Problems to be aware of when using a plasma cutting machine

1. In the process of using a plasma cutting machine, the flow rate of the air compressor used should be greater than 0.3 cubic meters per minute, and the working pressure range is between 0.4 and 0.8 MPa.

2. When cutting the plate with the arc starting, the arc starting should be started from the edge position of the workpiece. If you want to cut from the middle of the board, you need to drill a small hole in the middle position and then start the arc from the edge of the hole.

3. Before cutting, first turn on the power switch for a period of time, let the air flow flow for a period of time, so that the condensed water vapor in the torch can be removed.

4. In the process of cutting the plate with a plasma cutting machine, the cutting speed must be suitable, so that the speed of cutting the workpiece can be. If the speed is set too fast, the nozzle will be burned by the anti-slag. If it is too slow, the service life of the nozzle will be lowered. It may be because the slit becomes wider and there are more residual slag, which may cause arcing.

5. In the process of cutting the board, it is necessary to check the motor and nozzle of the mechanical equipment frequently. If the loss is found to be serious, it should be replaced in time.

6. When the sheet stops cutting, first loosen the torch switch and then let the torch leave the processed sheet.
