DESIGNATED USE

- The viewing or examining under the microscope of objects by looking through the

eyeglass.

- The illuminating of the working area.

The USM may only be used with a PUK U3 – precision welding device.

The

USM

may only be used when it is correctly connected.

Any other application of the appliance other than the above stated, is prohibited.

It is prohibited to use this apparatus out of doors. Use only in dry surroundings!

INTRODUCTION

Arc welding without protective equipment is dangerous and can lead to a painful

inflammation of the cornea. It can also lead to an irreversible clouding of the eye lenses

(cataract).

The USM with its integrated LCD glare protection filter offers a reliable safeguard against

these dangers. It provides continuous protection against UV/IR-rays, as well as sparks

and splashes, both in the filters clear setting (Luminescence DIN3) as well as in its dark

setting (Obscurity DIN11).

The filter is constructed so that a dazzling from the glare of the electric arc is avoided.

Shortly before an electric arc is fired, the PUK U3’s electronic circuitry, switches the filter

automatically from its clear setting (Luminescence DIN3) to its dark setting (Obscurity

DIN11). The filter then returns to the clear setting again immediately after the electric arc

is extinguished.

The USM may only be used in conjunction with a PUK U3 precision welding device.

SAFETY INSTRUCTIONS

3-1 GENERAL SAFETY INSTRUCTIONS

The device may only be opened by a trained and qualified technician or electrician.

Before opening the device remove the mains plug from the wall socket, and make sure

that the machine is not receiving any electrical current. If you are unsure, or have any

questions, always consult a trained and qualified technician or electrician.

Before exchanging the LED module, remove the power supply plug. Only use original

replacement LED modules from Lampert.

Non qualified persons are prohibited by law from tampering with any electrical devices

that are connected to the mains power supply, or otherwise receiving current. Non

qualified persons may only operate the mains plug, power adapter or the main on/off

switch.

When carrying out repair or servicing work, the machine must always be disconnected

from the power supply. Throughout any work of longer duration, that requires the

qualified person to leave (even if only briefly) the place where work is being carried out,

the wall socket must also be securely closed off.

If it can be assumed that a safe operation of the device is no longer possible, then the

machine must be shut down and removed from the power supply; it must also be

secured against accidental re-operation or activation.

It is likely, and can be expected, that a safe operation of the device is no longer possible

when:

- The machine will not operate.

- When malfunctions occur.

- The machine will operate, but shows visible signs of damage.

3-2 PERSONAL SAFETY AND POTENTIAL RISKS

EYE PROTECTION DURING WELDING

Do not look into the arc without

adequate eye protection. Only use a welders’

protective glare shield that contains a protective glass which conforms to

regulations (protection class 11, minimum).

The electric arc radiates rays of heat and light that can cause the user to be burned or

dazzled. In Addition to this, the arc also gives off UV-radiation. If the eyes are not

adequately protected, these invisible ultraviolet rays can cause a very painful

conjunctivitis, the effects of which are only noticeable several hours after exposure.

Those lingering or working in close proximity to the electric arc, must be made aware of

the risks, and supplied with the appropriate protective equipment. Wherever necessary, a

protective screen should be erected.

EYE PROTECTION WHILST OPPERATING THE LED LAMP

Do not look into the

LED

Lamp, or into the reflection of the LED light, without eye

protection. Always use a welders’ protective glare shield with a minimum

protection class of 3.

INSTALLATION

SETUP INSTRUCTIONS AND COMENCING WORK

All stages of the microscope assembly must be carried out

with great care. The

individual parts must not be put together using excessive force.

Mount the bearing rod (11) to the base plate (13), using the bolt that is included; tighten it

with an open-ended spanner. Place upright, on a clean, flat, and stable surface.

Slide the rod for pitch adjustment (18) into the underside of the bearing rod. Secure it

using the retaining screw for pitch adjustment (15), which is screwed into the side of the

bearing rod and gently tightened.

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 the eyepieces (1) with eyepiece covers, and secure them with the locking screw

(4).

Attach the “control lead for LCD glare protection filter (Shutter)” (17), to the back of the

welding device. (Observe the guidelines in the instruction manual of the welding device).

Connect the LED light with the PUK U3.

Insert the mains cable (16) into the connection socket marked “LED-Lamp 800 mA”, on

the back of the welding device.

Please note!

Always test that the LCD glare protection filter (Shutter)

(6)

is working correctly

before you start welding.

By pressing

the rotary knob

–

Power

of the

“

PUK

”

welding device

, the

shutter can be tested. During this process, It will change from its clear setting to

its dark setting, and back again.

If the LCD glare protection filter (Shutter) doesn’t change from its clear to dark

setting, then it must be exchanged straight away. No welding may be done unless

the microscope has a fully functioning shutter.

Shortly after the machine is switched on, the welding device will run a self-test. During

the self-test, the LCD glare protection filter (Shutter) (6), will change from its clear setting

to its dark setting, and back again.

Each time the machine is used, make sure that the shutter is operating correctly, if

necessary start the self-test again. To do this, switch the machine off, wait several

seconds, and then switch it on again.

NSTRUCTIONS FOR USE

5-1 FIRST STEPS

Adjust the height and position of the supporting arm (12) so that, when both hands are

resting on the hand rests (14), the work piece can easily be guided to the tip of the

electrode. Here remember to first correctly position the hand-piece in the supporting

arm.

Switch the LED light on using the mains cable switch (16).

5-2 SETTING THE VIEWING DISTANCE

Look through the eye-pieces (1). By holding the prism casings (5), and moving them

inwards or outwards, the eye-piece tubes (3) can be adjusted to the correct viewing

distance for the user’s eyes.

The viewing distance is correct when the complete visual field can be seen through

both eyepieces and both views combine to produce the effect of a single field of vision.

The viewing distance should be individually set for each user.

5-3

FOCUSING

Mount the welding hand-piece in the supporting arm. Make sure that the hand-piece

has an electrode inserted and is correctly positioned.

Turn the rotary knob - focus (10) until a focus setting is achieved, which is midway

between the min. and max. focus setting.

Adjusting the height of the microscope head mount:

Hold the microscope head (8) in one hand, (avoid touching the microscope lens). With

the other hand loosen the retaining screw of the microscope head mount (9). The

microscope head can now be freely adjusted in height.

Look through the eyepieces and slide the microscope head up or down on the bearing

rod until the object is in focus.

Tighten the retaining screw of the microscope head mount again.

Ensure a sharp image by adjusting the rotary knob - focus (10).

5-4 DIOPTER SETTINGS

The ring for dioptric adjustment (2) is located on the left eye-piece tube (3). In the

normal position, the lower part of the sleeve is aligned with the marking on the eye-

piece tube.

When a user’s eyes have differing strengths of vision:

With only the right eye open, look through the right eye-piece (1) and set the focus

using the rotary knob - focus (10).

Now, with only the left eye open, look through the left eye-piece and adjust the focus by

turning the dioptric adjustment (2) on the left eye-piece tube (3) until the viewed object

is in focus.

CARE AND MAINTENANCE

Under normal working conditions, the stereo microscope “USM” needs only a minimum

of maintenance and care. However there are a few vital points, which when observed will

ensure that the device gives lasting service in the years to come.

After finishing working with the “USM”, always cover it with its dust protection cover.

Every so often please check all cables and plugs to make sure that they are not

damaged.
