German Technology    |    Made in China 

      When the pre-igniting circuit shut off, the pre-igniting shut-off protection circuit takes into 

function and sends out the fault signal.  

      When the water flow is low in the cooling system, the water flow relay breaks and shuts off 

the pre-igniting circuit and the main power supply, thus to stop the system.  

 

C. Optical System 
 

1. Binocular microscope  
To observe the working piece clearly, the binocular large caliber and long focus length 
microscope has been used in this system. Before the object lens, there is a coated protection    
glass to protect the lens from the spatter during the laser processing. The ocular can be taken 
down by loosen the fixing bolt for the shipping and maintenance purpose.  
 
2. Laser beam expander and the focusing system 
To ensure the laser welding spot in the center of the view all the time during the focusing, the 
laser beam has to be co-axial with the beam path of the microscope. In this system, the laser 
beam and the optical path of the microscope share the same object lens. The offset of the focus  
point is adjusted by the up and down keys. The offset of the focus point is determined by the 
experiment according to the welding processing technology. 
 
3. The indication of the welding spot 

 

 

Because  the  YAG  laser  is  invisible  infrared  ray  of  1.06

m,  there  is  a  cross  in  the  ocular,  whose 

intersection  accords  to  the  laser  spot,  to  indicate  the  laser  position.  Thus  the  laser  beam  can  be 
aimed at the welding position on the piece to be welded easily. 

 

4. Cautions 

(1) It is forbidden to touch the surface of the optics by hand or scratch by something hard. It is 
also forbidden to blow the dusts on optics by mouth. It can be blown by the special blowing ball 
or cleaned by the long fiber absorbent cotton ball or the lens paper, if the optics is stained.  
(2) Normally, don’t disassemble the optical system to prevent from the damage and the dust.  
(3) Move the tube of the object lens carefully and don’t touch the protect glass. Before 
changing the protect glass, remove the front tube of the object lens first and the press ring 
carefully.  

 

D. Control System 
 

The system can be controlled by the operation panel before using, or by joystick inside the 

welding chamber during using.  

 

E. Cooling System 
 

1. Construction 
  The cooling system is the main part of the laser system. It is composed of the heat exchanger, 

magnetic pump, filter, water tank, switch of water flow, the temperature contactor, ABS hose 
and valves to form a closed circulation water system.
