Secondary parameters
The secondary parameters are set separately:
 Hold down the mode button 20, press the save but-
ton 58.
 With the selection buttons 32 or 33 select the desired
secondary parameter
9 In the left 7-segment display 36 the code of the pa-
rameter is displayed, in the right 7-segment display
35 the value of the parameter.
 Use knob 34 to set the desired value.
For more effective adjustment, all welding
i i
parameters can be changed even during
the welding process.
Parameter
ACS = AC-Standard,
AC
1, 3
ACH = AC-Hard
The AC parameter in the AC-Standard basic setting enables
working with low-noise arcs and good re/ignition behaviour.
For pure aluminium it may be necessary to switch over the
parameter to AC-Hard.
ACS = soft and quiet arc
ACH = very stable and hard arc
Arc dynamic
0 - 200 %
2
The welding current increases automatically as the weld-
ing voltage is reduced. The arc dynamic indicates the ratio
between the main current and the automatic increase.
Ignition peak
10 - 200 %
correction
3
The ignition peak current is set after ignition to provide
stabilisation of the arc. A different ignition peak current is
saved in the unit for each selected electrode diameter. This
ignition peak current can be increased or reduced by the
quoted percentage.
Positive current
10 - 200 %
correction
1, 3
Ignition using the positive current is used for optimum
dome formation in TIG AC welding. A different positive cur-
rent is saved in the unit for each selected electrode diam-
eter. This positive current can be increased or reduced by
the quoted percentage.
MACS
0,2 - 5 Hz
frequency
1, 3
10 - 90 %
MACS balance
1, 3
alternating current
Indicates the percentage ratio between alternating current
(AC) and direct current (DC). If the value set is 60, the ratio
is 60% AC to 40% DC.
0 - 99, JOF=JobOff
Job no. for CWF
3
or FOF=FeedOff
For job selection on a connected wire feeder (e.g. Lorch
Feed 1).
0 - 99 = corresponding job selected
JOF = job selection switched off
FOF = wire feeder is switched off

Parameter
Feed Start with
2nd stroke
When set at "On" and 4-stroke operating mode, the wire
feeder (e.g. Lorch Feed 1) only starts with the 2nd stroke.
2. Torch button
Function assignment of the second current torch button 76.
On = normal function (second current)
OFF = no function
fd2 = starts feed for as long as the button is pressed (2-stroke)
fd4 = starts feed with the first activation of the button, stops
feed by activating the button a second time (4-stroke)
LorchNet
Connector
Only available if LorchNet Connector is connected (see
LED/
user manual LorchNet Connector).

Slopes
The current increase or decrease can be turned on or off.
When set at Slopes OFF, current increase, decrease, Start cur-
rent and final current are not available in the main parameters.
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 welding machine and operating mode, different
parameters can be selected (please also see „14.4 Pow-
ermaster parameters" on page 45).
If the wire feeder FEED is connected, parameter space
PL3 is always "fdS".
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 seconds, the mode button is
immediately locked.
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
AUT: water cooling unit (WUK) switches on / off automati-
cally.
ON: after the first current (I>0) the WUK is switched on and
stays on permanently.
