These conditions are encountered when welding: The light is strong at first, and slowly weakens/weakens, resulting in the inability to fuse or sparks at the copper nozzle
Cause analysis:
Usually for welding gun lens damage, including but not limited to protective lenses, focusing, collimation, reflection. This can occur due to any one or more of these damages
Replace the protective lens and look at the focus, then check the reflection and collimation, and replace the damaged lens
In addition, check whether the laser fiber head part is dirty or damaged
Analysis of lens damage:
1. Classification of damage: the motor swings abnormally caused by interference, or the red light is too biased and not adjusted, and the sealing ring will be burned out together under normal circumstances
2. Convex surface damage of lenses: generally common in pollution, such as unprotected when replaced, the form is dotted black spots
3. Plane damage of the lens: due to laser diffuse reflection, most of them are caused by reflection, forming a focus on the lens, burning the coating, and the form is white spots. The convex surface also has this morphology, and the formation principle is the same.
Troubleshooting :
To replace the damaged lenses, please check the replacement plan in the structural installation.
How to avoid it later:
In handheld welding, the most frequent replacement is related to lenses, and preventive measures are taken against the cause of damage.
1. Use original lenses
2. Pay attention to anti-pollution when replacing
3. Try not to weld vertically, especially when welding highly reflective materials
4. Protective mirror damage: preventive measures
5. Replace the damaged protective mirror in time
