Opening the spot welding machine when it is operating (pos. "I" => pos. "O") will
instantly stop the machine in safe shutdown mode with:
- current inhibited;
- automatic restart inhibited.

This push-button must be pressed to control welding in each of the following
conditions:
- every time the main switch has tripped (pos. "O" => pos. "I");
- each time the safety/protection devices cut in;
- when the power supply is reinstated (electricity and compressed air) following a
shutdown of power supplies or a malfunction;
5. INSTALLATION

5.1 UNPACKING

Unpack the spot welder, assemble the separate parts (to be found in the packaging)
as indicated in this chapter (Fig. D).
The spot welder must be lifted using a double cable and hooks that are suitably sized
for the machine weight, and using the relative M12 rings.
It is forbidden to sling the spot welder using means other than those indicated.
Make sure the installation area is suitably large and without obstacles to guarantee
that the control panel, the main switch and the working area can be accessed in
complete safety.
sure that conductive dust, corrosive vapours, humidity, etc. cannot be sucked in.
that is suitable for supporting the weight of the machine (see "technical data") to avoid
the danger of toppling or dangerous movements.
Before carrying out any electric connection, make sure the machine plate data
corresponds with the voltage and frequency of the mains available in the installation
place.
neutral conductor connected to earth.
To guarantee protection against indirect contact use these types of residual current
device;
- A type ( ) for single-phase machines;
- B type ( ) for three-phase machines.
- The IEC/EN 61000-3-12 Standard is not applicable to the spot welder.
If the welding machine is connected to a public electricity grid, the installer or user
must make sure that the machine can be connected (if necessary, consult the
company that manages the electricity grid).
corresponding earth terminal must be connected to the (yellow-green) earth conductor
of the power supply.
The capacity and intervention characteristics of the fuses and circuit-breaker switch
are given in the "OTHER TECHNICAL DATA" paragraph.

5.5 PNEUMATIC CONNECTION

- Prepare a compressed air line with a working pressure of 8 bar.
to make the reducer suitable for the connections where the spot welder is to be
installed.
5.6 PREPARATION OF THE COOLING UNIT (GRA)
the machine switched off and disconnected from the mains supply.
Never use polypropylene based antifreeze liquids.
Only use the coolant recommended by the manufacturer of the cooling unit.
- Open the discharge valve (FIG. B-13).
- Fill the tank with coolant using the nozzle (Fig. B-11): capacity of the tank = 8 l; pay
- Close the tank cap.
- Close the discharge valve.

- Insert the 8 pin polarised plug in Figure F-2 to use the automatic spot welding
mode.
- Insert the cooling tubes(*), respecting the colours (blue tube on blue socket, red
tube on red socket). Check rapid coupling of the tubes is correctly carried out (Fig.
F-3).
correctly resulting in thermal stress which damages the electric parts.
- Disconnect the machine from the mains.
- Turn the block as seen in Fig. G1.
- Now assemble the clamp support (Fig. G2) if used.
- Angle the arm as necessary and slide it into its seat (Fig. G3).
- Align the arm with the piston electrode and tighten the block in place (Fig. G4-A).
- Connect the cooling tubes to the relative quick couplings (Fig. G4-B).
- Now assemble the clamp support sleeve from the correct side (Fig. G5) if used.
properly which will cause thermal stress and damage to the electrical parts.
A series of checks and adjustments must be carried out before starting to spot weld,
with the main switch in the "O" position and the lock closed.
- Make sure the electric connection has been carried out correctly in compliance with
the instructions given previously.
- Check compressed air connection: connect the supply hose to the pneumatic
