- MMAwelding:
- “Arc Force” adjustable to select the best dynamic char-
acteristics for the welding arc.
- “Hot Start” adjustable to improve ignition with particu-
larly difficult electrodes.
- Anti-sticking function to avoid the electrodes sticking.
- Vrd (Voltage Reduction Device), which makes it pos-
sible to use the welding power source in environments
where the risk of electric shock or electrocution caused
by arc welding is enormously increased by the pres-
ence of water, humidity, or heat, and particularly where
the ambient temperature exceeds 32°C.
- TIG welding:
- “Lift” type ignition, with TCS “Thermal Control Start” de-
vice to further reduce tungsten inclusions.
- Exclusive SWS “Smart Welding Stop” system at the
end of TIG welding. Lifting up the torch without switch-
ing off the arc will introduce a SLOPE DOWN and it will
switch off automatically.
Technical data
The general technical data of the system are summarized in
table 1.
Usage limits (IEC 60974-1)
The use of a welder is typically discontinuous, in that it is made
up of effective work periods (welding) and rest periods (for the
positioning of parts, the replacement of wire and underflush-
ing operations etc. This welder is dimensioned to supply a I
2
max nominal current in complete safety for a period of work of
X% of the total usage time. The regulations in force establish
the total usage time to be 10 minutes. The work cycle is con-
sidered to be X% of this period of time. When the work cycle
permitted is exceeded a trip switch trips, which protects the
welding welding power source’s internal components against
dangerous overheating and prevents incorrect functioning of
the welding power source. After several minutes the overheat
cut-off rearms automatically and the welder is ready for use
again (Automatic reset error). This equipment is built to have
a protection level of IP 23 S, which means:
•
That it is protected against the penetration of solid foreign
bodies with diameters in excess of Ø 12 mm.
•
That it is protected against water spray hitting the surface
with an angle of incidence up to 60°.
• That the equipment has been tested for withstanding harm-
ful effects due to water getting in when the moving parts on
the equipment are moving.

How to lift up the welding power source
The welding power source has a strong handle all in one with
the frame, used for transporting the welding power source man-
ually only.
NOTE: These hoisting and transportation devices conform to
European standards. Do not use other hoisting and transpor-
tation systems.
Open the packaging
Upon receiving the welding power source:
•
Remove the welding power source and all relevant accesso-
ries-components from their packaging.
• Check that the welding power source is in good condition, if
not report any problems immediately to the seller-distributor.
• Make sure all ventilation grilles are open and that no foreign
bodies are blocking the air circulation.
Installation and connections
The installation site for the system must be carefully chosen
in order to ensure its satisfactory and safe use. The user is re-
sponsible for the installation and use of the system in accord-
ance with the producer’s instructions contained in this manual.
Before installing the system the user must take into consider-
ation the potential electromagnetic problems in the work area.
In particular, we suggest that you should avoid installing the
system close to:
• Signalling, control and telephone cables.
• Radio and television transmitters and receivers.
• Computers and control and measurement instruments.
• Security and protection instruments.
Persons fitted with pace-makers, hearing aids and similar
equipment must consult their doctor before going near a weld-
ing power source in operation. The equipment’s installation
environment must comply to the protection level of the frame
i.e. IP 23 S (IEC 60529 publication). The system is capable of
working in environments where working conditions are partic-
ularly hard.
This system is cooled by means of the forced circulation of air,
and must therefore be placed in such a way that the air may
be easily sucked in and expelled through the apertures made
in the frame.
The equipment must be assembled as follows:
• Mount on the trolley (optional extra).
• Fix the welding unit to the trolley.
• Connect the welding welding power source to the utility line.
• Connect up the welding cables.
Connecting the welding welding
power source to the utility line
Connection of the welding power source to the user line
(electrical current) must be performed by qualified per-
sonnel.
Before connecting the welding welding power source to
the mains power supply, make sure that rated voltage and
frequency correspond to those provided by the mains pow-
er supply and that the welding welding power source’s
power switch is turned to “O”.
Connection to the power supply must be carried out using the
tripolar cable supplied with the system, of which:
•
2 conducting wires are needed for connecting the welding
power source to the supply.
•
The third, which is YELLOW GREEN in colour is used for
making the “GROUND” connection.
Connect a suitable load of normalised plug (2p + e) to the
power cable and provide for an electrical socket complete
with fuses or an automatic switch. The ground terminal
must be connected to the ground conducting wire (YEL-
LOW-GREEN) of the supply.
Table 2 shows the capacity values that are recommended for
fuses in the line with delays.
NOTE: Any extensions to the power cable must be of a suita-
ble diameter, and absolutely not of a smaller diameter than the
special cable supplied with the welding power source.

