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.

The welding current increases automatically as the welding volt-
age is reduced. The arc dynamic indicates the ratio between the
main current and the automatic increase.

Ignition using the Positive current is used for optimum dome for-
mation in TIG AC welding. This positive current is preset in the unit
and can be increased or reduced by the quoted percentage.

The ignition peak current is set after ignition to provide stabilisa-
tion of the arc. This ignition peak current is preset in the unit and
can be increased or reduced by the quoted percentage.

HF ignition is a contactless ignition brought about by high-voltage
impulses.
Powermaster LED 3
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).
Powermaster LED
lock
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
LED/
seconds, the mode button is immediately locked.
Code
up / down lock
ON: during the welding (I>0), the up / down buttons at the torches
of the i-LTG/i-LTW-series are locked.
Torch protect
2
ON: if a torch of the i-LTG/i-LTW –series is used, only a welding
current up to the max. torch strain limit can be adjusted at the
welding machine.
cooling permanent
ON
2
AUT: water cooling unit (WUK) switches on / off automatically.
ON: after the first current (I>0) the WUK is switched on and stays
on permanently.
