CAUTION!
Risk of injury due to shock caused by electric shock
Although Fronius devices comply with all relevant standards, 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 scaffolding, work platforms, in forced
positions (out-of-position welding), in tight, difficult to access or exposed
areas!
Pri
Pre Ignition - delayed ignition with immediate high frequency start
Unit s
Setting range OFF / 0.1 - 1
Factory setting OFF
If a time value is set for the parameter Pri, the welding arc is ignited with a
delay corresponding to this value: Press the torch trigger - high frequency is
activated for the specified duration - the welding arc is ignited
I-2
Reduced current - Intermediate lowering of the welding current in order to
prevent any local overheating of the base material (4-step mode).
Unit % (of main current I
1
)
Setting range 0 - 100
Factory setting 50
ACF
AC frequency
Unit Hz
Setting range Syn / 40 - 250
Factory setting 60
Syn for mains synchronisation of two power sources for sim-
ultaneous AC welding.
IMPORTANT! In relation to the "Syn" setting, take account of the "PhA" para-
meter (phase adjustment in setup menu - level 2 AC/polarity reversal).
Low frequency soft, wide arc with shallow heat input
High frequency focused arc with deep heat input
FAC
Factory - for resetting the welding system
Press and hold the Store button for 2 s to reset the machine to the factory set-
tings. When the digital display shows "PrG", the welding system has been reset.
IMPORTANT! When the welding system is reset, all the personal settings in
the Setup menu are lost. Jobs are not deleted when the welding system is reset
- these are preserved. Welding parameter settings in setup menu - level 2 are
not deleted.
