6.12 Retention (if activated in the settings)
After activation, the retention welding mode
appears as a separate user level, which can be
accessed by pressing the rotary controller for one
second.
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 device 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 D5.
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.
Without foot switch
The welding process itself proceeds automatically:
The 1st light touch of the workpiece pulls back the pin welding adapter, and a continuous tone sounds for
approx. 3 seconds.
The 2nd light touch triggers the welding process (during the continuous tone).
With foot switch
The foot switch can be activated by pressing and holding it (approx. 2 sec.). An info message and a blue
symbol appear in the display.
The 1st light touch of the workpiece pulls back the pin welding adapter.
With the 2nd light touch, the eye protection system (shutter) in the microscope can be clearly seen flickering.
Pressing the foot switch at this stage triggers the welding process.
Pressing and holding the foot switch (approx. 2 sec.) (without touching a workpiece) causes it to be deactivated
and the blue symbol on the display disappears.
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.
