All size CO2 laser tube 20W~180W laser cutter

A, Engraved is not deep:

1. The laser can light but not deep engraved: check the supporting point of the laser tube is reasonable or not, whether the light intensity is set too small, whether the optical path shift, whether the focal length is correct, whether ytterbium sheet surface scratches and dirt, whether the flow of cooling water's flow pressure normal, if no problem with the above checks, then check  whether there are scratches and dirt inside the laser's lens light outlet pipe, if normal, then it is the quality of the laser tube's problem.

2. Emitting the light for a while before the engraved is not deep: 

For this problem, first check the supporting point of the laser tube is reasonable, whether the water temperature exceeds 30 degrees, the lens is heat at work, whether the flow of cooling water flow pressure is normal, if the cooling water clean, above normal then check the laser tube.

 

B, the high voltage ignition and discharge:

1. Check if there is any dirt and moisture at the around of high voltage cap, if its too close from the metal parts of the machine; 

the other is a laser high-voltage power supply connecting device is fell off,  whether internal high-voltage connection device disconnection or destruction. 

If above normal, then it is the laser tube's quality issue.

 

C, the laser tube broken, cracked, water cooling head off:

1. Whether the water is controlled in the range of 25 ℃ -30 ℃, the cooling water can not freeze in cold regions, especially after laser shutdown, may not allow the cooling water retention in the laser tube.

2. Whether luminous work under the protection of water control; (test whether light can emit with the water's on-off or not)

3. Check the water pipes have folded or not.

4. Whether there will be bubbles within the laser tube.

5. Check whether the water pressure is normal; whether the flow directions is correct or not.

6. If 1-5 terms are all clear, then it the laser tube's quality issue.
