Note!
The PUK 3s will only work when hooked up to a supply of inert
gas and only when the machine is receiving enough pressure
(ca. 2 litres / min).
If inert gas is not hooked up, not flowing or if the pressure is
too low, the display will show the following reading: “Gas
error!! Check pressure”.
Connect power supply:
Connect mains lead to the back of the unit (15) and plug into the mains outlet.
Switch the mains power switch (11) to “ON”. The display will show the following important
safety warning
“Warning! Protect your eyes Read and follow the manual”
.
Confirm the compliance with these safety instructions, by pressing any button. Following
this, the machine will run a self-test.
Note!
Please read the instructions on the connected eye protection devices such as the
PUK-optic unit (welding shield) or MEZZO microscope with (welding shield)!
Caution!
As soon as the mains power switch is switched to “ON”, the terminal clamp (i.e.
crocodile clip) and cables receive electrical current. Please see to it that these
items cannot come into contact with any electrically conducting or earthed
materials. For the user / operator there is no danger, but unwanted operating
errors can occur.
4-5 CHANGING LANGUAGE DISPLAYED:
Languages available: ENGLISH – ITALIAN – SPANISH – FRENCH – GERMAN
The machine can be changed from English, to run in any of the 4 other languages
mentioned above.
Switch the machine on and confirm the safety notice displayed, so that the device starts
and is ready for work.
Now, press both the „Mode“ button (4) and the rotary-knob „Power“ (6), holding
them pressed for 2 seconds.
The language setting has now been changed to the next language in sequence. By re-
peating this process, the various languages available can be selected one after the other.

SET UP OF THE PARAMETERS AND OPERATION
After being switched on and running the self-test, the machine will start from its initial
settings:
Standard impulse, welding time 7ms and low output
The initial settings for mode, welding time and power, correspond to the blue LEDs in the
display. The display also has blue LEDs to mark the entire parameter range.
Important!
At the outset, until a basic proficiency is reached, we recommend to only change the
parameter welding power, leaving the welding time constant. After a short time, when
you have become more confident with the technique and have gained more experience,
then you can naturally also change the welding time to suit your needs.
The machine automatically saves the last three sets of welding parameters that
have been used.
By pressing in the rotary knob “Impulse length / welding time” (3), these previous settings
can be recalled one after another.
