- ”A.8” : Auxiliary voltage out of range.
Upon switching off of the welding machine, the ”OFF” signalling could continue
for several seconds.
N.B.:ALARMSSTORAGEANDDISPLAY
With every alarm the machine’s setting are stored. It is possible to recall the last
10 alarms as follows:
Press pushbutton (6a) “REMOTE COMMAND” for a few seconds
Code “AY.X” is displayed, where “Y” indicates the alarm number (A0 most recent,
A9 oldest) and “X” indicates the type of alarm recorded (from 1 to 8, see AY.1 ...
AY.8).
12- Green led, power on.

1- Positive quick latch (+) to connect the welding cable.
2- Negative quick latch (-) to connect the welding cable.
3- Connector for cable connection of the TIG torch button (FIG. D2-a) and TIG
controller (FIG. D2-b).
4- Fitting for connecting the gas pipe of the TIG torch.
5- Controls panel.
6- Welding modes selection pushbuttons:
6a
REMOTE COMMAND
Allows the transfer of the control of the welding parameters to the remote
control.
6b
TIG - MMA
Operating mode: coated electrode welding (MMA), TIG welding with contact
arc lift strike (TIG HF) and TIG welding with contact arc lift strike (TIG LIFT).
6c
AC/DC
In TIG mode it allows selection between direct current (DC) welding and
alternate current (AC) welding (function present only on AC/DC models).
6d
2T-4T-SPOT
In TIG mode it allows selection between 2-stroke or 4-stroke command, or with
spot welding timer (SPOT).
6e
PULSE-PULSEEASY-BiLEVEL
In TIG mode the operator can choose between pulse, easy pulse or bi-level
pulse welding processes. The LEDs are OFF when the machine is in standard
welding mode.
7- Pushbuttonfortheselectionofparameterstobeset.
Pushbutton selects the parameter to be adjusted through the Encoder knob (9);
the value and unit of measure are shown respectively on display (10) and led (11).
N.B.: The setting of parameters is free. Nevertheless, there are value combinations
that don’t have any practical meaning for the welding; in this case the welding
machine could operate incorrectly.
N.B.:RE-SETTINGOFALLFACTORYPARAMETERS(RESET)
Press all buttons (8) together at start-up to reset the welding parameters to default
settings.
7a
PRE-GAS
In TIG/HF mode it represents the PRE-GAS time in seconds (adjustment
range from 0÷5 seconds). It improves the welding start.
7b
START CURRENT (I
START
)
In TIG 2-stroke and SPOT modes this represents the start current I
S
maintained
for a set time with the torch button pressed (regulation in Ampere).
In 4-stroke TIG mode it represents the initial current Is maintained for the
whole time during which the torch pushbutton is pressed (adjustment in
Amperes).
In MMA mode it represents the “HOT START” dynamic over-current
(adjustment range 0÷100%) with indication on display of the percentage
increase in relation to the value of the pre-selected welding current. This
adjustment improves the weld uidity.
7c
INITIAL SLOPE (t
START
)
In TIG mode this represents the start current slope up time (from I
S
to I
2
)
(adjustment 0.1÷10sec.). The slope is no present when switched OFF.
The I
START
and t
START
parameters can be used even with the pedal remote
control, but must be adjusted before activating the control itself.
7d
MAIN CURRENT (I
2
)
In TIG AC/DC and in the MMA modes, it represents the output current I
2
. In
PULSED and in BI-LEVEL modes it is the highest level current (maximum).
The parameter is measured in Amperes.
7e
BASE CURRENT - ARC FORCE
In 4-stroke TIG in the BI-LEVEL and in PULSED modes, I
1
represents the
value of the current, which can be alternated to the main I
2
during welding. The
value is expressed in Amperes.
In MMA mode, it represents the “ARC-FORCE” dynamic over-current
(adjustment range 0÷100%) with indication on display of the percentage
increase in relation to the value of the pre-selected welding current. This
adjustment improves the weld uidity and avoids the electrode sticking to the
piece being welded.
7f
FREQUENCY
In PULSED TIG mode, it represents the pulsing frequency. For the AC/DC models, in
the TIG AC mode (with pulsing disabled) it represents the welding current’s frequency.
7g BALANCE
When in the TIG PULSED mode, this is the ratio (as a percentage) between
the time during which the current is at its highest level (main welding current)
and the total pulse period. In addition, when the AC/DC models are in the
TIG AC mode (with pulsation disabled), the parameter represents a ratio
between the time with positive current and the time with negative current: if
the parameter value is negative heating and workpiece penetration increase, if
the parameter value is positive surface cleaning is greater and electrode heat
increases, while if the parameter value is null there is balance between the
negative and positive currents during the AC frequency period. (TAB.4).
7h
SPOT TIME
In TIG (SPOT) mode, it represents the duration of the welding (adjustment
range 0.1÷10sec.).
7k
END SLOPE (t
END
)
In TIG mode this represents the nal current slope down time (from I
2
a I
e
)
(adjustment 0.1÷10sec.). The slope is not present when switched OFF.
7l
END CURRENT (I
END
)
In TIG 2-stroke mode, it represents the end current I
e
only if the END SLOPE
(7k) is set on a value greater than zero (>0.1 sec.).
In TIG 4-stroke mode, it represents the end current I
e
for the whole time during
which the torch pushbutton is pressed.
Magnitudes are expressed in Amperes.
7m
POSTGAS
In TIG mode, it represents the POSTGAS time in seconds (adjustment range
0.1÷25sec.) and protects the electrode and the weld pool from oxidation.
7n
ELECTRODE PREHEATING
In TIG mode, AC represents the result of the current multiplied by the Tungsten
electrode preheating time from when the arc is switched on.
