LaserStar T Plus
Maintenance (care)
The maintenance of the device reduces to the
cleaning of the surfaces with a damp cloth with light
alkaline solution.
Maintenance
Maintenance intervals
Monthly maintenance
or if welding results are unsatisfactory or after each
lamp replacement.
Test the laser energy with trial shots. If the results
are unsatisfactory:
• Check the laser setting including the pulse sha-
pe option.
• Check and clean the lens protective glass (
→
section REPLACING THE LENS PROTEC-
TIVE GLASS).
• If the shot image is round, increase the kW set-
ting. If the output must be increased by more
than 20 %, change the lamp (
→ section
REPLACING THE LASER FLASH LAMP).
When satisfactory results cannot be obtained by the
above measures, contact the service department.
Half-yearly maintenance
• Check the water level in the tank (
→ section
CHECKING/REFILLING THE COOLANT).
• Clean the heat exchanger blades (
→ section
CLEANING THE HEAT EXCHANGER
BLADES).
Maintenance after 2000 operating hours or at least
every year
• Replace the DI water filter (
→ section REPLA-
CING THE WATER FILTER AND THE DI
WATER) and change the deionised water.
• Check safety equipment (see homonymous
section).
By no means use strong cleaning agents (e.g.
cleaning powder) or solvents!
All maintenance work not explicitly
described in this manual may only be
carried out by specially trained and
authorized service engineers - even
when the laser is switched off.
Daily maintenance
or after strongly splashing welding
• Check the protective glass in front of the lens
at least once a day and, if necessary, clean it
with lens-cleaning paper (e. g. KODAK lens
cleaning paper or Kleenex) soaked in a sol-
vent (propyl alcohol).
• If major metal splashes stay adherent, the pro-
tective glass has to be replaced by a new one.
If you don't do this, there is a risk of the glass
being overheated at those points and possibly
cracking, thus causing injury or destroying the
lens (
→ section REPLACING THE LENS
PROTECTIVE GLASS).
Weekly maintenance
• The splash protection window should be che-
cked at least once a week for scratches,
cracks or holes. If the view of the working
chamber is impaired, the splash protection
window should be replaced or cleaned (
→ sec-
tion REPLACING THE SPLASH PROTEC-
TION WINDOW).
• Check the leather cuffs and the leather cloths
in the hand openings for signs of wear.
Uncontrolled escape of laser
radiation!
If there are holes in the leather cuffs or
the leather cuffs do not fit tight on the
arms they must be replaced.
