How to adjust the current of CNC Plasma Cutting Machine

How to adjust the current of CNC Plasma Cutting Machine

 

In the process of using CNC plasma cutting machine, it is very important to adjust the current of the machine to use the plasma power supply to cut the cutting quality of the workpiece in the actual cutting process. The thickness of the pass, the corresponding current adjustment, only the skilled current Only by adjusting the operation can the plasma cutting machine be used correctly to achieve the cutting effect. As a professional engaged in the research and development of CNC cutting machines, I have summarized the selection of cutting current adjustment parameters of the machine plasma power supply for plasma CNC cutting machines when working on cutting workpieces for many years.
When the plasma CNC cutting machine is cutting the workpiece, it is very important for the adjustment of the cutting current of the machine plasma power supply. It is an important cutting process parameter, which directly determines the cutting thickness and speed, that is, the cutting capacity. Regarding the impact, it is directly expressed as the following forms of selection of the cutting current of the plasma CNC cutting machine:
1. The increase of the cutting current of the plasma CNC cutting machine, the plasma arc energy increases, the cutting capacity increases, and the cutting speed increases accordingly;
2. The cutting current of the plasma CNC cutting machine increases, the diameter of the plasma arc increases, and the arc becomes thicker, making the cut wider;
3. Excessive cutting current of the plasma CNC cutting machine increases the thermal load of the nozzle, the nozzle is prematurely damaged, and the cutting quality naturally declines, and even 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.
