4.4 CONNECT SHIELDING GAS SUPPLY:
Fasten the suitable flow regulator to the shielding gas
tank. ATTENTION: In doing so, always observe the
enclosed special operating instructions provided. (Where
possible, use argon with min. 99.8% purity, e.g. "Argon
4.6"). The pressure hose is to be fastened by hand with
the help of the quick coupling adapter to the flow regulator
as well as the shielding gas connector (10) on the rear of
the device.
CHECK REGULARLY THAT ALL OF THE HOSE CONNECTIONS AND GAS HOSES ARE IN OPTIMAL
CONDITION, ARE PROPERLY FASTENED AND ARE AIRTIGHT!

INSERTING THE ELECTRODES INTO THE WELDING HAND PIECE:
PLEASE ALWAYS CHECK THAT THE MACHINE IS SWITCHED OFF, PRIOR TO EXCHANGING THE
ELECTRODES. THIS PREVENTS UNCONTROLLED TRIGGERING OF THE WELDING PROCESS.
(Fig. 3)
(Fig. 4)
(Fig. 5)
Lightly rotate the nozzle (12) back and forth and in doing
so, pull it off of the hand piece (15). It is only pushed-on,
not screwed in place.
Release the threaded electrode connection (14), insert a
well sharpened tungsten electrode (13) and tighten up
(hand-tight – do not use a tool to tighten).
The correct length for the electrode can easily be checked
and corrected if necessary by means of the milled marks
on the handpiece clamping arm (Fig. 4).
Now replace the nozzle.
The electrode must protrude approx. 4 - 6mm out of the
nozzle (Fig. 5).
ONLY USE THORIUM OXIDE FREE ORIGINAL ELECTRODES
Subsequently insert the connector of the hand piece as
straight as possible into the socket (28) on the front of the
PUK and fasten in place by tightening the coupling nut
hand-tight in a clockwise direction. Insert the connecting
cable used into one of the sockets (27) on the front side of
the housing.
4.6 CONNECT POWER SUPPLY:
Insert the power cable with the mains connector into the
corresponding socket (2) on the rear of the housing and
insert the mains plug into a suitable socket with the correct
mains voltage.
CAUTION!
AS SOON AS THE MASTER MAINS SWITCH ON YOUR
PUK U4 IS SWITCHED ON, THE VOLTAGE IS APPLIED
TO THE CONNECTED CROCODILE CLIPS OR CABLES.
IT IS TO BE ENSURED THAT THESE PARTS ARE NOT
ALLOWED
TO
COME
INTO
CONTACT
WITH
ELECTRICALLY CONDUCTIVE OR EARTHED PARTS,
SUCH AS THE HOUSING, ETC. IN DOING SO, THERE
