CAUTION!
Risk of injury due to an electric shock
Although Fronius devices comply with all relevant standards, the high frequency ignition
can transmit a harmless but noticeable electric shock under certain circumstances.
► Use prescribed protective clothing, especially gloves!
► Only use suitable, completely intact and undamaged TIG hosepacks!
► Do not work in damp or wet environments!
► Take special care when working on scaffolds, work platforms, in forced positions, in
tight, difficult to access or exposed places!

This menu item can be used to hide the pulsing and tacking parameters on the control pan-
el in the welding parameter overview.
Ignition time out
Period of time until the safety cut-out following failed ignition
0.1 - 9.9 s
Factory setting: 5 s
Arc break monitoring
Period of time until the safety cut-out following an arc break
0.1 - 9.9 s
Factory setting: 1.0 s
IMPORTANT! Arc break monitoring is a safety function and cannot be deactivated.
A description of the arc break monitoring function can be found in the "TIG Welding" sec-
tion on page 61.
TIG Comfort Stop sensibility - comfort stop sensitivity
The parameter is only available if the "Trigger" parameter is set to "off".
oFF / 0.6 - 3.5 V
Factory setting: 1.5 V
At the end of the welding process, an automatic shutdown of the welding current follows a
significant increase of the arc length. This prevents the arc from having to be unnecessarily
lengthened when lifting the TIG welding torch.
