supply point and adjust the pressure using the reducer knob until the manometer
shows a value close to 8 bar (116 psi).
This operation must only be carried out if the arm moves horizontally even after having
For this operation proceed as follows:
- Release the arm by rotating the release lever (Fig. R);
- Loosen the dowel (Fig. S-1) and tighten the ring nut (Fig. S-2) by one-eighth of a
- Lock the ring nut, tightening the locking dowel (Fig. S-1);
- Lock the arm, following the operation shown in Fig. T.
This operation may need to be carried out several times, either tightening or loosening
the ring nut , until the arm is locked horizontally and the locking lever, using
rotational power that is suitable for manual release, simultaneously closes at the stop
created by the reference plug (Fig. T-1).
NOTE: when the operation ends, the lever must be against the end stop plug (Fig.
T-1). This position guarantees that the "C" arm is locked mechanically and therefore
safe.
The following checks must be carried out before doing any spot welding, and with the
main switch at "I" (ON).
Clamp electrode alignment:
- Place a shim having the same thickness as the panels to be spot welded between
the electrodes; make sure the electrodes, which are now "squeezing" the panels
(see paragraph 6.2.2), are aligned.
The parameters that determine the diameter (section) and mechanical seal of the
spot are:
- Power applied by the electrodes.
- Spot welding current.
- Spot welding time.

spot welded.
Press the "START" key (Fig. U-1) and set the arm among those available (Fig. U-2)
turning the central knob (Fig. C-5).
Adjustment of force takes place in automatic or manual mode (using the pressure
regulator on the air unit).
Setting the automatic mode (default setting) or manual mode allows you to choose

Newton" using the "MANUAL" mode (Fig. U-5).
In "SMART AUTOSET" and "EASY" mode, during the spot welding cycle, the force of
the electrodes is automatically adjusted.
Manual adjustment:
Choosing "no AUTO daN" you can set the force value manually on the pressure
regulator (Fig. B-10).
During the spot welding cycle, the force of the electrodes will be manually regulated
according to the procedure described above.
Approach function
It allows approach of the electrodes with the force set without supplying current.
You can approach the electrodes in any spot welding program with the following
procedure (double click):
Press and release the clamp button and then immediately press the button. The clamp
approaches and keeps closed the electrodes up to subsequent release of the button.
approach by double clicking. It is therefore advisable to select the approach
function .
The spot welding parameters are all set automatically by the machine: "SMART
AUTOSET" mode. You need that both the plugs on the clamps C are connected to
the machine (Fig. F).
The spot welding parameters are set by the machine selecting the thickness and the
material (*) of the sheet metal to weld.
The spot weld is deemed to have been performed correctly when a piece undergoes
two sheets.
(*) NOTE: the standard materials available are:
- "Fe": sheet metal in iron with low carbon content;
- "FeZn": galvanised sheet metal in iron with low carbon content;
- "Br": sheet metal in boron steel.
