Harmful gases and vapors
The device is equipped only with a simple air filter
and a fan to extract welding gases and fumes from
the working chamber. The air filter consisting of a
spark protection mat and a filter fabric
(

REPLACING THE AIR FILTER).
When working with metals or metal alloys that may
release harmful substances when heated or
vaporized, an external extraction and filter unit must
be connected.
Noises
The continuous sound level produced by the device
is always less than 60 dB(A).
Specific safety information
Normal welding mode
The following instructions must be observed during
proper use of the device (if your hands are in the
working chamber):
•
When positioning the workpiece, always make
sure that both arms are firmly lying in the rings
of the hand openings. This allows you reliably
and calmly move the workpiece into the correct
position for welding.
•
Fingers and hands may not be positioned near
the laser beam due to the burn hazard. This
area is identified by cross-hairs when you
watch through the microscope.
•
Do not wear shiny jewelry (rings, watches, bra-
celets). Depending on their surface properties,
they may focus the scattered radiation and thus
cause slight skin burns. Leakage radiation that
is emitted by the welded material can also cau-
se small burns on the surface of the hand under
certain unfavorable circumstances.
•
Be calm and concentrate when triggering laser
pulses.
•
For subsequent pulses, always use the micros-
cope to check that the workpiece is positioned
correctly.
What to do if you receive a bum
If you suspect that you have been burned your eyes,
immediately notify the laser safety supervisor or the
safety expert, and consult a doctor if necessary.
If you receive a burn from a laser pulse on your
finger or hand, treat the wound (obtain medical
assistance if the burn is strong enough). Although a
small burn is not particularly critical, you should still
make sure that no infection results.
Handling deionised water (cooling water)
In the inner cooling circuit of the laser, twice-distilled
and deionised water is used as coolant.
When using this water, do not let it contact your skin
and especially the mucous membrane of the eyes,
nose and mouth.
Immediately dry the wet spots on your skin with a
clean cloth or flush the wetted mucous membrane
with tap water.
Serving and maintenance
General instructions
•
Any one operating, servicing and repairing the
laser device must have read and understood
the safety instructions in this instruction hand-
book.
•
Check for loose screw connections and tighten
them after reinstalling.
•
After servicing is finished, the operation of all
safety devices must be checked.
Tasks that can be performed by the opera-
tor
The operator may only perform service and mainte-
nance tasks that are described in this instruction
handbook.
When doing these tasks,
•
always pull the power plug
and
•
observe the special safety instructions in the
corresponding sections.
