Attentions when using plasma cutting machine

Attentions when using plasma cutting machine:

1. During the using of the plasma cutting machine, the flow rate of the air compressor should be higher than 0.3 cubic meters per minute, and its working pressure range is between 0.4 and 0.8 MPa.

2. When cutting the metal plate by arc starting, the arc should be started from the edge position of the workpiece.

If you want to cut from the middle position of the board, you need to drill a small hole first in the middle position, and then start the arc from the edge position of the small hole.

3. Before cutting, the power switch should be turned on for a period of time to allow air flow to circulate for a period of time so that the condensed water vapor in the torch can be removed.

4. In the cutting process of cnc plasma cutting machine, the cnc plasma cutting speed must be appropriate, so that it can cut through the metal plate workpiece.

If the speed is set too fast, the nozzle will be burned by anti-slag; if it's too slow, it will easily reduce the lifespan of the nozzle, and there may be more slag because the slit becomes wider and the arc breaks.

5. In the cutting process of cnc plasma cutting machine, the motor and nozzle of plasma cutter must be checked frequently. If it is found that the wear is serious, it should be replaced in time.

6. When the metal plate stop cutting, release the torch first, and then let the torch leave the processed metal plate.
