14.3 Secondary parameters
Danger due to electric shock!
If function HF-ignition is selected, a high ig-
nition voltage is present at the torch.
Never touch the welding electrode or parts
conducting welding current when the de-
vice is switched on.
The secondary parameters are set separately:
 Press the welding process 30 and mode 47 buttons briefly
simultaneously.
9 The 7-segment display 38 alternately displays the code of
the secondary parameter and its value.
 Press the main parameter button 48 until the desired pa-
rameter appears.
 Use knob 41 to set the desired value.
 Briefly press the welding process 30 or mode 47 button to
end this mode.
9 The changed values are accepted.
For more effective adjustment, all welding
i i
parameters can be changed even during the
welding process.

HF ignition is a contactless ignition brought about by high-voltage
impulses.

Powermaster LED 4
All Powermaster torches of the i-LTG/i-LTW – series have two free
programmable parameter spaces. Depending on the type of weld-
ing machine and operating mode, different parameters can be
selected (please also see „14.4 Powermaster parameters" on page
40).

ON: mode button at the torch of the i-LTG/i-LTW serie is locked. By
pressing the mode button for 2 seconds, the button is unlocked
for 15 seconds. If the start/stop-button is pressed during these 15
seconds, the mode button is immediately locked.
