The cutting process

The process of cutting with plasma is an electical reaction, so that, unlike other techniques cutting, plasma cutting-cutting can only materials that conduct electricity. If a job file is started, the machine moves to forcibly open the first or cut position and the torch moves down in the direction of the material. At the end of the torch is a device, a so-called resistive sensor. Once the sensor makes ohmic contact with the surface of the material. It closes an electrical circuit, informing the machine that it has reached the surfaceof the material. The torch then lifts of the material on the amount forcibly open. The amount of open violence is higher than the cutting height to prevent pig iron from shooting directly back into the torch during the process forcibly open.

Once the force open is completed, the torch moves on the reduced amount and begins to cut the amount optinum forcibly open, cut height, and all are feeding on the basis of consumer goods and materials be cut. On plasma cutting sophisticated system, all these parameters are automatically adjusted.



Once the cutting begins, the distance between the torch and the upper end of the materials is maintained by reading the voltage from the plasma arc, in a process known as automatic torch height. Generally sheet material is not totally flat, especially thin-gauge material. To ensure a quality cut. It is important, a constant distance between the torch and the surface. Maintaining a constant level requires a response ATHC system. On some systems, you are in power is a rate of 500 times per second, and the reading used to the 2-axis up or down. The result is a quality cut, that does not require user intervention.