• Thread the end of the wire into the back guide (Pos. 7, Fig.
B) on the drawing mechanism.
• Lift up the idle roller Ø 26 mm (Pos. 1, Fig. B) releasing the
roller pressure mechanism (Pos. 6, Fig. B). Check that the
drive roller (Pos. 4, Fig. B) has the diameter corresponding
to the wire being used printed on the outer side.
• Thread the wire into the central wire guide and into the wire
guide of the centralized attachment (Pos. 3, Fig. B) for a few
centimetres. Lower the idle roll-holder arm making sure the
wire goes into the slot of the drive roll. If necessary, adjust the
pressure between the rollers with the screw provided (Pos.
5, Fig. B). The correct pressure is the minimum that does not
allow the rollers to skid on the wire. Excessive pressure will
case deformation of the wire and tangling on the entrance of
the sheath; insufficient pressure can cause irregular welding.
Assembly of drive roller
Follow instructions given below for mounting the drawing roll-
er onto the mechanism:
• Unscrew the screw (Pos. 5, Fig. B).
• Lift up the idle roll-holder arm Ø 26 mm (Pos. 2, Fig. B).
•
Each roller shows the type of wire and diameter on the two
external sides.
•
Mount the appropriate roller (Pos. 4, Fig. B) making sure the
groove is in the right position for the diameter of the wire be-
ing used.
• Screw the screw (Pos. 5, Fig. B).
MIG-MAG / Puls MIG / DOUBLE
Puls MIG welding with GAS
To begin MIG-MAG / Puls MIG / DOUBLE Puls MIG welding,
carry out the following tasks (with the welding power source
switched off):

6
1 - Connecting the cables (Fig. C1-C2)
1) Connect the gas hose to the pressure reducer fitted on
the cylinder beforehand. Gas cylinders are supplied with
a pressure reducer to adjust pressure of the gas used for
welding.
2) Screw the torch to the centralised connection on the front
panel of the welding welding power source (Pos. 4, Fig.A).
3) Connect up the earthing system cable to the rapid cou-
pling marked by a - (negative) symbol and then the rel-
evant ground clamps to the piece being welded or to its
support in an area free from rust, paint and grease. Using
particularly long earthing cables reduces the voltage and
causes some problems from increased resistance and in-
ductance of the cables that could cause faulty welding. Fol-
low instructions to avoid these problems:
•
Use earthing and extension cables with appropriate sec-
tion.
• Lay out the cables as a flat as possible to prevent them
from coiling up.
4) Open the moving cover, remove the protection box for
changing polarity (see Fig. C2) and make sure that the
change polarity cable is connected to the positive pole (+).
2 - Welding
1) Open the moving cover and fit the coil of wire.
2) Load the wire (see the “Loading the wire” paragraph).
3) Switch the welding welding power source on by moving the
power supply switch to I(Pos. 5, Fig. A).
4) Carry out the following operations on the MIG-MAG torch:
• Remove the gas-guide and wire-guide nozzles, allowing
the wire to flow freely during loading. Remember that the
contact tip must correspond to the wire diameter.
•
Push the torch push button or the motor check push but-
ton until the wire end comes out from the torch.
• Tighten the contact tip on the torch.
• Attach the correct gas-guide nozzle.
• Protect the gas-guide nozzle and the wire-guide nozzle
of the torch from sprays of solder.
5) Make the adjustments and select the parameters on the
control panel.
6) Open the tap on the cylinder slowly and adjust the reduc-
er knob to obtain a pressure of about 1,0 to 1,5 bar, and
regulate the flow to about 15 lit/min (to suit the current to
used for welding).
7) The welding welding power source is ready for welding. To
begin welding, approach the point to be welded and press
the button on the torch.
8) When you have finished welding, remove the waste, turn
off the welding power source and close the gas cylinder.

