What are the tips for using a CNC plasma cutting machine?

1. Start cutting from the edge: It is recommended to start cutting from the edge of the workpiece instead of perforating. This method can extend the service life of consumables. The correct operation is to start the plasma arc after the nozzle is directly aimed at the edge of the workpiece.
2. Reduce the "arcing" time: When the arc is started, the nozzle and electrode wear faster. Therefore, make sure that the cutting torch is close to the cutting metal before starting.
3. Avoid overloading the nozzle: Overloading the nozzle will quickly damage it. Make sure that the current intensity does not exceed 95% of the working current of the nozzle.
4. Use a suitable cutting distance: According to the instructions, select a suitable cutting distance, that is, the distance between the cutting nozzle and the surface of the workpiece. When perforating, you can use a distance twice the normal cutting distance or the maximum height that the plasma arc can pass.
5. Reasonable perforation thickness: Make sure that the perforation thickness does not exceed the range allowed by the system. Usually, the perforation thickness is 1/2 of the normal cutting thickness.
