5.1PRELIMINARYOPERATIONS

Unpack the spot-welder, assemble the separate parts included in the package.

5.2LIFTINGTHESPOT-WELDER

WARNING: None of the spot-welders described in this handbook have lifting devices.

5.3 POSITION

Reserve a space in the installation area that is large enough and without obstacles

for guaranteeing access to the control panel, the main switch and the work area in

complete safety.

Make sure there are no obstacles near the areas where the cooling air enters and exits,

ensuring that conductive power, corrosive vapour, humidity, etc. cannot be sucked in.

Place the spot welding machine on a surface of homogeneous material that is at and

compact, and suitable for supporting the weight (see “technical data”) to prevent the

danger of toppling or dangerous movements.

5.4CONNECTIONTOTHEPOWERNETWORK

5.4.1Warnings

Before making any electrical connection, make sure the spot welding machine plate

data correspond with the mains voltage and frequency available in the installation

area.

The spot welding machine must only be connected to a power supply system with

neutral conductor connected to earth.

To guarantee protection against indirect contact, use residual-current devices of the

following type:

- Type A (

) for single-phase machines;

- Type B (

) for three-phase machines.

- The spot welding machine does not meet the requirements of the IEC/EN 61000-

3-12 directive.

If it is connected to a public power grid, the installer or user must make sure that

the welding machine can be connected (if necessary consult the utility company).

5.4.2Plugandmainssocket

- Version230V:

The power supply cable is supplied with a Schuko (2 poles + earth) plug already

assembled.

- Version400V:

Connect a standard plug (3P + E: only 2 poles are used: INTERPHASE connection!)

to the power supply cable of adequate capacity.

- Mains socket

Prepare a mains socket protected with fuses or an automatic circuit breaker switch;

the specic earth lug must be connected to the earth conductor (yellow-green) of the

power supply line.

The capacity and characteristics of fuse and circuit breaker switch intervention are

outlined in the "TECHNICAL DATA" paragraph.

If multiple spot welding machines are used, distribute the power supply cyclically

between the three phases to create a more balanced load; for example:

spot welding machine 1: power supply L1-L2;

spot welding machine 2: power supply L2-L3;

spot welding machine 3: power supply L3-L1.

6.WELDING(Spotwelding)

6.1PRELIMINARYOPERATIONS

Before commencing any spot welding operations, check the main switch is set to the

"O" position, and the electrical connection is performed correctly in accordance with

the instructions above.

6.1.1 CONNECTION OF TOOLS (Fig. B)

For correct functioning of the machine, connect the tools to the relevant sockets as

described below:

- Connect the studder gun with trigger to the socket in Fig. B-2.

- Connect the 14 PIN connector of the studder gun with trigger to the socket in Fig.

B-3.

- To the socket in Fig. B-4 connect the studder gun without trigger or the quick

connection cable (see catalogue).

WARNING!

- Once spot welding has begun, using the button or contact with the piece, the

machineenergisesboththetoolsconnectedtoit:

- AVOIDRESTINGTHETOOLNOTINUSEONTHEPIECETOWORK!

- ALWAYS BRING THE TOOL NOT IN USE ON A STABLE AND NON-

CONDUCTIVESURFACE!

6.2 PARAMETER ADJUSTMENT (in spot welding)

The parameters that determine the diameter (section) and mechanical seal of the

spot are:

- Force exercised by the electrode.

- Spot welding current.

- Spot welding time.

If there is no specic experience, it is a good idea to carry out some spot welding tests

using sheets of the same quality and thickness as those to be worked on.

The current and spot welding time parameters are adjusted automatically by selecting

the thickness of the sheet to be welded with the (+ / - icons) keys. Adjustments can

be made to the standard spot time (DEFAULT), within set limits, using the key (icon

g. C-2).

6.3 PROCEDURE

6.3.1STUDDERGUNWITHORWITHOUTTRIGGER

- If the gun activates, it is the one WITH THE TRIGGER (see g. C-7) the rst contact

with the sheet metal of the gun WITHOUT TRIGGER activates recognition of the

tool.

After recognition, spot welding begins simply by placing the tool against the piece

to be welded, which is connected to the earth cable: after a few moments, the

machine recognises the contact and starts the spot weld automatically.

- If the active gun is the one WITHOUT the trigger (see g. C-7) simply press the

trigger once on the other gun to select it.

After recognition, spot welding begins simply by resting the tool on the piece to

weld and pressing the trigger.

that stops the spindle from rotating.

- If working on doors or hoods, connect the earth bar to them to prevent

current from passing through the hinges, and near the area to be spot welded

6.3.2 FASTENING THE EARTH CABLE TO THE SHEET METAL

a) Switch on the machine and press the "Start" button (g. C-1). The display shows

the spot welding programme for the earth"

b) Bare the sheet metal as near as possible to the point where you intend to work, for

a surface corresponding to the contact surface of the earth nut (g. D-26).

c) Connect the head of the earth electrode to the eyelet of the earth cable (g. I).

d) Rest the tip of the earth electrode (g. D-25) on the bare sheet metal previously

prepared and close the circuit resting the tip of the studder gun without trigger on

the bare sheet metal.

e) Check the welding seal of the earth electrode by exerting light traction of the

electrode in an orthogonal direction compared to the surface on which it is welded

and then fasten the earth nut against the sheet metal (g. L).

Note: if the earth electrode should easily detach during traction, try to increase the

welding time using the "+" and "-" buttons (g. C-2, C-3).

Washerweldingformassterminalxing

Select the programme in g. C-8a using the “MODE” key.

Mount the relative electrode (POS. 9, Fig. D) in the gun spindle, and insert the washer

(POS. 13, Fig. D).

Place the washer in the selected area. Place the earth terminal in contact in the

same area; press the gun push-button to weld the washer, which should be xed as

indicated previously.

Screw, washer, nail, rivet spot welding

Select the programme in g. C-8b using the “MODE” key.

Fit the most suitable electrode on the gun, insert the element to be spot welded and

place it on the sheet in the necessary spot; press the gun push-button: release the

push-button only after the set time has elapsed.

Contemporaneous spot welding and drawing of special washers

Select the programme in g. C-8a using the “MODE” key

This function can be carried out by assembling and fully tightening the spindle (POS.

4, Fig. D) on the body of the extractor (POS. 1, Fig. D): hook and fully fasten the other

end of the extractor on the gun. Insert the special washer (POS. 14, Fig. D) into the

spindle (POS. 4, Fig. D), and lock it with the relative screw (Fig. D). Spot weld in the

relative area, adjusting the spot welding machine as if spot welding washers, and start

drawing.

At the end, rotate the extractor by 90° to release the washer, which can be spot welded

in a new position.

Sheet heating and upsetting

Select the programme in g. C-8d using the “MODE” key.

In this mode the TIMER is disabled.

Operation duration is therefore manual, being determined by the time for which the

gun electrode is kept pressed on the piece connected to the earth.

Current intensity is adjusted automatically according to the thickness of the selected

sheet.

Assemble the carbon electrode (POS. 12, FIG. D) on the gun chuck and block in place

with the ring nut. Touch the area, that was previously bared, with the carbon tip. Work

from the outside to the inside, using a circular movement to heat the sheet which

undergoes work hardening and returns to its original position.

To prevent the sheet from drawing too much, treat small areas and immediately after

wipe using a damp cloth to cool the treated part.

Sheet upsetting

Select the programme in g. C-8e using the "MODE" key.

In this position, working with the specic electrode, you can atten the sheet metal that

underwent localised deformation.
