5.3.1Connectingtothegasbottle(ifused)

- The gas bottle that can be positioned on the trolley supporting surface: max 30kg.

- Screw the pressure reducer(*) onto the gas bottle, inserting the appropriate adapter

supplied as an accessory when Argon or an Argon/CO

mixture is used.

- Connect the gas input hose to the reducer and tighten the clamp.

- Loosen the adjustment ring nut on the pressure reducing valve before opening the

gas bottle valve.

(*) Accessory to be purchased separately if not supplied with the product.

5.3.2Connectingtheweldingcurrentreturncable

Must be connected to the workpiece or to the metal bench on which it is positioned,

keeping it as close as possible to the joint being done.

5.3.3Torch

Prepare the torch when loading the wire for the rst time, by dismantling the nozzle

and the contact tip, to ease its exit.

5.3.4Polaritychange

Fig.B

- Open the reel area door.

- MIG/MAG welding (gas):

- Connect the torch cable to the red clamp (+).

- Connect the clamp return cable to the black clamp (-).

- FLUX welding (no gas):

- Connect the torch cable to the black clamp (-).

- Connect the clamp return cable to the red clamp (+).

- Close the reel area door.

5.3.5Recommendations:

- Screw the welding cable connectors right down into the quick couplings (if present),

so as to ensure perfect electrical contact; otherwise, the connectors will overheat,

wear rapidly and become inefcient.

- Use welding cables that are as short as possible.

- Do not use metal structures that are not part of the workpiece to substitute the welding

current return cable; this could endanger safety and produce an unsatisfactory weld.

MAKESURETHEWELDINGMACHINEISSWITCHEDOFFANDDISCONNECTED

FROMTHEMAINPOWERSUPPLYOUTLET.

MAKE SURE THAT THE WIRE FEEDER ROLLERS, THE WIRE GUIDE HOSE AND

THE CONTACT TIP OF THE TORCH MATCH THE DIAMETER AND TYPE OF WIRE

TO BE USED AND MAKE SURE THAT THESE ARE FITTED CORRECTLY. WHEN

INSERTING AND THREADING THE WIRE DO NOT WEAR PROTECTIVE GLOVES.

- Open the reel compartment door.

- Position the wire reel on the spindle, holding the end of the wire upwards; make sure

the tab for pulling the spindle is correctly seated in its hole (1a).

- Release the pressure counter-roller(s) and move them away from the lower roller(s)

(2a);

- Make sure that the towing roller(s) is suited to the wire used (2b).

- Free the end of the wire and remove the distorted end with a clean cut and no burr;

turn the reel anti-clockwise and thread the end of the wire into the wire-guide infeed,

pushing it 50-100mm into the wire guide of the torch tting (2c).

- Re-position the counter-roller(s), adjusting the pressure to an intermediate value,

and make sure that the wire is correctly positioned in the groove of the lower roller(s)

(3)

- Remove the nozzle and contact tip (4a).

- Insert the welding machine plug in the power supply outlet, switch on the welding

machine, press the torch button and wait for the end of the wire to pass through the

whole of the wire guide hose and protrude by 10-15 cm from the front part of the

torch, release the button.

WARNING! During these operations the wire is live and subject to

mechanical stress; therefore if adequate precautions are not taken the wire

couldcausehazardouselectricshock,injuryandstrikingofelectricarcs:

- Do not direct the mouthpiece of the torch towards parts of the body.

- Keep the torch away from the gas bottle.

- Re-t the contact tip and the nozzle onto the torch (4b).

- Check that wire feed is regular; set the roller and spindle braking pressure to the

minimum possible values making sure that the wire does not slide in the groove and

when feed is halted the loops of wire are not loosened by excessive reel inertia.

- Cut the end of the wire so that 10-15 mm protrude from the nozzle.

- Close the reel compartment door.

6.WELDING:PROCESSDESCRIPTION

6.1SHORTARC

The wire melts and the weld bead detaches because the wire tip in the weld pool short-

circuits (up to 200 times per second). The free length of the wire (stick-out) is normally

between 5 and 12 mm.

6.2PROTECTIVEGAS

The protective gas ow rate must be 8-14 l/min.

7.OPERATIONMODE

7.1OperationinSYNERGICmode

When the parameters such as material, wire diameter , gas type have been

dened by the user, the welding machine sets itself automatically in the best operation

conditions established by the different synergy curves that are saved. The user only

has to select the material thickness to begin welding (OneTouch Technology).

