Starting up
Parameter
Ignition using the positive terminal is used for optimum dome
formation in TIG AC welding. This positive terminal current is
preset in the unit and can be increased or reduced by the quoted
percentage.
Ignition peak cor-
rection
The ignition peak current is set after ignition to provide stabilisation
of the arc. This ignition peak current is preset in the unit and can be
increased or reduced by the quoted percentage.

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 „12.5 Powermaster parameters" on page
33).
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
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.
Tab. 5: Secondary parameters
‰ The factory setting values are optimised thanks to auto-
matic parameters.
You can use these factory settings unchanged for most
welding jobs.
