the set time, the machine will stop the wire in any mode in
which the button is pressed.

Options: (entering the code to unlock the optional
functions)
The machine leaves the factory with the lock function
active in the Double Lev. and JOB programs.
To
deactivate it, simply highlight and select it using knob B.
The display A shows 16 empty text boxes. To unlock,
enter a numeric alpha code in place of the zeros; this must
be requested from your dealer.
Once the code has been obtained, simply enter it in place
of the zeros: each letter or figure entered must be
confirmed by pressing the knob C. After entering the code,
by pressing the knob B this option is unlocked. After
confirming the selection made, to return to the previous
page press the knob B. If you want to go back to the main
menu, press the knob B again for at least 1 sec.

Double Level (LOCKED) Optional function.
Display A shows “OFF”. If key B is pressed, display A
shows the ON-OFF option. To activate the function, select
“ON” with knob C.
This type of welding makes the current intensity vary
between two levels. Before setting the double level
welding, make a short weld seam to determine the wire
speed and, consequently, the current required to obtain
optimal penetration and width of the seam for the joint to
be made. In this way, it is possible to determine the wire
feed speed (and thus the corresponding current). The set
metres per minute will be added to or deducted from this
value, alternatively.
Prior to execution, it should be remembered that in a
correct seam the overlapping between one “weld pass”
and the other must be at least 50%.
If the function is activated, the following abbreviations
appear in sequence:
-
Frequency
Adjustment from 0.1 Hz to 5.0Hz. Set with knob C. It
defines the frequency with which the welding current
passes from one level to another.
-
Pulse step
Adjustment from 0.1 m to 3.0.m. Set with knob C. It defines
the increase in speed in m/sec with which the wire exits,
and therefore the increase in current of the second level
with respect to the first.
-
Duty cycle
Adjustment from +25% to +75%. Set with knob C. It
defines the percentage in which the 2nd level is present in
the total time.
-
Arc corr.
Adjustment from -9.9V to +9.9V. Set with knob C. It
defines the voltage increase of the 2nd level with respect
to the 1st level.

Factory
The purpose is to return the welding machine to the
original default settings.
To access the function, simply highlight it using the knob B
and press it, the display screen A shows the words OFF
and ALL. To make the reset, highlight the word ALL and
press the knob B. After confirming the selection made, to
return to the previous page press the knob B. If you want
to go back to the main menu, press the knob B again for at
least 1 sec.

5.2 MIG WELDING WITHOUT GAS
The actions to prepare the welding machine for work are the
same as those described previously, but for this type of
welding proceed as follows:
Mount a coil of flux-cored wire for welding without gas.
Connect the power terminal of the torch coming out from
fairlead E to the negative pole socket G.
Connect the earth cable to the socket F and the earth clamp to
the workpiece.
Select the program suited for flux-cored wire. The program is
available only in MIG SHORT SYNERGIC and MIG MANUAL
processes.
5.3 WELDING WITH COATED ELECTRODES (MMA).
Before welding it is recommended to remove the MIG torch
and mount the electrode holder.
The electrode holder must (save for different indication by the
producer of the electrodes) be connected to the socket F
(positive polarity), and the earth cable to the negative polarity,
socket G.
VERY IMPORTANT: Connect the terminal of the earth cable
to the workpiece, making sure that contact is good to ensure
smooth equipment operation and avoid voltage dips with the
workpiece.
Turn on the welding machine.
To choose this process starting from the main menu press
knob B for at least 1sec. to enter the submenu. In the
submenu select Processes by turning and pressing the B
knob. In the Processes select MMA by turning and pressing
the B knob. To return to the submenu, press knob B again. To
return to the main menu, press and hold down knob B for at
least 1 sec.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- H. Start Time
- H. Start curr.
- A. Force curr.
To return to the previous screen, press knob B again. To
return to the main menu, press and hold down knob B for at
least 1 sec.
Do not touch the electrode clamp and the earth clamp
simultaneously.
Always remember to shut off the machine and remove the
electrode from the clamp after welding.
5.4 TIG WELDING
Before welding it is recommended to remove the MIG torch
and mount the TIG torch.
Connect the power terminal of the torch coming out from
fairlead E to the negative pole socket G.
Connect the earth cable connector to the positive pole socket
F, and the earth clamp to the workpiece as close as possible
to the welding point.
Connect the gas hose to the outlet of the pressure regulator of
an ARGON cylinder.
Use a 2% thorium-covered tungsten electrode (red strip),
diameter 1.6 ( 1/16” ).
Turn on the machine using the switch I.
To choose this process starting from the main menu press
knob B for at least 1sec. to enter the submenu. In the
submenu select Processes by turning and pressing the B
knob. In the Processes select TIG by turning and pressing the
B knob. To return to the submenu, press knob B again. To
return to the main menu, press and hold down knob B for at
least 1 sec.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- Start Mode
