14.1 Electrode welding process
Â
Use button 20 to select the electrode mode (LED
electrode 21 lights up).
Â
Use the selection buttons 32 or 33 to select the pa
-
rameter electrode diameter (LED 42 lights up).
Â
Use knob 34 to set the desired electrode diameter.
Â
Use the current mode selection button 27 to set the
desired current mode.
Â
Use the selection buttons 32 or 33 to select the pa
-
rameter main current I1 (LED 43 lights up).
Â
Use the rotary knob 34 to set the desired current
intensity. If the current intensity does not match the
selected electrode diameter then the warning LED
lights 50 up. Nevertheless, it is possible to weld.

The factory setting values are optimised thanks to auto-
matic parameters.
You can use these factory settings unchanged for most
welding jobs.
Further fine adjustment facilities can be found in Chapter
„14.3 Secondary parameters“ on page 44.
14.2 TIG welding process
Â
Select the desired mode with button 20.
–
2-stroke mode (LED 26 lights up).
–
4-stroke mode (LED 25 lights up).
–
Spots mode (LED 23 lights up, only for 2-stroke).
–
2-stroke pulse mode (LED 22 and LED 26 light
up).
–
4-stroke pulse mode (LED 22 and LED 25 light
up).
Â
Use the selection buttons 32 or 33 to select the pa
-
rameter electrode diameter (LED 42 lights up).
Â
Use knob 34 to set the desired electrode diameter.
Â
Use the current mode selection button 27 to set the
desired current mode.
Â
Use the selection buttons 32 or 33 to select the pa
-
rameter main current I1 (LED 43 lights up).
Â
Use the rotary knob 34 to set the desired current in-
tensity. If the current intensity is not appropriate for
the selected tungsten electrode diameter, LED 50
lights up. Nevertheless, it is possible to weld.

HF ignition
Danger due to electric shock!
If function HF-ignition (31) is selected,
a high ignition voltage is present at the
torch.
Never touch the welding electrode or parts
conducting welding current when the de-
vice is switched on.
HF ignition is a contactless ignition brought about by
high-voltage impulses.
Â
Using the current type button, select 27 HF ignition
(LED HF 31 lights up).
