List of set up parameters (TIG)
0 Save and quit
Allows you to save the changes and exit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
2 Pre-gas
Allows you to set and adjust the gas flow prior to striking
of the arc.

Allows setting of the time for which the initial current is
maintained.
Parameter setting: seconds (s).
Minimum off, Maximum 99.9s, Default off
6 Slope-up
Allows you to set a gradual passage between the initial
current and the welding current. Parameter set in sec-
onds (s).
Minimum off, Maximum 99.9s, Default off
7 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).

Minimum 3A-1%, Maximum Weld current-100%,
Default 50%
12 Pulsed frequency
Allows activation of the pulse mode.

14 Fast Pulse frequency
Allows regulation of the pulse frequency.
Allows focusing action and better stability of the elec-
tric arc to be obtained.
Parameter setting: KiloHertz (kHz).
Minimum 0.02KHz, Maximum 2.5KHz, Default off
15 Pulsed slopes
Allows setting of a slope time during the pulse operation.

current and the basic current, having a more or less soft
welding arc.
Parameter setting: percentage (%).
Minimum off, Maximum 100%, Default off
16 Slope-down

ing current and the final current.
