Cutting current selection of portable plasma cutter

When using the CNC plasma cutting machine for high-quality rapid cutting, the cutting process parameters must be deeply understood and mastered. Only in this way can the maximum efficiency of the plasma cutting device be exerted and the workpieces cut will be optimal. The effect, the following is to explain the cutting current adjustment parameters of the plasma power supply when the plasma CNC cutting machine works in the cutting workpiece, for the reference of the majority of users.

When the plasma CNC cutting machine cuts the workpiece, the cutting current regulation problem of the machine plasma power supply is very important. It is the most important cutting process parameter, which directly determines the thickness and speed of the cutting, that is, the cutting ability. Regarding the impact, it is directly represented by the following selection of cutting currents for plasma CNC cutting machines:

1. The cutting current of the plasma numerical control cutting machine increases, the plasma arc energy increases, the cutting ability increases, and the cutting speed increases accordingly;

2. The cutting current of the plasma numerical control cutting machine increases, the diameter of the plasma arc increases, and the arc becomes thicker, so that the slit becomes wider;

3. The cutting current of the plasma CNC cutting machine is too large, so that the nozzle heat load is increased, the nozzle is damaged prematurely, the cutting quality is naturally reduced, and even the normal cutting cannot be performed. Therefore, the cutting current and the corresponding nozzle should be correctly selected according to the thickness of the material before cutting.