7.1.1LCDdisplayinSYNERGICmode(Fig.F)

N.B.: All the values that are shown and that can be selected depend on the type of

welding selected previously.

1- Synergy operation mode

;

2- Material to be welded. Types available: Fe (steel), SS (stainless steel), Al

(aluminium), CuSi/CuAl (galvanized plate - brazing), Flux (cored wire - NO GAS

welding);

3- Diameter of the wire to be used. Values available: 0.6 - 0.8 - 0.9 - 1 - 1.2 mm;

4- Recommended protective gas. Types available: Ar/CO

, CO

, Ar, Ar/O

;

5- Thickness of the material to be welded. Values available from 0 to 5 mm;

6- Graphic indicator of the material thickness

7- Graphic indicator of the welding seam shape;

8- Welding values;

wire feed speed;

welding voltage;

welding current;

7.1.2Settingtheparameters

To access the parameter adjustment menu press the knob (Fig. C-2) for at least 1

second then release it:

a) material selection (Fig. F-2 material ashing)

- rotate the knob (Fig. C-2) to select the required material and conrm by pressing

and releasing the same knob;

b) wire diameter selection (Fig. F-3 wire diameter ashing)

- rotate the knob (Fig. C-2) to select the required material and conrm by pressing

and releasing the same knob;

c) gas selection (Fig. F-4 gas type ashing)

- rotate the knob (Fig. C-2) or directly select the proposed gas and conrm by

pressing and releasing the knob; this allows exiting from the parameter settings

menu and the display on the monitor of the pre-set values.

After having dened with the knob (Fig. C-1) the material thickness (Fig. F-5) the user

can start welding.

7.1.3Adjustingtheweldingseamshape

The shape of the welding seam can be adjusted using the knob (Fig. C-2) which

adjusts the arc length, therefore establishing the higher or lower temperature for

welding.

The adjustment scale ranges from -9 ÷ 0 ÷ +9; in most cases the optimal basic setting

is given (the value is shown on the LCD display to the left of the graphic signal showing

the welding seam and disappears after a set time) when the knob is in the intermediate

position (0

Using the knob (Fig. C-2) the graphic indication on the display of the welding seam

changes, showing a more convex, atter or more concave result.

Convexshape.

It means that there is a low thermal supply therefore welding is

“cold”, with little penetration; rotate the knob clockwise for greater thermal supply to

weld with higher fusion.

Concaveshape.

It means there is a high thermal supply therefore welding is too

“hot”, with excessive penetration; rotate the knob counter-clockwise for lower fusion.

7.2OperationinMANUALmode

The user can personalise all the welding parameters.

7.2.1LCDdisplayinSYNERGICmode(Fig.F)

1- Manual operation mode

;

2- Welding values;

wire feed speed;

welding voltage;

welding current;

7.2.2Settingtheparameters

In manual mode, the wire feeding speed and the welding voltage are adjusted

separately. The knob (Fig. C-1) adjusts the wire speed, the knob (Fig. C-2) adjusts

the welding voltage (which determines the welding power and inuences the seam

shape). The welding current is shown on the display only during welding.

8.CONTROLLINGTHETORCHPUSH-BUTTON

8.1Torchpush-buttoncontrolmode

3 different torch push-button control modes can be set, which remain valid with both

synergic and manual operation:

Spotweldingmode(Fig.H-5)

Use for MIG/MAG spot welding with control of welding duration (when at OFF

excluded; 0.1÷5 seconds).

2Tmode(Fig.H6)

Welding begins when the torch push-button is pressed and ends when the push-

button is released.

4Tmode(Fig.H6)

Welding begins when the torch push-button is pressed and released, and ends only

when the torch push-button is pressed and released a second time. This mode is

useful for long welding operations.

8.2Settingthetorchpush-buttoncontrolmode

To access the parameter adjustment menu press the knob (Fig. C-2) for at least 3

second then release it:

a) spot welding time adjustment (Fig. H-2 ashing)

- rotate the knob (Fig. C-2) to select the required time or select “OFF” to disable the

function; conrm by pressing and releasing the same knob.

If the spot welding time is set at a value of between 0.1-5 sec., the “2T/4T” modes
