11.3 Electrode welding process
Connecting the electrode welding cable
:> Connect the electrode welding cable to the minus
or plus socket 8 and secure the cable by rotating it
clockwise.
The polarity of the electrode depends on
the type of electrode and the welding pro-
cess. Please f ollow the manufactu r er's in-
structions on the electrode packaging for
this purpose.
11.4 TIG welding process
For TIG welding you req ui re a TIG valve
torch (Type L
TV2600) for this device
Installing electrodes
21 20
:> Unscrew the clamping cap 17.
:> Remove the electrode 16 from the collet 18.
:> Gri nd the end of the electrode 16.
:> Slide the electrode 16 into the collet 18 .
:> Insert the electrode 16 into the tor ch and firmly tight-
en the clamping cap 17 .
Do not
dismantle the collet body 20 and the
gas nozzle 21.
When converting the torch to a different
electrode diamet er , please pay attention to
the following.
0 The collet 18, collet body 20 and electrode 16 must
have the same diameter.
0 The gas nozzle 21 must be matched to the electrode
diameter.
Connecting the TIG torch
:> Connect the TIG torch to the minus 8 connection
socket and secure it by turning it
clockwi se.

Fig. 4: Gas connection
:> Place the inert gas cylinder 28 in a suitable location
and secure to prevent it from falling over.
D The cylinder can be secu red using a wall bracket or
cylinder
troll ey .
:> Briefly open the gas cylinder valve 27 several times
in order to blow out any dirt particles that are presen t.
:> Connect the pressure reducer 22 to the inert gas cyl-
inder 28.
:> Screw the inert gas hose 24 to pressure reducer 22
and open the gas cylinder
valve 27.
Setting the inert gas quantity
:> Open the valve 19 on the TIG welding torch .
./ Inert gas flows out.
./ The flow met er 23 indicates the gas quantity, and
the content pressure gauge 26 indicates the cylinder
content.
:> Close the valve 19 on the TIG welding torch when the
torch is not being used
in order to prevent unneces-
sary use of gas.