1 - Connecting the cables (Fig. D1-D2)
1) Screw the torch to the centralised connection on the front
panel of the welding welding power source (Pos. 4, Fig.A).
2) Connect up the earthing system cable to the rapid cou-
pling marked by a + (positive) symbol and then the relevant
ground clamps to the piece being welded or to its support in
an area free from rust, paint and grease. Using particularly
long earthing cables reduces the voltage and causes some
problems from increased resistance and inductance of the
cables that could cause faulty welding. Follow instructions
to avoid these problems:
•
Use earthing and extension cables with appropriate sec-
tion.
• Lay out the cables as a flat as possible to prevent them
from coiling up.
3) Open the moving cover, remove the protection box for
changing polarity (see Fig. D2) and move the change po-
larity cable, connecting it to the negative pole (-).
2 - Welding
1) Open the moving cover and fit a coil of wire with a core for
welding without using gas.
2) Load the wire (see the “Loading the wire” paragraph).
3) Switch the welding welding power source on by moving the
power supply switch to I(Pos. 5, Fig. A).
4) Carry out the following operations on the MIG-MAG torch:
• Remove the gas-guide and wire-guide nozzles, allowing
the wire to flow freely during loading. Remember that the
contact tip must correspond to the wire diameter.
•
Push the torch push button or the motor check push but-
ton until the wire end comes out from the torch.
• Tighten the contact tip on the torch.
• Attach the correct gas-guide nozzle.
• Protect the gas-guide nozzle and the wire-guide nozzle
of the torch from sprays of solder.
5) Make the adjustments and select the parameters on the
control panel. Make sure that you have selected a program
that is suitable for wire with a core.
6) The welding welding power source is ready for welding. To
begin welding, approach the point to be welded and press
the button on the torch.
7) Once welding has been completed remove the slag and
switch off the welding power source.
Spot welding
FIG. E
Welding can be done with or without gas.The substantial differ-
ence with MIG-MAG welding is essentially related to the torch
and the adjustments that must be made on the control panel.
• Depending on the torch chosen and the work to be done, a
gas guide nozzle can be fitted on the torch that is specifical-
ly for spot welding (see Fig. E).
• Use the control panel to select the spot-welding mode and,
if necessary, make the changes to the related “Special func-
tions - Fx” (for further information see the control panel manu-
al), which allows the welding power source to do this specific
type of welding.
To begin spot welding:
•
Place the gas guiding nozzle perpendicular on the workpiece
to be spot welded.
•
Press the torch button to start the welding current and wire
feed.
•
When the spot welding time expires (SPOT WELD TIME),
the wire feed stops automatically.
•
When the torch button is pushed again a new welding cy-
cle starts.
FIG. D1
FIG. D2
2000HB99

FIG. F
• Release the torch button.
Interval welding (Stitch)
The substantial differences with the spot welding mainly con-
cern the adjustments that must be carried on the welding weld-
ing power source.
Use the control panel to select the interval welding mode and
then make the changes to the related “Special functions - Fx”,
which allows the welding power source to do this specific type
of welding.
To begin interval welding:
•
Press the torch button to start the welding current and wire
feed.
•
At this point the welding welding power source automatically
carries out a succession of welded portions (STITCH WELD
TIME) followed by a pause (STITCH WELD PAUSE), ac-
cording to the times entered previously. This procedure stops
automatically only when the TORCH BUTTON is released.
•
When the torch button is pushed again the torch begins a
new interval welding cycle.
Aluminium welding
To weld with aluminum wire proceed as follows:
•
Replace the drive roller with the appropriate for aluminum
wire.
•
We recommend to use a torch set with maximum lenght of
3 m and a capillary liner, e.g. DIX DSK 2-xx..
•
Set the pressure between the drive rollers at the minimum,
by turning the screw provided.
• Use argon gas at a pressure of 1,3 - 1,7 bar.
TIG welding with “Lift”
In the TIG process welding is achieved by melting the two met-
al pieces to be joined, with the possible addition of material
from the outside, using an arc ignited by a tungsten electrode.
The “Lift” (TCS) type ignition used in TREOSTAR equipments
makes it possible to reduce tungsten inclusions on ignition to a
minimum. The molten bath and the electrode are protected by
and inert gas (for example,Argon). This type of welding is used
to weld thin sheet metal or when elevated quality is required.
1) Connecting the welding cables (Fig. F):
• Connect one end of the gas hose to the gas connecter on
the TIG torch and the other end to the pressure reducer
on the inert gas cylinder (Argon or similar).
• With the welding power source switched off:
- Connect the ground cable to the snap-on connector
marked + (positive).
- Connect the relative ground clamp to the workpiece or
to the workpiece support in an area free of rust, paint,
grease, etc..
- Connect the TIG torch power cable to the snap-on con-
nector marked - (negative).
2) Switch the welding welding power source on by moving the
power supply switch to I(Pos. 5, Fig. A).
3) Make the adjustments and do the parameter settings on
the control panel.
4) Open the gas cylinder and regulate the flow by adjusting
the valve on the TIG torch by hand.
5) Ignite the electric arc by contact, using a decisive, quick
movement without dragging the tungsten electrode on the
piece to be welded (“Lift” type ignition - Fig. G).
6) The welder has a SWS “Smart Welding Stop” system for
the end of TIG welding. Lifting up the torch without switch-
ing off the arc will introduce a slope down and it will switch
off automatically.
7) When you have finished welding remember to shut the
valve on the gas cylinder.
Table 3 shows the currents to use with the respective elec-
trodes for TIG DC welding. This input is not absolute but is for
your guidance only; read the electrode manufacturers’instruc-
tions for a specific choice. The diameter of the electrode to use
is directly proportional to the current being used for welding.

