When the fiber laser marking machine is not working.

The power supply of the marking machine and computer should cut off.

Cover the field lens to prevent dust from polluting the optical lens.

In case of any fault of fiber laser marking machine, the power supply shall  cut off immediately.

If the equipment use for a long time, the dust in the air will  absorb on the surface of the lower end of the focusing lens,

which will reduce the power of the laser and affect the marking effect.

In serious cases, the optical lens will  overheated and burst. When the marking effect is poor, the focus lens surface should  carefully check for contamination.

If the surface of the focusing lens is contaminate, remove the focusing lens and clean its lower surface.

Take special care when removing the focus lens, and be careful not to damage or fall.At the same time,

do not touch the lens with hands or other objects.

The cleaning method is to mix anhydrous ethanol (analytical pure) and ether (analytically pure) in the ratio of 3:1 and use long fiber cotton swab or lens paper to invade the 8 mixture, and gently scrub the lower surface of the focusing lens.

The cotton swab or lens paper must be replaced once every side is rubbed.

During the operation of fiber laser marking machine, do not move the marking machine to avoid damaging the machine.Do not cover piles or other objects on the fiber laser marking machine .
