2.6.5 Risk of optical system
2.6.5.1 Routine operation
The reflector of the optical system adopts glass as reflector medium, and the focus lens of
the marking head is made of selenium zinc material. In normal condition, these optical parts are
free of danger.
However, polluted focus or focus with damaged coating will cause thermal reducing by laser
beam over 400℃, the xic smoke is generated. At this time, the laser device must be powered off,
mechanical movement must be stopped and blowing air to the lens. At this moment, cleaning
and parts replacement should be performed after the dust subsiding please do not raise dust.
Attention
 During laser cutting, the smoke generated may be very toxic. The smoke is
removed by upper exhaust blower system;
 Cutting with abnormal blower system is prohibited.
Note
 Make frequent check on the ventilation system;
 Clean and maintenance the blowing system regularly;
 Foreign matter coming into duct of the blowing system is strictly prohibited;
 Ensure a good ventilation and the exhaust gas expel from the working room;
 Ensure a necessary disposal of the exhaust gas to satisfy emission requirements
prescribed by the state and local government
Note
 During cleaning, please wear on goggle and gloves. The damaged parts must be sealed in a
container and properly packaged, and then returned to the manufacturer.
 Good ventilation is required in case of any damage of the parts.
