, speed can reach oxygen cutting method 5~6 times, cutting surface brightness, heat distortion small, there is no hot impact zone!
CNC plasma Cutting machine to launch 2012, the task of gas (the task gas is plasma arc conductive medium, and also carry heat, also to remove the cut of molten metal) plasma arc cutting characteristics and cutting quality, speed has a distinct impact.
