Cellulose, Aluminium
P = C* Constant power
The increase in arc length causes a reduction in the
welding current (and vice versa) according to the law:
V.I = K.
Cellulose, Aluminium
* Increasing the value of the arc force to reduce the risks
of sticking of the electrode.
312 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various oper-
ating conditions that occur. In the spot welding phase,
for example, a low arc detachment voltage reduces
re-striking of the arc when moving the electrode away
from the piece, reducing spatter, burning and oxidisa-
tion of the piece.
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Parameter set in Volts (V).
Minimum 0V, Maximum 99.9V, Default 57V
500 Allows the selection of the required graphic interface:
XE (Easy Mode)
XA (Advanced Mode)
XP (Professional Mode)
Allows access to the higher set-up levels:
USER: user
SERV: service
vaBW: vaBW
551 Lock/unlock
Allows the locking of the panel controls and the insertion
of a protection code (consult the "Lock/unlock" section).
552 Buzzer tone
Permits adjustment of the buzzer tone.
Minimum Off, Maximum 10, Default 10
553 Contrast (LCD 4.7")
Permits adjustment of the display contrast.
Minimum -20, Maximum +20
601 Adjustment step
Permits adjustment of the variation step on the up-
down keys.
Minimum Off, Maximum MAX, Default 1
602 CH1 External parameter
Allows the management of external parameter 1 (mini-
mum value, maximum value).
(Consult the "External controls management" section).
751 Current reading
Allow the real value of the welding current to be dis-
played.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
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
6 Slope-up
Allows you to set a gradual passage between the initial cur-
rent and the welding current. Parameter set in seconds (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%
