The PUK U5 is equipped with a function to prevent the 
electrode becoming welded to the workpiece by 
incorrectly pressing too hard. If a welding point has 
already been set and is pressed too hard to the 
workpiece when it comes into contact again, the welding 

point is not triggered; instead, an acoustic signal sounds 
periodically to indicate that the electrode is pressing too 
hard against the workpiece. The electrode's contact to 
the workpiece must be stopped for a short time and the 
welding process must be started again. 

THE WELDING PROCESS CAN BE HALTED AT ANY TIME BY MEANS OF LIFTING THE ELECTRODE AWAY 
FROM THE WORKPIECE. 

 

7.2 WELDING WITH THE SPEED MODE (only PUK U5+)

You can press 
the according 

symbol 

 on 

the display for 1 
second to 
activate or 

deactivate the speed mode. The speed mode can only be 
activated on the start level, in the expert menu and on the 
"Custom Programs" level. The speed mode enables a 
faster welding sequence, e.g. for an increased heat input 
into the workpiece. If the user switches to a different user 
level, the speed mode must be reactivated if required.

 

 

7.3 WELDING WITH FOOT SWITCH 

(optional accessory)

With the  PUK  U5 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 BLUE 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 BLUE SYMBOL ON THE DISPLAY DISAPPEARS. 

 

7.3.1 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! 

Connect both of the workpieces which are to be fixed at 
an area of bare metal with a contact clamp, one to the 
blue one and the other to the black. When the two parts 
are touching, the welding process can be triggered, using 
the foot switch. The handpiece is not used during  

this process.

 

The required welding power is determined 

by the strength of the connection desired as well as the 
workpiece geometry. The welding time setting is of 
secondary importance in this mode, and can only be 
varied to a very limited extent. 

AFTER WELDING HAS BEEN SUCCESSFULLY COMPLETED, AND BEFORE SWITCHING TO ANOTHER 

USER LEVEL, PLEASE REMOVE THE BLUE CONNECTION CABLE!

NOTE: DURING FIXATION WELDING, THE FOOT SWITCH IS ALWAYS ACTIVE, AND CANNOT BE 
DEACTIVATED! DURING FIXATION WELDING THE GAS PROTECTION IS DEACTIVATED!
