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.
Permits filling of the torch with gas and preparation of
the environment for welding.
Minimum 0.0sec., Maximum 99.9sec., Default 0.1sec.
3 Initial current
Allows regulation of the weld starting current.
Allows a hotter or cooler welding pool to be obtained
immediately after the arc striking.
Parameter setting: Amperes (A) - Percentage (%).
Minimum 3A-1%, Maximum Imax-500%, Default 50%
5 Initial current time
Allows setting of the time for which the initial current is
maintained.
Parameter setting: seconds (s).
Minimum off, Maximum 99.9s, Default off
44
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, Maximum Imax, Default 100A
8 Bilevel current
Permits adjustment of the secondary current in the
bilevel welding mode.
On first pressing the torch button, the pre-gas starts,
the arc strikes and the initial current will be used when
welding.
On first releasing it, the raising ramp of the welding current
"I1" occurs. If the welder now presses and releases the
button quickly, "I2" can be used; by pressing and releasing
it quickly again, "I1" is used again, and so on.
If you press the button for a longer time, the lowering ramp
for the current starts, thus reaching the final current.
By releasing the button again, the arc goes out and the
gas continues to flow for the post-gas stage.
Parameter setting: Amperes (A) - Percentage (%).
Minimum 3A-1%, Maximum Imax-500%, Default 50%
10 Basic current
Permits adjustment of the basic current in pulsed and
fast pulse modes.
Parameter set in Amps (A).
Minimum 3A-1%, Maximum Weld current-100%,
Default 50%
12 Pulsed frequency
Allows activation of the pulse mode.
Allows regulation of the pulse frequency.
Allows better results to be obtained in the welding of
thin materials and better aesthetic quality of the bead.
Parameter setting: Hertz (Hz) - KiloHertz (kHz).
Minimum 0.1Hz, Maximum 250Hz, Default off
13 Pulsed duty cycle
Allows regulation of the duty cycle in pulse welding.
Allows the peak current to be maintained for a shorter
or longer time.
Parameter setting: percentage (%).
Minimum 1%, Maximum 99%, Default 50%
14 Fast Pulse frequency
Allows regulation of the pulse frequency.
Allows focusing action and better stability of the electric
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.
Allows a smooth step to be obtained between the peak
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
Allows you to set a gradual passage between the weld-
ing current and the final current.
Parameter set in seconds (s).
Minimum off, Maximum 99.9s, Default off
17 Final current
Permits adjustment of the final current.
Parameter set in Amps (A).
Minimum 3A-1%, Maximum Imax-500%, Default 10A
