Arc pressure adjustment is a necessary function for plasma cutting in plasma CNC cutting machine. It can be applied to any plasma CNC cutting machine. Gantry CNC cutting machine, desktop CNC cutting machine, portable CNC cutting machine will use plasma cutting. When equipped with the arc torch adjustment function of the cutting torch
When the automatic height adjustment function is turned on, the height of the cutting torch is automatically adjusted with the height of the steel plate to ensure the cutting quality. During the cutting process, maintaining a constant distance between the cutting tip and the workpiece is the key to ensuring the cutting quality. Therefore, different cutting methods also use different height adjustment systems, which can meet different cutting process requirements.
Arc pressure automatic height adjustment system: The height of the cutting torch is automatically adjusted according to the voltage of the plasma output, so the arc pressure automatic height adjustment can only be applied to the plasma cutting machine. Its working principle is that there is a certain voltage between the steel plate and the plasma electrode. By collecting the voltage signal, it is used by the arc voltage automatic height-adjusting system after being processed by the voltage division module. After comparing with the set voltage, the system will give the motor a rising or falling signal to keep the set voltage equal to the collected voltage. The motor stops working, so the automatic height adjustment function of the plasma torch is realized.
