103 (TIG AC) AC balance
Allows regulation of the duty cycle in TIG AC welding.
Allows the positive polarity to be maintained for a
longer or shorter time.
Parameter setting: percentage (%).
Minimum 15%, Maximum 65%, Default 35%
104 (TIG AC) Fuzzy logic
Allows regulation of the power delivered by the system
during the arc striking phase by selecting the electrode
diameter used.
Makes it possible to suitably heat the electrode and/or
to keep the tip intact.
Parameter setting: millimetres (mm).
Minimum 0.1mm, Maximum 5.0mm, Default 2.4mm
105 Easy rounding
Allows a greater amount of energy to be delivered dur-
ing the TIG AC arc striking phase.
Allows the rounding of the electrode in a uniform and
regular manner.
The function is automatically disabled after the arc has been struck.
The power delivered depends on the electrode diam-
eter set on the fuzzy logic.
Default off
107 AC - DC time mix
Allows adjustment of the welding time in direct current
when the AC MIX function is enabled.
Parameter setting: seconds (s).
Minimum 0.02s, Maximum 2.00s, Default 0.24s
108 AC - AC time mix
Allows regulation of the welding time in alternating cur-
rent when the AC MIX function is enabled.
Parameter setting: seconds (s).
Minimum 0.02s, Maximum 2.00s, Default 0.24s
109 (DC) Welding current
Allows adjustment of the welding current in direct cur-
rent when the AC MIX function is enabled.
Parameter setting: percentage (%).
Minimum 1%, Maximum 200%, Default 100%
203 TIG start (HF)
Allows selection of the required arc striking modes.
On= HF START, Off= LIFT START, Default HF START
204 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
205 Restart
Allows the activation of the restart function.
Allows the immediate extinguishing of the arc during
the down slope or the restarting of the welding cycle.
0=Off, 1=On, Default On
206 (TIG DC) Easy joining
Allows striking of the arc in pulsed current and timing of
the function before the automatic reinstatement of the
pre-set welding conditions.
Allows greater speed and accuracy during tack welding
operations on the parts.
Parameter setting: seconds (s).
Minimum 0.1s, Maximum 25.0s, Default off
207 (TIG AC) Extra energy
Allows balancing of the current in positive polarity com-
pared with that in negative polarity.
Makes it possible to obtain greater cleanness of the base
material or greater welding capacity while keeping the
average current value unchanged.
Parameter setting: percentage (%).
Minimum 1%, Maximum 200%, Default 100%
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 inser-
tion of a protection code (consult the "Lock/unlock"
section).
552 Buzzer tone
Permits adjustment of the buzzer tone.
Minimum Off, Maximum 10, Default 5
553 Contrast
Permits adjustment of the display contrast.
Minimum 0, Maximum 50
601 (U/D) Adjustment step
Permits adjustment of the variation step on the up-
down keys.
Minimum Off, Maximum MAX, Default 1
602 CH1, CH2, CH3, CH4 External parameter
Allows the management of external parameter 1 (mini-
mum value, maximum value, default value, parameter
selected).
(Consult the "External controls management" section).
606 U/D torch
Allows the management of the external parameter
(U/D). 0=Off, 1=A
751 Current reading
Allow the real value of the welding current to be dis-
played.
Allows the welding current display method to be set.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
Allows the welding voltage display method to be set.
755 Gas flow reading
Allows the real gas flow value to be displayed.
Allows the setting of the gas flow display method.
757 Wire speed reading
760 (Motor) Current reading
Allow the real value of the (motor) current to be dis-
played.
801 Guard limits
Allows the setting of the warning limits and of the guard
limits.
Allows the accurate control of the various welding
phases (consult the "Guard limits" section).
851 ARC-AIR enabling
On=Active, Off=No active
