How To Judge Co2 Laser Tube Quality Problem

 
(1) Laser engraving and cutting depth is not enough when the laser tube start to work
Please kindly check the laser tube installing fixture is proper or not. Light path is correct or not. Focusing distance setting is correct or not. Mirror and focus lens face is clean or not. If it has scratch, if all is ok, we judge it is the laser tube problem.
 
(2) Laser engraving and cutting depth is not enough after laser tube working a while.
Please kindly check the laser tube installing fixture is proper or not. The laser cooling water temperature is higher than 30 degree or not. The focus lens and mirror is hot or not. The volume and pressure of the cooling water is normal or not.If all is ok, we judge the laser tube have quality problem.
 
(3) High voltage spark and discharge
Please kindly check positive connector is dirty and wet or not. It is near to machine metal body or not. For laser power supply positive connector is connected or not. the high voltage cable is break or offline or not. If all is no problem, we adjust the laser tube is quality problem.
 
(4) CO2 Laser tube break off, crack, laser head fall off.
      (a)The cooling water temperature is controlled between 25-30 temperature or not. In cold area, the water cannot stay in laser tube for freezing.
      (b)The laser tube working is under laser water protective controlled or not. (Test the laser beam occur or not once the water protective stop work)
      (c)The laser tube has bubble or not.
      (d)Laser water pressure and volume is normal or not. And the direction of laser water flow in laser tube is from lower to higher point.
      (e) The water pipe is knotted or not.
If all is ok, the laser tube have quality problem, we need to replace a new co2 laser tube.
