- each time the safety/protection devices cut in;
- when the power supply is reinstated (electricity) following a shutdown of power
supplies or a malfunction;
Unpack the spot-welder, assemble the separate parts included in the package.
WARNING: None of the spot-welders described in this handbook have lifting devices.
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.
compact, and suitable for supporting the weight (see "technical data") to prevent the
danger of toppling or dangerous movements.
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:
) for single-phase machines;
- Type A (
- 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).
The power supply cable is supplied with a Schuko (2 poles + earth) plug already
assembled.
Connect a standard plug (3P + E: only 2 poles are used: INTERPHASE connection!)
to the power supply cable of adequate capacity.
Prepare a mains socket protected with fuses or an automatic circuit breaker switch;
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.
Before commencing any spot welding operations, check, with the power cable
disconnected from the mains, that the electrical connection is performed correctly in
accordance with the instructions above.
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 (for "DUO" version
only).
- Connect the 14 PIN connector of the studder gun with trigger to the socket in Fig.
B-3 (for "DUO" version only).
- To the socket in Fig. B-4 connect the studder gun without trigger or the quick
connection cable (see catalogue).
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.
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

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.
To spot weld, just place 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.

b) Bare the sheet metal as near as possible to the point where you intend to work, for
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
Note: if the earth electrode should easily detach during traction, try to increase the
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
indicated previously.
Select the icon of the slotted washer using the potentiometer.
This function is executed by assembling and tightening the electrode holder (POS. 28,
Fig. D) of the gun. Insert the slotted washer (POS. 27, Fig. D) in the electrode holder
and spot weld as previously described.
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.
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.
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.

This function is carried out by assembling and tightening the spindle (POS. 3, Fig. D)
onto the body of the electrode (POS. 1, Fig. D). Hook the washer (POS. 13, Fig. D),
