1. Check the cleanliness of protective lenses: please clean them in time if they are not clean; If there is a burning point that affects the use, please replace it in time, "the lens with a burning point cannot be used on the opposite side, and the burning point will magnify and produce a smoking effect when contacting the light source, affecting the quality of the focusing lens". (pay attention to ensure that there is no dust on site when the protective mirror drawer is taken out, and effectively seal the protective mirror window with masking paper in time).
2. The cutting nozzle should ensure the coaxiality of the laser head. If the nozzle mouth is irregular and there are obvious scars, it is recommended to replace it in time. Avoid coaxial deviation or wrong air flow affecting the cutting effect for this reason.
3. The ceramic ring is the conductive part of the follow-up system. Pay attention to looseness, impact and cracking in use to improve the stability of the cutting operation of the equipment.
4. Always pay attention to the gas margin to avoid burning the cutting head without gas cutting.
