power of the welding equipment (see Tech-
nical Data).
– If the generator is overloaded, then arc puls-
ing or an arc breakaway is possible.
Mains extension cables
‰ Only use intact mains extension cables which
offer the specified protection.
‰ Coiled cables may heat up considerably. Always
unwind extension cables fully.
When particularly long mains extension cables
are used, the mains voltage on the machine may
fall to such an extent that the welding power
falls. Shorten the extensions and/or use exten-
sions with a larger cable cross-section.
13.4 Electrode welding process
Connecting the electrode welding cable
Connect the electrode welding cable to the
minus 6 or plus 3 socket and secure the cable by
rotating it clockwise.
Note the manufacturer's informa-
i
tion when selecting a suitable stick
electrode. The electrode diameter is
dependent upon the thickness of the
material to be welded.
Electrode welding with positive (+) electrode:
 Connect the electrode holder to the positive
terminal 3 of the machine and secure it by turn-
ing the plug to the right.
Electrode welding with negative (-) electrode:
 Connect the electrode holder to the negative
terminal 6 of the machine and secure it by turn-
ing the plug to the right.
 Push the lever on the handle of the electrode
holder. Clamp an electrode with the exposed
end in the holder. Note the notches on the in-
ner side of the two jaws.
13.5 TIG welding process
Risk of electrical shock!
The torch is exposed to high ig-
nition voltage when the HF ig-

selected.
Installing electrodes
 Unscrew the clamping cap 55.
 Remove the electrode 54 from the collet 53.
 Grind the end of the electrode 54.
 Slide the electrode 54 into the collet 53.
 Insert the electrode 54 into the torch and firmly
tighten the clamping cap 55.

When converting the torch to a differ-
‰ The collet 53, collet body 51 and electrode 54
must have the same diameter.
‰ The gas nozzle 50 must be matched to the elec-
trode diameter.
Connecting the TIG torch
 Plug the torch control plug 57 into the connect-
ing socket 4.
 Connect the TIG torch 58 to the negative ter-
minal 6 and secure it by turning it to the right.
 Connect the torch's gas line to gas connection
5.
Connecting the inert gas cylinder
 Secure the inert gas cylinder 60, e.g. by using a
securing chain.
 Briefly open the gas cylinder valve 61 several
times in order to blow out any dirt particles that
are present.

ent electrode diameter, please pay at-
tention to the following.
Risk of electrical shock!
Connection socket 4 may only be
connected to the control plug of
the TIG torch. Never plug in other
control devices such as the relay
contact of an automation controller
or a manual button, as the socket is
always exposed to full ignition volt-
age, even when no control plug has
been inserted.
