Maintenance and precautions of plasma cutting machine

1. Before operation, the operator must wear insulating shoes, insulating gloves and protective glasses. The equipment must be reliably grounded.

2. For the contact arc ignition method, press the button on the gun first, and then the nozzle quickly touches the edge of the cutting workpiece, which is more conducive to induced arc cutting. When arc ignition is difficult, the air pressure can be adjusted to the lower limit!

3. The pressure reducing valve and air compressor should be drained frequently. When cutting, they should not move at excessive speed to avoid slag and arc reflection caused by incomplete cutting of the workpiece. Also, the cutting speed should not be too slow to make the workpiece red hot and affect the quality of the incision. When cutting stops, release the button first, and then lift the torch. The above specifications have significantly improved the service life of the electrode nozzle.

4. When cutting, you should always pay attention to the air pressure, voltage, the use of the electrode and the nozzle. Do not spray copper after the hafnium wire in the electrode is used up, causing the electrode and the conductive tip to short-circuit and burn out the cutting gun. The hafnium wire in each electrode is about 3mm long. After the nozzle aperture is increased, the cutting quality and thickness will be seriously reduced, and the nozzle should be replaced immediately!

5. If it is found that the kerf is seriously deviated, check whether the nozzle nozzle has been deflected. Otherwise, the nozzle and electrode should be replaced. It is worth noting that the roughness of the cutting surface is related to the surface of the cutting plate; if the surface of the plate is rough and unclean, and the cutting movement is uneven, the incision will be large and the surface quality will be seriously degraded.

6. The service life of electrodes and nozzles is related to the thickness of the plate and the operation technology. Under normal circumstances, each electrode can be used continuously for about 1 hour.

      

Care and Maintenance

1. Do not use and store the cutting machine in strong sunlight;

2. Do not use or store the cutting machine in a humid environment;

3. When the cutting machine is in use, keep its ventilation holes unobstructed;

4. The cutting machine should be used in a well-ventilated environment,
