INSTALLATION
4-1 UNPACKING
All components of the stereo microscope are carefully packed, ensuring delivery in an
immaculate condition. We recommend to keep the packaging material, as it is used for
sending in the microscope or storing it for a longer period of time or transporting it to a
technical service team.
The MEZZO packaging contains the following components:
Microscope head with mount and LCD glare protection filter (4.2 Fig.1 - 10)
Two eyepieces with eyepiece covers (4.2 Fig. 2 - 1)
Supporting arm (for holding the welding hand-piece), with integrated LED light (4.2
Fig.12)
Bearing rod (4.2 Fig.1 -11)
Base plate, for attaching the bearing rod (4.2 Fig.1 -13)
Protective cover
Tools for adjusting the focussing levels
Remove and handle all microscope components with great care.
Avoid touching the lenses and optical elements. Also avoid contact with dust, water and
other polluting substances, as they soil or damage the lense surfaces and influence the
quality of the view.
ASSEMBLY AND START-UP
Please perform all work stages involved with the assembly of the stereo
microscope very carefully. The stereo microscope’s individual parts and elements
should not be assembled too forcefully.
Mount the bearing rod (11) to the base plate (13) with the attachment screw and place it
upright onto an even, safe and clean surface
Slide the supporting arm (12) over the bearing rod (11) and secure it slightly above the
middle of the rod, tightening hand tight.
Slide the microscope head (8) and its mount with retaining screw (9) over the bearing rod
(11), and secure it at about 5cm above the supporting arm for the hand-piece (12).
Insert eyepieces (1) and eyepiece covers and secure with locking screw (4)
Connect the control line (15) to the eye protection filter (shutter) (6) with the welding
device (note welding device instructions!)
Connect the LED light with the PUK 3s .
Insert the mains cable (16) into the connection socket marked “LED-Lamp 800 mA”, on
the back of the welding device.
Note!
Always test that the eye protection system (shutter) is in correct functioning order
before you start welding.
Through a press on the output power regulator of the welding device "PUK 3s",
you switch the eye protection filter from bright to dark.
If the eye protection filter (Shutter) does not switch from bright to dark, it must
immediately be replaced.
