7.4 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 SM D2. 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. 

 

 

 

 

 
7.5 RESHARPENING 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 D2 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 A QUALIFIED ELECTRICIAN!
