7.4 ABRADING THE ELECTRODES
Please switch off the machine prior to exchanging
the electrodes. This prevents uncontrolled
triggering of the welding process.
If possible, the electrodes should be sharpened with a
diamond disk with fine or medium grain.
The recommended angle of grinding is approx. 15°.
8. CARE OF THE SYSTEM COMPONENTS
8.1
CARE OF WELDING DEVICE AND WELDING MICROSCOPE
Your PUK U4 as well as the welding microscope require a
minimum
of
maintenance
under
normal
working
conditions
. However, it is essential that a few points are
observed in order to guarantee the functionality and to
keep the spot welding device fully operational for years to
come.
•
Check the mains plug and cable as well as all welding
and connection cables regularly for damage.
•
Check that the moving parts of the handpiece move
easily.
•
If necessary, clean the electrode threaded assembly on
the handpiece, in order to ensure optimal contact with
the electrodes.
•
Clean the device occasionally with a suitable cloth.
•
Use the supplied dust cover to cover up the microscope
after use.
IF WORK OR REPAIRS THAT ARE NOT DESCRIBED IN THESE OPERATING INSTRUCTIONS ARE NECESSARY
THEN CONTACT YOUR DEALER.
WARNING!
IF FUSES REQUIRE EXCHANGING, THEN THEY MUST BE REPLACED WITH FUSES OF THE SAME TYPES
AND VALUES.
THE GUARANTEE IS VOID IN THE EVENT OF EXCESSIVLY HIGH FUSING!
THE DEVICE MAY ONLY BE OPENED BY AUTHORISED CUSTOMER SERVICE PERSONNEL!
8.2
CARE OF THE OPTICAL COMPONENTS
Do not attempt to disassemble optical components.
Please contact the local technical customer service
department for repairs which are not covered by this
manual.
Remove dust from the lens surface with a special brush
prior to cleaning. You can obtain suitable accessories in
any photography store.
Cleaning the oculars: Do not remove the oculars (19) from
the ocular tubes (17).
Clean the outer surfaces. In doing so, blow on them.
Subsequently dry the lens with suitable cloth or paper for
the purpose. Dry the lens with circular movements from
the centre to the outside. Do not wipe over a dried lens as
they can easily be scratched.
Cleaning and exchanging the protective glass of the eye
protection filter:
Never dismantle the eye protection filter
(shutter)!
Only clean the surface. Use a cotton cloth with glass
cleaner.
If the protective glass requires exchanging, slide it
forwards out of the bracket and insert a new protective
glass in the same manner.
