Failure phenomenon

The copper nozzle is easily broken/damage.




Failure analysis:

During the welding process, there is heat diffusion to the copper nozzle to cause damage



Solution

Please make sure the below adjustments are correctly finished:

●Adjust the red light deviation to be center

●Adjust the Focus point
● The scanning width should be ≤5, normally we set it to be 3.

●When welding, try to weld the gun and the plate at 45°, not vertically

●Check & replace the lens (protective lens, focusing lens, reflective lens, collimating lens) if they're damage.

●High reflective materials such as aluminum plates will also cause the copper nozzle to be hot, which is uncontrollable
