99 Reset
Allows you to re-set all the parameters to the default
values and restore the whole system to the conditions
predefined.
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 25sec., 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%
4 Initial current (%-A)
0=A, 1=%, Default %
5 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 10s, Default off
6 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%
7 Bilevel current (%-A)
Permits adjustment of the secondary current in the
bilevel welding mode.
0=A, 1=%, 2=Off
The TIG bilevel, when enabled, replaces the 4-stage
mode.
8 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%
9 Base current (%-A)
Permits adjustment of the base current in pulsed and
fast pulse modes.
Parameter setting: Amperes (A) - Percentage (%).
0=A, 1=%, Default %
10 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 0.5Hz, Maximum 20Hz, Default off
11 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%
12 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 20KHz, Maximum 500KHz, Default off
13 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 10s, Default off
14 Final current
Permits adjustment of the final current.
Parameter set in Amps (A).
Minimum 3A-1%, Maximum Imax-500%, Default 50%
15 Final current (%-A)
Permits adjustment of the final current.
Parameter setting: Amperes (A) - Percentage (%).
0=A, 1=%, Default %
16 Post-gas
Permits setting and adjustment of the gas flow at the
end of welding.
Minimum 0.0s, Maximum 25s, Default syn (0.0)
17 Start current (HF start)
Parameter setting: Amperes (A).
Minimum 3A, Maximum Imax, Default 100A
18 Tig start (HF or LIFT)
Allows selection of the required arc striking modes.
1=LIFT START, 0= HF START, Default HF START
19 Spot welding
Allows you to enable the "spot welding" process and
establish the welding time.
Allows the timing of the welding process.
Parameter setting: seconds (s).
Minimum off, Maximum 99.9s, Default off
40 Measurements
Permits selection of the type of measurement to be
shown on the display 4.
0 Real current
1 Real voltage
2 No measurement
Default 0
41 Machine ventilation start temperature
Minimum 0°C, Maximum 39°C, Default 25°C
99 Reset
Allows you to re-set all the parameters to the default
values and restore the whole system to the conditions
predefined.
