SECTION 1 – GENERAL APPLICATION
Proper Use of the PUK Microscope includes:
•Observation of welding processes through the Microscope Shutter and workspace lighting.
•The PUK Microscope may only be used in combination with PUK precision welding machine
•The PUK Microscope may only be used when properly connected.
•Use for other than the proper purpose describe is not permitted.
Use in outdoor areas is not permitted. Use only in dry room areas!
SECTION 2 – INTRODUCTION
Arc welding without protective equipment is dangerous and can lead to painful inflammation of the
cornea and irreversible clouding of the eye lens (cataracts). The PUK-SM with its integrated LCD –
welder view protection filter offers reliable protection against these dangers and permanently protects
against UV/IR rays, sparks and splashes at both light and dark levels. The filter’s protection levels are
defined to avoid blinding from arc welding. The PUK-SM should only be used for welding if the LCD
welder view protection filter is mounted and only together when using a PUK spot welding device.
Shortly prior to lighting an arc, the electronic component of the PUK spot welding device switches the
filter from the DIN 3 level to the safer DIN 11 dark level. As soon as the arc is turned off, the filter is
switched back to the light setting.

SECTION 3 – GENERAL SAFETY INSTRUCTIONS - READ BEFORE USING
3-1. SAFETY INSTRUCTIONS
•Opening the device is permitted only by
trained experts. Before opening the device,
remove the plug and make sure that there is
no electrical current in the device. If you are
uncertain, always first ask an expert.
•Remove the plug before exchanging the
energy saving light and only touch the light
when it has cooled down sufficiently. Only
use energy saving lights with a maximum
output of 9 W.
•It is illegal for non-electrical professionals to
handle parts which are directly connected to
the mains voltage, except in cases of using
the mains plug or the mains central switch.
•During maintenance or repair work of the
electrical source, first separate the device
from the mains. In the case of more complex
activity where you must leave the work area –
even for a short time – you are also required
to clearly block the plug outlet.
•If it is clear that there is some danger
involved in your activities, you must take the
device out of operation and also prevent
unintentional operation. It is clear that a
dangerous situation is at hand when:
othe device shows visible damage, or
oor when functional errors occur
othe device no longer works properly.
3-2. EYE PROTECTION WHILE WELDING
•Do not look into the arc without eye
protection; only use welding protection
visors which are made from regulation-
approved protective glass.
In addition to light and heat rays causing blinding
or burning, the arc also emits UV rays. Without
sufficient protection, these invisible ultraviolet
rays cause very painful conjunctivital
inflammation noticable after several hours.
•Any persons or helpers who are working
near the arc should also be made aware of
the dangers and be equipped with the
proper required protection. If necessary,
protective walls should be set up.
SECTION 4 – SAFETY PRECAUTIONS - READ BEFORE USING
4-1. Arc Welding Hazards
►The symbols shown below are used throughout
this manual to call attention to and identify
possible hazards. When you see the symbol,
watch out, and follow the related instructions to
avoid the hazard. The safety information given
below is only a summary of the more complete
safety information found in the Safety
Standards listed in Section 4.2 Read and follow
all Safety Standards.
►Only qualified persons should install, operate,
maintain, and repair this unit.
►During operation, keep everybody, especially
children, away.
ARC RAYS can burn eyes and
skin.
Arc rays from the welding process
produce intense visible and invisible
(ultraviolet and infrared) rays that
can burn eyes and skin. Sparks fly
off from the weld.
_ Wear a welding helmet fitted with a proper shade of
filter to protect your face and eyes when welding or
watching (see ANSI Z49.1 and Z87.1 listed in
Safety Standards).
_ Wear approved safety glasses with side shields
under your helmet.
_ Use protective screens or barriers to protect others
from flash and glare; warn others not to watch the
arc.
_ Wear protective clothing made from durable, flame-
resistant material (leather and wool) and foot
protection.
FLYING METAL can injure
eyes.
_ Welding, chipping, wire brushing,
and grinding cause sparks and
flying metal. As welds cool, they can throw off slag.
_ Wear approved safety glasses with side shields
even under your welding helmet.

