 Press keys „1" 48 and „2" 46 shortly at the time.
9 The 7-segment-display shows alternating the parameter-
code and the corresponding adjustment value.
 The adjustment valiue can be set by turning knob 45.
 By pressing key „1" 48 or „2" 46, the previous or subsequent
secondary parameter will be displayed.
‰ Depending on selected mode and function, different se-
condary parameter are available.

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

Indicates the relation in percentage between welding current l1
and secondary current l2. If the set value is 30, the relation is 30%

correction
Ignition using the positive current is used for optimum dome for-

All Powermaster torches of the i-LTG/i-LTW – series have two free
programmable parameter spaces. Depending on the type of wel-
ding machine and operating mode, different parameters can be
selected (please also see „13.5 Powermaster parameters" on page
35).

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
x
for 15 seconds. If the start/stop-button is pressed during these 15
seconds, the mode button is immediately locked.
up / down lock
x
ON: during the welding (I>0), the up / down buttons at the torches
of the i-LTG/i-LTW-series are locked.
Torch protect
x
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.