Electrode welding (MMA)
Electrode welding is used to weld most metals (different types
of steel, etc.) using coated rutilic and basic electrodes with di-
ameters ranging from Ø 1.6 mm to Ø 3,2 mm.
1) Connecting the welding cables (Fig. H):
Disconnect the welding power source from the mains pow-
er supply and connect the welding cables to the output
terminals (Positive and Negative) of the welding welding
power source, attaching them to the clamp and ground
FIG. G
2000HA86

with the polarity specified for the type of electrode being
used (Fig. H). Always follow the electrode manufacturer’s
instructions. The welding cables must be as short as pos-
sible, they must be near to one another, positioned at or
near floor level. Do not touch the electrode clamp and the
ground clamp simultaneously.
2) Switch the welding welding power source on by moving the
power supply switch to I(Pos. 5, Fig. A).
3) Make the adjustments and select the parameters on the
control panel .
4) Carry out welding by moving the torch to the workpiece.
Strike the arc (press the electrode quickly against the met-
al and then lift it) to melt the electrode, the coating of which
forms a protective residue. Then continue welding by mov-
ing the electrode from left to right, inclining it by about 60°
compared with the metal in relation to the direction of weld-
ing.
PART TO BE WELDED
The part to be welded must always be connected to ground
in order to reduce electromagnetic emission. Much attention
must be afforded so that the ground connection of the part to
be welded does not increase the risk of accident to the user or
the risk of damage to other electric equipment. When it is nec-
essary to connect the part to be welded to ground, you should
make a direct connection between the part and the ground
shaft. In those countries in which such a connection is not al-
lowed, connect the part to be welded to ground using suitable
capacitors, in compliance with the national regulations.
WELDING PARAMETERS
Table 4 shows some general indications for the choice of elec-
trode, based on the thickness of the parts to be welded. The
values of current to use are shown in the table with the respec-
tive electrodes for the welding of common steels and low-grade
alloys. These data have no absolute value and are indicative
data only. For a precise choice follow the instructions provided
by the electrode manufacturer.

The current to be used depends on the welding positions and
the type of joint, and it increases according to the thickness and
dimensions of the part.
The current intensity to be used for the different types of weld-
ing, within the field of regulation shown in table 5 is:
• High for plane, frontal plane and vertical upwards welding.
• Medium for overhead welding.
•
Low for vertical downwards welding and for joining small pre-
heated pieces.

Afairly approximate indication of the average current to use in
the welding of electrodes for ordinary steel is given by the fol-
lowing formula: I = 50 × (Øe - 1)
Where:
I = intensity of the welding current
Øe = electrode diameter
Example:
For electrode diameter 4 mm
I = 50 × (4 - 1) = 50 × 3 = 150A
Maintenance
ATTENTION: Cut off the power supply to the equipment be-
fore effecting any internal inspection.
DIX PI GO 1156.M Puls
IMPORTANT: Since the welding welding power sources are ful-
ly electronic, removing the dust that is sucked into the welding
power source by the fans, is of utmost importance.
In order to achieve correct functioning of the welding power
source, proceed as described:
•
Periodic removal of accumulations of dirt and dust inside the
equipment using compressed air. Do not point the jet of air
directly at the electrical parts as this could damage them.
•
Periodical inspection for worn cables or loose connections
that could cause overheating.
•
Make sure the air circuit is completely free of any impuri-
ties and that the connections are tight and free of any leaks.
In this connection, inspect the solenoid valve very carefully.
•
Check the wire feeder rolls periodically and replace them
when wear impairs the regular flow of the wire (slipping etc).
TORCH
The torch is subjected to high temperatures and is also stressed
by traction and torsion. We recommend not to twistthe wire and
not to use the torch to pull the welder. As a result of the above
the torch will require frequent maintenance such as:
• Cleaning welding splashes from the gas diffuser so that the
gas flows freely.
• Substitution of the contact point when the hole is deformed.
•
Cleaning of the wire guide liner using trichloroethylene or
specific solvents.
• Check of the insulation and connections of the power cable;
the connections must be in good electrical and mechanical
condition.
SPARE PARTS
Original spares have been specifically designed for our equip-
ment. The use of spares that are not original may cause vari-
ations in the performance and reduce the safety level of the
equipment. We are not liable for damage due to use of spare
parts that are not original.

