One week of knowledge time is coming. (≧▽≦) Here we go...

On the use of cutting machine, we need to pay attention something.

1. In the process of using plasma cutting machine, the flow rate of air compressor should be greater than 0.3 cubic meters per minute, 

and its working pressure range is between 0.4 and 0.8 MPa.

2. When using striking arc to cut the plate, it should start from the edge of the workpiece.

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

3. Before cutting, turn on the power switch for a period of time to let the air flow for a period of time,

So that the condensed water vapor in the cutting torch can be removed.

4. In the process of using plasma cutting machine to cut the plate, the cutting speed must be appropriate to cut through the workpiece.

If the speed is set too fast, it is easy for the nozzle to be burnt by the reverse slag. 

If the speed is set too slow, it is easy to reduce the service life of the nozzle. In addition, it is possible to break the arc because the slit becomes wider and there is more slag left.

5. In the process of plate cutting, the motor and nozzle of mechanical equipment must be checked frequently. 

If the loss is serious, it should be replaced in time.

6. When the plate stops cutting, first release the switch of the cutting torch, 

and then let the cutting torch leave the processed plate.
