Measures to Re-
duce Contamina-
tion of the Optics
Crossjet and Extraction
1.
Please observe the values for the crossjet and extraction specified in these Operating
Instructions.
2.
Switch on the crossjet and extraction at least five seconds before the start of welding.
3.
Do not switch off the crossjet and extraction until the laser welding head is safely in
the smoke-free zone.
Protective Glass (including Replacement)
IMPORTANT!
Before changing the protective glass drawer, clean the area around it with
a cleaning cloth.
The environment must be clean when the protective glass drawer is being replaced.
4.
To prevent dust from penetrating the focusing lens, the laser welding head must be
vertical when the protective glass is being changed (welding torch pointing toward the
floor).
5.
Before changing the protective glass:
–
Switch on the extraction and crossjet
–
Clean the welding head with compressed air as best as you can
IMPORTANT
Do not blast the protective glass with the air current directly.
–
Switch off crossjet
–
Replace protective glass
IMPORTANT
When replacing the protective glass, the extraction must be
switched on and crossjet switched off.
6.
Keep the amount of time the protective glass drawer is open to the minimum neces-
sary.
7.
If there are welding fumes on the protective glass, replace the protective glass with a
new pane of glass.
The contaminated protective glass can be used again:
–
Pre-clean the protective glass with a cloth
–
Finish cleaning the protective glass with a cotton swab soaked in methanol
–
Store the protective glass in a dust-free area
8.
If there is welding spatter on the protective glass, the protective glass must be re-
placed with a new pane of glass immediately.
Dispose of the protective glass that has welding spatter.
9.
Check the protective glass from time to time at the start of production in order to de-
termine a change interval specific to the application.
