Parameters in the
TIG AC menu
Pulse frequency
off / 0.20 - 2000 Hz (10,000 Hz with FP Pulse Pro option)
Factory setting: off
IMPORTANT! If the pulse frequency is set to "off", the Base current and Duty cycle param-
eters cannot be selected.
The set pulse frequency is also used for the reduced current.
The pulse indicator in the status bar on the display lights up provided a value has been
specified for the pulse frequency.
FP Pulse Pro
To set the Base current and Duty cycle parameters
Base current
0 - 100% (of main current l
1
)
Factory setting: 50%
Duty cycle
Ratio of pulse duration to base current duration in cases where a pulse frequency has been
set
10 - 90%
Factory setting: 50%
Starting current time
(only in 2-step mode and during spot welding)
The starting current time specifies the duration of the starting current phase.
off / 0.01 - 30.0 s
Factory setting: off
IMPORTANT! The starting current time only applies to 2-step mode and spot welding. In
4-step mode, the duration of the starting-current phase is controlled using the torch trigger.
Final current time
(only in 2-step mode and during spot welding)
The final current time specifies the duration of the final current phase.
off / 0.01 - 30 s
Factory setting: off
IMPORTANT! The final current time only applies to 2-step mode and spot welding. In 4-
step mode, the duration of the final current phase is controlled using the torch trigger (see
"TIG operating modes").