The pointing out of any difficulties
and their elimination
The supply line is attributed with the cause of the most com-
mon difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage.
2) Check that the power cable is perfectly connected to the
plug and the supply switch.
3) Check that the power fuses are not burned out or loose.
4) Check whether the following are defective:
• The switch that supplies the welding power source.
• The plug socket in the wall.
• The generator switch.
NOTE: Given the required technical skills necessary for the re-
pair of the generator, in case of breakdown we advise you to
contact skilled personnel or our technical service department.
Replacing the digital interface PCB
Proceed as follows:
• Unscrew the 4 screws that fix the front rack panel.
• Remove both the adjustment knobs.
• Disconnect the electrical connectors for the board.
• Unscrew the support columns.
• Remove the electronic board by lifting it off its supports.
• To fit a new board, follow this procedure in reverse.

2) Pressing and releasing the TORCH TRIGGER will start the
welding cycle.
CRATER 2T
2T LED ( ) switched on - CRATER LED ( ) switched on
1) When theTORCHTRIGGER is pushed the arc ignites and the
parameters assume the values for the “initial crater” for a time
set by means of the CRATER START TIME (F10) function.
After that the parameter values become those for “welding” for
a time defined by the CRATER STARTSLOPE (F11) function.
2) When the TORCH TRIGGER is released the parameters take
on the “final crater” values for a time set by means of the CRA-
TER END TIME (F15) function, for a period of time set using
the CRATER END SLOPE (F12) function.

To begin stitch welding:
1) Press the TORCHTRIGGER to start the welding current and
wire feed.
At this point the welder will perform automatically a succession
of a welded tracts followed by a pause, respecting the times
set in the functions STITCH WELD TIME (F05) and STITCH
WELD PAUSE (F06).
This procedure stops automatically only when the TORCH
TRIGGER is released.
2) When the TORCH TRIGGER is pushed again the torch be-
gins a new interval welding cycle.
SWITCH mode
4T LED ( ) switched on - CRATER LED ( ) flashing
1) When the TORCH BUTTON is pushed, the arc is ignited and
the welding parameters take on the values for the initial cra-
ter.
2) When the TORCH BUTTON is released, the current goes to
that for welding at a time defined by the CRATER START
SLOPE function (F11).
3) When the SWITCH BUTTON is pressed and released within
1 second, the current goes to that defined by the (F19) and
(F20) “SWITCH” functions. By repeating this operation, you
can switch an infinite number of times between the I2 level
and welding level.

welding parameter has been selected.
■PROGRAMME SELECTION LED
This LED will be lit only when the operator selects a welding pro-
cess (in which there welding programmes present) and the rela-
tive associated programme.
■PARAMETER DISPLAY screen - A
This Display shows the values / numbers (set or measured) of the
following parameters (if active):
• THICKNESS OF WELDED ITEM ( ).
• WELDING CURRENT ( ).
• WIRE SPEED ( ).
• WELDING PROGRAM ( ).
■HOLD FUNCTION LED
Flashing, it indicates that the values of the parameters views on
the PARAMETER DISPLAY -Aand V are respectively the values
that are set or measured at the conclusion of the last welding. The
LED flashes for 15 seconds consecutively before turning itself off or
until the moment that the operator varies any parameter by means
of the use of the handles.
■WELDING PROCESS SELECTION LED

