Insert electrode:
(Figure 3)
(Figure 4)
Remove the nozzle (22) of the hand piece (25) (by pulling)
Loosen the electrode thread (24), insert the newly sharpened tungsten electrode (23) and
screw on tightly (per hand - do not use a wrench) with the electrode projecting ca. 5 – 8
mm out of the nozzle (Fig. 4)
(Only use original electrodes)
mount the nozzle
PLEASE NOTE!
Nozzle (22), electrode screw connection (24), electrodes (23) and pliers devices are

Connect eye protection:
Plug the round plug for the welding shield i.e. eye protection system (Mezzo / Optic unit)
into the connection socket (16) marked “SHUTTER” located on the back of the device and
secure it with the nut.
Warning!
Only the Lampert - eye protection systems "MEZZO welding microscope" or "PUK
optics unit" may be attached.
Other eye protection systems are not permissible and may lead to health damage
Connect inert gas supply:
Attach the pressure controller to the protective gas container after carefully reading the
instructions (if possible, use argon gas with a minimum of 99.8%, e.g. “Argon 4.6”
Connect pressure tube, by using the quick connectors, to the pressure controller and to
the gas connection (19) located on the back of the unit.
Open gas bottle valve and set the gas flow to between 2-4 liters per minute
maximum operating pressure should be 4 bars!
to adjust the quantity of gas keep the output regulator (6) pressed (the gas valve in the
machine opens) and adjust the correct flow rate (2 - 4 litres) using the pressure control
valve.
Note!
PUK 3 works only if inert gas is attached!
If no inert gas is attached, the display indicates "G-FAIL" and
the machine does not weld.