(Figure 2)
5-4. Operation
A. First steps
The lighting switch is located on the microscope cable.
1. Turn on the main switch (22).
2. The angle of the lighting can be set using the adjustment knob (14) which can be used
to change the lens direction.
B. Setting the eye viewing distance
1. Look through the eyepiece (1) and move the eyepiece tubes (3) by holding the prisma
casing (4) tightly and moving it to the left or the right.
2. The eye distance is correct once the field of view can be completely seen through
both eyepieces and both views combine into one field of view.
3. The eye viewing distance should be adjusted individually for each user.
C. Focussing
1. Use the zoom button (11) to set the lowest enlargement setting (1x).
2. Place a flat object in the middle of the welding table (8).
3. Turn the focus knob (15) to a middle focus range.
4. The attachment support (17), located on the tripod column (19), can be moved up or
down depending on the size of the object of focus.
a. Hold the attachment support (17) with one hand without touching a lens and
loosen the knob (16) on the attachment support (17) with the other hand. The
attachment support can now be moved all the way down to the base (9).
b. Look through the eyepiece and move the attachment support upwards or
downwards until the object comes into focus.
c. Pull the attachment support’s adjustment knob (5) tightly once more. Do not
release the attachment yet.

9
d. Slide the adjusting ring (18) back up towards the attachment support and fasten
the ring tightly. Now the attachment can be released.
e. It is not necessary to reset the attachment each time an object is changed, unless
the object extends beyond the focus range.
5. Bring the image into sharp focus using the focus knob (15).
D. Setting the diopters
The rings for diopter setting (2) are located on the eyepiece tubes.In a normal position, the
lower section of the case is adjusted to the marking on the eyepiece.
For different vision abilities:
1. Open the right eye only, look through the right eyepiece (1) and set the focus using the focus
knob (15).
2. Then use the left eye to look through the left eyepiece and adjust the focus by turning the
diopter regulator (2) on the left tube (3) until the image comes into focus.
D. Changing the zoom.
1. Use the zoom button (11) to set the lowest enlargement setting (4x).
2. Although the stereo microscope comes with a parfocal setting, the focus must be adjusted
since lenses with lower zooms offer larger field depths. Field depth is the ability to focus
on single points on various levels.
3. Once the image is in focus using the highest enlargement lens, it is not necessary to set
the focus when using lower enlargement lens.
SECTION 6 – CARE AND MAINTENANCE
6-1. Routine Maintenance
The PUK-SM requires a minimum of care and maintenance when used under normal working
conditions. However, several points must be observed in order to guarantee functioning and to keep
the device in proper working order for many years to come.
•Cover the PUK-SM with the dust cover when finished
•Regularly check the mains plug, mains cable and connective plug and cable to the welding device
for damage
•Clean the device occasionally using a soft cloth or pressed air
CONTACT YOUR DEALER WHENEVER MAINTENANCE OR REPAIRS ARE NEEDED THAT ARE
NOT DESCRIBED IN THESE OPERATING INSTRUCTIONS.

6-2. Maintenance of optic components
Do not disassemble optic components. Please contact your local customer technical sevice to
handle repairs not covered by these instructions.
Before cleaning the lens surface, first remove dust using a special brush or pressurized air.
Suitable cleaning tools may be purchased from any camera shop.
1. Cleaning the eyepieces
a. Do not remove the eyepieces (1) from the eyepiece tubes (3).
b. Clean the outer surfaces and breathe on them while doing so.
c. Then dry the lens using special paper. Dry the lens using circular motions from the center to
the outside edges. Do not wipe lenses that are already dry since lenses are very easily
scratched.
2. Cleaning the lens.
a. Do not remove the lens from the microscope.
b. Clean the surfaces only. To clean, use a soft cotton cloth moistened with xylol / xylene. Then
use the same cloth to dry the lens.
6-3. Maintenance of electrical components
1. Changing the lamp units
a. Unscrew the protective tube and the lamp shade of the lighting unit (13) by turning in a
counter-clockwise direction and removing it from the lamp frame.
b. Carefully use a cloth to pull the lamp from the holder and insert a new lamp.
c. Replace the lampshade by turning in a clockwise direction and screwing it into the lamp
holder.
d. The lamp must be cleaned if accidently touched with bare hands, otherwise the illuminative
power and life span of the lamp will be affected.
6-4. Maintenance of mechanical components
1. Adjusting the focus tension.
The tension is pre-adjusted by the manufacturer. At an optimal tension point, the focus
head moves easily without the attachment sliding downwards due to its own weight.
The focus tension ring (Fig. 1) is located between the focus knob (15) and the head
support (17).
a. To increase tension, turn the tension ring by using the tool included (Fig. 3) and turning in
a clockwise direction (A); to reduce tension turn in a counter-clockwise direction (B).
