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.

SECTION 5 – OPERATION AND INSTRUCTIONS

5-1. UNPACKING

All stereo microscope components have been packaged carefully so that you can receive

them in perfect condition. We recommend that you keep the packaging material. It may be

required again should you have to send in the microscope or wish to store it for a longer

period, or whenever the mircoscope needs to be transported to a technical customer service

center for maintenance or repair.

Packaging includes:

•SMZ-140 (binoculars): A base with a tripod column to add a movable, lighted upper

component. A binocular top section with eyepieces, eyepiece covers and a

protective cover for the microscope

Please remove and handle all microscope components very carefully.

Avoid touching the lenses and optical elements. Also avoid contact with dust, water and

other dirt-causing substances, as they can smudge or damage the lens surface and affect

image quality.

5-2. ASSEMBLY AND START-UP

Please perform all work stages involved in assembling the stereo microscope very

carefully. The stereo microscope’s individual parts and elements should not be

assembled too forcefully.

•Place the base of the microscope (9) upright on a flat, clean and secure surface

•Move the attachment support (17) over the tripod rod (19) and screw it on tightly.

•Mount the adjusting ring (18) under the attachment support

•Move the face protector (25) over the microscope head

•Place the microscope head (10) into the head support and screw it on from both sides

•Screw on the ancillary lens (objective) (6)

•Screw the shutter (7) on to the ancillary lens and secure it into the correct position using

the bolt (23)

•Plug the light plug (12) into the socket on the top side of the tripod

•Connect the control line (20) to shutter with the welding device

•Assemble the welding table (8) and mount it on the tripod base (Fig. 2)

•Connect the connective lamp cable to the transformer

•Insert the mains plug into a suitable electrical outlet.

WARNING: Before connecting the stereo microscope to the electricity supply,

check that the electricity supply voltage is compatible with the voltage labelled on

the stereo microscope.

•During a self-test immediately after switching on the welding device, the shutter (7) will

quickly turn dark and then light again. Run this test each time prior to beginning your

work, to ensure that the view protection filter functions perfectly. If needed, start the self-

test again by turning the welding device off and then on again.

WARNING: Keep a minimum 50 mm distance between the light and the workpiece

and/or the welding table.

ATTENTION!

Before welding, always check that the protective filter (shutter)

functions properly.

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.
