12 .3 Connect to mains
Before you operate the device, make sure
that a suitable mains power supply is availa-
ble. Fuse protection shall correspond to the
technical data.
Alternatively you may connect the device to
a power generator. Please note:
‰ If you want to use the full power range of
the welding equipment, the output power
of the generator must at least match the
input power of the welding equipment
(see Technical Data).
‰ In case the generator gets overloaded, an
uncontrolled pulsation of the arc may oc-
cur or the arc collapses.
Mains cable extensions
‰ Use exclusively flawless cables which
meet the fuse protection.
‰ Coiled cables may heat-up! Always un-
wind the extension cables completely.
Using a very long cable extension, the
mains voltage at the device may drop and
the welding performance decreases. Shor-
ten the extension or/and use an extension
with larger conductor cross section.
12 .4 Electrode welding process
Connecting the electrode cable
Connect the electrode cable to the minus 8
or plus 7 socket and secure the cable by tur-
ning it to the right.
Note the manufacturer information
i
when you select a suitable stick
electrode. The electrode diameter
depends on the thickness of the
material to be welded.
Welding with positive (+) electrode:
 connect the electrode holder to the positi-
ve pole connector 7 and lock it by turning
the plug clockwise.
Welding with negative (–) electrode:
- 32 -
 connect the electrode holder to the nega-
tive pole connector 8 and lock it by turning
the plug clockwise.
 Press the handle at the grip of the elect-
rode holder. Clamp the electrode with its
blank end in the holder. Consider when
doing the notch at the inner side of both
blocks.
12 .5 TIG welding process
For TIG welding a TIG valve-torch
i
is nec-essary (type LTV17)
Inserting the electrode
50 51
Abb. 12: Torch
 Unscrew the clamping cap 55.
 Push the tungsten electrode 54 through
the suitable clamping sleeve 53.
 Point the tungsten electrode 54 by grin-
ding.
 Push the tungsten electrode 54 through
the suitable clamping sleeve 53.
 insert the sleeve and rescrew the clam-
ping cap 55.
Do not dismount the clamping
i
sleeve casing 51 and the gas
nozzle 50.