■Fx LED - SPECIAL FUNCTIONS
Switched on when special Fx parameters are displayed.
■VRD LED
The Voltage Reduction Device (VRD) is a safety device that re-
duces voltage. It prevents voltages forming on the output termi-
nals that may pose a danger to people.
Two-tone LED (off - red - green) indicates enabling of the VRD. In
the welding process:
• MIG MAG (Synergic and Manual) / JOB: the VRD device is not
managed and therefore the LED always will be off.
•
MMA: the operator can decide whether or not to activate the
VRD device (to activate the VRD device see the corresponding
paragraph) based on its necessities and therefore the LED will
be lit and will indicate the activation of the device.
•
TIG Lift: the VRD device is always inserted, independently from
the state of the JUMPER and therefore the LED always will be lit.
■WELDING MODE SELECTION LED
When one or a combination of these LED is lit, it means that the
corresponding manner of welding has been selected.
Switching on the welding
machine and initial screen
At the switching on of the welder (press the switch, located on the
back panel, at the position I), the control performs a short operation
of MACHINE CHECK (all of the LED light themselves simultane-
ously so as to verify their actual operation), and the panel display
the INITIAL SCREEN (see the demonstrative figure), after which
the operator can begin to work.
Viewing the software version installed
1) When the welding machine is working hold down the WELD-
ING PROCESS SELECTION key (T2) and WELDING MODE
SELECTION key (T3) together for about 2 consecutive sec-
onds.

2) On both displays appears a running string that indicates the
VERSION OF THE SOFTWARE installed on the welder.
The rotation of one of the two ENCODER Knobs - A (E1) or
V (E2) by the operator during the display of the string version
software provokes the block (for 1second), on both the dis-
plays, of the movement of the string itself.
E2E1
3) Ending viewing of the software version on the control panel
can come about in 2 different ways:
• Automatically: by waiting for the display time to elapse.
• Manually: by pushing any key.
Loading of the wire
In the MIG-MAG-PULSE-DOUBLE PULSE welding processes,
with the welder in operation, it is possible to load the wire inside
the torch, following this simple procedure:
• Keep the torch button held down.
• After a time of about 2 seconds, the wire begins to load itself at
a constant speed.
•
This operation is also indicated by a message made up of a nu-
merical value for the wire speed, followed by “LoAd” (see figure).
• Rotate the ENCODER - A (E1) knob to change the wire load-
ing speed.
• To finish the loading of the wire release the torch button.

Special functions “Fx”
To access the SPECIAL FUNCTIONS “Fx” menu, hold the SPE-
CIAL FUNCTIONS “Fx” key (T3) down for at least 3 consecutive
seconds. The Fx LED switches on.
T3
T > 3 s
The special functions allow the operator to regulate further param-
eters, operations and do partial resetting, and are operative, in a
different way, within each welding process.
Table 1 shows the special functions available. Details of the mean-
ing of the columns are as follows:
• FUNCTION column: name of the special function.
•
DISPLAY column: symbol for the special function (message
shown in the PARAMETERS DISPLAY -A screen).
•
FACTORY column: Factory setting for the special function (mes-
sage shown in the PARAMETERS DISPLAY - V screen).
• RANGE column: regulation field for the special function.
•
The last two groups of columns, WELDING PROCESS and
MIG-MAG WELDING MODE indicate the welding process and
mode in which the special function can be selected. Example:
the SPOT WELDTIME function can be selected only when one
is welding in synergistic MIG-MAG-PULSE or manual SPOT
2T mode.
1) Rotate the ENCODER - A knob (E1) to select the SPECIAL
FUNCTION required. Rotate the ENCODER - V knob (E2) to
edit the VALUE for the special function selected.
WARNING: Changes to values are immediately activated (no fur-
ther confirmation is required and they will be displayed immedi-
ately) or, at least they will become active the next time welding is
done. The operator can edit the functions (not the wire speed and
other parameters) when welding is underway and continue weld-
ing without having to exit the SPECIAL FUNCTIONS “Fx” menu.
E2E1
2) PROGRAM DEFAULT (dEF)
WARNING: If carried out, this operation resets the program
in use to the factory default settings.
To carry out the reset of the settings / parameters, proceed in
the following manner:
• Rotate the ENCODER -A (E1) knob until both the displays
read dEF no (see figure).
E1
• Rotate the ENCODER - V knob (E2) until the PARAME-
TERS DISPLAY - V screen (D2) reads YES.
D2
E2
• Hold the SAVE “MEM” key (T2) down for at least 2consec-
utive seconds.

T ≥ 2 s
• The program in use has now been completed successfully.
To confirmation the above, the control panel of the welder
performs a short operation of MACHINE CHECK (all of the
LED stay lit simultaneously so as to verify their actual op-
eration), the generator itself starts, having memorised the
new settings and is again ready to weld.
