7.2 WELDING WITH FOOT SWITCH
(optional accessory)
With the PUK04 switched off, connect the foot switch to
the socket (4) marked with the blue foot switch symbol on
the rear of the device. Switch the device on, confirm the
safety prompt by pressing an arbitrary button and wait for
the self-test to conclude. The device is now ready for
operation.
THE FOOT SWITCH CAN BE ACTIVATED BY PRESSING AND HOLDING IT (APPROX. 2 SEC.). A BLUE DOT
APPEARS IN THE DISPLAY.
Connect
a
metallic
blank section of the
workpiece
with
the
contact
clamp.
Now
lightly touch the workpiece with the electrode, so that the
shielding gas flows out. If the foot switch is operated in this
mode, the welding process will begin automatically as
described in chapter 7.1.
PRESSING AND HOLDING THE FOOT SWITCH (APPROX. 2 SEC.) (WITHOUT TOUCHING A WORKPIECE) CAUSES
IT TO BE DEACTIVATED AND THE BLUE DOT ON THE DISPLAY DISAPPEARS.
7.3 BASICS AND TIPS
IMPORTANT!
Always work with a well sharpened electrode (see point
7-4 for information about sharpening the electrodes).
Ensure extremely good contact between the workpiece
and the contact clamp, i.e. make contact between the
workpiece and the connection cable terminal at a point
which is metallically blank.
Never weld "free hand", i.e. use the hand rests of the
microscope SM04. Shaking hands can cause the
configured parameters to be falsified.
Apply only light force to the electrode tip.
Weld with the correct gas flow of 2 litres/minute and
check this regularly.
With a little experience you will notice that the angle
with which you touch the workpiece with tip of the
electrode affects the "direction of flow" of the welding
point.
The electrode can easily be clamped in somewhat
longer for welding recessed areas.
In many cases it is helpful to work with welding wire as
a welding supplement, but never with solder.
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 PUK04 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.
