„ Lasing quality
Troubles
There is a decrease in
laser processing quality.
Lasing does not work
partially.
Drawing line runs over
the intended start or end
points.
160
Causes
Laser emission port is not clean.
Fumes occurring during lasing hinder
laser beam.
Distance to object is not appropriate.
Lasing surface of object is inclined.
There are variations in properties of
objects.
• Thickness varies.
• Surface roughness varies (including
those in gloss).
• Material varies (including those in
chemical composition).
Object feeder is not stable.
Performance of laser oscillator
deteriorates due to aging.
Obstacle hinders laser beam.
Laser emission port is not clean.
The setting in lasing quality parameters
does not match the other settings.

Measures
Refer to the "Maintenance" in Setup/Maintenance
Guide and clean contaminants off the laser
emission port.
If contaminants persist, replace laser emission
port protective glass.
Contact our sales office.
• Install dust collector.
• Check that dust collector works well.
Adjust distance between bottom surface of laser
welding machine head and lasing surface of
object.
Make adjustment so that bottom surface of laser
welding machine head and lasing surface of
object are parallel with each other.
Adjust the setting parameters and work distance
according to respective target objects.
Adjust object feeder so that position of objects
become stable.
• Increase setting value of laser power.
• Decrease scanning speed.
If it is not possible to get the same laser
processing quality as before even with the max.
value of the laser power setting, laser oscillator
must be replaced. Contact our sales office.
Remove obstacle between laser emission port of
laser welding machine head and object.
Refer to the "Maintenance" in Setup/Maintenance
Guide and clean contaminants off the laser
emission port.
If contaminants persist, replace laser emission
port protective glass.
Contact our sales office.
Adjustment the lasing quality parameters such as
laser starting, laser ending, or wait value in file
option menu.
