A plasma cutter uses this energy to your advantage. It has a nozzle with two gas passages and a center electrode negative. If cut close with power and space charge on the metal creates a very hot spark. A gas such as argon result of the disclosure surrounding the arc is extremely hot, the molecules move at a rapid pace, meet each other and release large amounts of energy. , Contain the unpredictable arc in a smaller limit, a second round of the protection of the gas stream. The plasma is cut at an incredible 30 000 degrees to - location, something. You can cut through sheet metal as thick as butter.


In addition,
plasma cutting machine  power supply typically includes: a main inverter circuit, the electric energy supplies in an arc on the plasma-plasma torch, and ignite with a constant power supply, DC-loop, a circuit for generating high frequency superimposed on a high voltage to a pilot arc between the electrode and nozzle of the plasma torch in the output voltage of the main circuit, a circuit that the output voltage of the main circuit between the electrode and nozzle, during the pilot-arc ignition and then makes the phase of the application of the output voltage between the electrode and the work piece so the pilot to make an arc main arc and a power control unit to the main switch, the circuit of circuits with high frequency and the pilot controlling the pilot arc, rotate and subsequently maintain the central arch supports. Understand that the CNC plasma cutter Power Device that these elements are usually contained in a single chassis contains. Although the main arc power is supplied by this type of equipment for plasma cutting power depends on the type of material being cut and thickness, etc., can reach a high value, as several hundred amperes. It is therefore necessary to create a circuit with high output capacity.
