7.2 WELDING WITH THE SMOOTHING MODE
You can press
the "TIME" scale
on the display
for 2 seconds to
activate or
deactivate
smoothing
mode. The
smoothing mode can only be activated on the start level,
in the expert menu and on the "Custom Programs" level.
Smoothing mode enables a faster welding sequence, e.g.
to smooth surfaces or to weld with an increased heat
transfer (e.g. to reduce the conductivity of silver). If the
user switches to a different user level, smoothing mode
must be reactivated if required.
7.3 RETENTION WELDING INSTRUCTIONS
This mode is used for the welding of CoCr or NiCr-alloy retention pins using the relevant pin welding adapter (Ø 1.2, 1.3, 1.5
or 2 mm).
Please switch off the machine prior to
exchanging the electrodes or the adapter. This
prevents uncontrolled triggering of the welding
process. Remove the electrodes, replace the
clamping nut and chuck with the pin welding adapter.
Work without the clamping nut and nozzle. Then select
the diameter of the adapter being used, by pressing the
respective button on the display of the PUK D3.
Then connect the workpiece to an area of bare metal,
using a contact clamp. Insert a pin of the appropriate
diameter into the pin welding adapter. No shielding gas
flows during the whole process..
The welding process itself proceeds automatically:
•
The 1
st
light touch of the workpiece pulls back
the pin welding adapter, and a continuous tone
sounds for approx. 3 seconds.
•
The 2
nd
light touch triggers the welding process
(during the continuous tone).
A good welded connection is indicated by a clearly
audible welding noise. If the process passes off without
making a noise, then the connection is presumably of
insufficient strength. Blasting or roughening polished
welding points before welding may have a positive effect
on welding behaviour for pin welding.
FOR INFORMATION ON RETENTION WELDING USING THE FOOT SWITCH, SEE ALSO CHAPTER 7.4.2.
7.4 WELDING WITH FOOT SWITCH
With the PUK D3 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 the rotary controller or touching
the screen 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.). AN INFO
MESSAGE AND A WHITE SYMBOL APPEAR IN THE DISPLAY.
Connect a metallic blank
section of the workpiece
with the contact clamp.
Now
lightly touch the
workpiece
with
the
electrode. The eye protection system starts to turn
periodically from its light to its dark setting. 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 WHITE SYMBOL ON THE DISPLAY DISAPPEARS.
7.4.1 FIXATION WELDING
THE BLUE CONNECTION CABLE MAY ONLY BE CONNECTED AFTER THE MODE HAS BEEN ACTIVATED.
AFTER WELDING IS COMPLETE, IT IS VITAL THAT THIS CABLE IS REMOVED AGAIN, BEFORE SWITCHING
TO ANOTHER MODE, IN ORDER TO AVOID FAULTY WELDS!
