1 - Double function key
a) BASIC FUNCTION: sequential display of the spot welding parameters:
power/current that can be emitted, squeeze power/time, pre-spot time, cold time,
slope time, spot welding time, number of impulses (only in pulsed mode), post-spot
time.
b) SPECIAL FUNCTION: modification of the displayed spot welding parameters
and program personalisation.
To access this function follow the procedure described in paragraph 6.2.5.
2 - Function and tool selection key
Pneumatic clamp operation with continuous spot welding current:
The spot welding cycle begins with a squeeze time, continues with a pre-spot time and
a pause (these parameters can be excluded), a ramp time (can be excluded), a spot
welding time, and ends with a post-spot time (can be excluded).
Pneumatic clamp operation with "pulsed" spot welding current:
The spot welding cycle begins with a squeeze time, continues with a pre-spot time
(this parameter can be excluded), a pause, a slope time (can be excluded), a spot
welding time, a series of impulses (see "Number of impulses" in this section), and
ends with a maintenance time that cannot be set.
This function improves spot welding capacity on coated panels (galvanized) or on
panels with special protective films.
Studder function (only with studder gun).
This function can only be selected by connecting the studder gun correctly to the outlet
in the standard clamp (see paragraph 5.9 connecting the studder).
The work that can be done with this function is schematized on the control panel (fig.
C) with the following meaning:
Spot welding with suitable electrodes of: plugs, rivets, washers, special
washers, wavy wire.
Spot welding with relative electrode of screws Ø 4 mm.
Spot welding with suitable electrode of: screws Ø 5÷6 mm and rivets Ø
5 mm.
Spot welding with suitable electrode on only one side of the panel.
Panel tempering with carbon electrode.
Panel upsetting with relative electrode.
Intermittent spot welding with relative electrode for patching on sheet.
3 - "Cursor" keys:
Move the cursor inside the Display.
4 - Double function encoder:
a) BASIC FUNCTION: variation of the selected values.
Rotate the knob: to select a value from among those available for a given function.
b) SPECIAL FUNCTION: "ENTER" – confirms the selected value
Press the knob: to confirm the selected value.
5 - Double function key:
a) BASIC FUNCTION: "MODE" - sequential key.
When pressed in sequence, this key activates these modes (8-pin clamp plug
disconnected from the outlet shown in fig. B-4):
SEMI-AUTOMATIC MODES:
- EASY (only one panel with studder or two equal panels);
- PRO (two equal or different panels);
- MULTI (three equal or different panels);
MANUAL MODE:
- CUST (Custom = List of personalised spot welding programs).
AUTOMATIC MODE (8-pin plug of the clamp connected to the outlet shown in fig.
B-4):
- AUTOMATIC (all the parameters are set automatically by the machine)
MAINTENANCE electrode squeeze without current, automatic or manual force
adjustment, arm length and type A flat or type E point electrode setting, as per ISO
5821).
NOTE: One or more functions can be available or not according to the tool
used.
b) Special FUNCTION: " MENU ".
To access the "Menu" function, keep the "MODE" key pressed for at least 3
seconds.
To exit from "Menu", keep the key pressed again for 3 s.
Use the key to access these secondary functions:
- VERSION of the current Software.
- LANGUAGE (user language setting).
- DATE (current date setting).
- TIME (current time setting).
c) Advanced FUNCTION: "MENU" (with USB flash drive inserted or PC
connected to the machine).
To access this function, keep the "MODE" key pressed for at least 3 seconds.
To exit from "Menu", press the key again for 3 s.
Use the key to access these advanced functions, but ONLY if the USB drive or the
PC is connected to the machine:
- SAVE RECORD (saves a spot welding operation).
- EXPORT PROGRAMS (exports the CUSTOM programs to an external memory).
- IMPORT PROGRAMS (imports the CUSTOM programs from the external
memory).
- UPDATE FIRMWARE
Note: for a more in-depth description refer to the quick guide for the "MENU"
functions.
6 - "ESC" key:
Use to exit from the active selection and return to the initial display without saving any
modifications that have been made.
ATTENTION! Pressing "ESC" and "MODE" simultaneously when the
machine is started recalls the factory settings; the personalised programs will
be cancelled!
7 - Display:
Shows all the information needed by the user to set spot welding according to the
functions used.
8 - "START" key:
To start the machine for normal operation or after an alarm situation.
NOTE: The display shows the operator, when necessary, that the "START" pushbutton
must be pressed in order to use the machine.
9 - General alarm LED, spot welding LED, recording LED:
Yellow general alarm LED
overvoltage, undervoltage, no phase, no air, no water, accidental spot welding short
circuit alarms cut in.
Red "spot welding" LED
Red "REC" (recording) LED
parameters of the spot to be carried out.
NOTE: The information is ONLY recorded in the USB flash drive.
4.2.2 Pressure adjustment group and manometer (fig. B-9)
Use to adjust the pressure applied at the pneumatic clamp electrodes using the
adjustment knob (only for pneumatic clamps in the "Manual" mode).
4.3 SAFETY AND INTERLOCK FUNCTIONS
4.3.1 Safeguards and alarms (TAB. 1)
a) Thermostatic safeguard:
It cuts in if the spot welder becomes too hot because there is no cooling liquid or if
the liquid flow rate is not sufficient, or if a work cycle exceeds the permitted limit.
on the control panel lights up when this safeguard cuts in.
The yellow LED
The alarm is shown on the display by:
AL 1 = thermal safety alarm.
AL 2 = clamp thermal alarm.
AL 8 = studder thermal alarm.
EFFECT: movement stopped, electrodes opened (cylinder to discharge); current
stopped (welding impeded).
RESET: manual ("START" pushbutton pressed after the limits have returned within
those permitted – the yellow LED
b) Main switch:
- Position "O" = open and lockable (see chapter 1).
WARNING! The internal terminals (L1+L2+L3) for connecting the power cable
are live when the main switch is at "O".
- Position "I" = off: spot welder powered but not operating (STAND BY –the
"START" pushbutton needs to be pressed).
- Emergency function
While the spot welder is operating, opening (pos. " I "=>pos "O" ) determines a
stop in safety conditions:
- current inhibited;
- electrode opening (cylinder to discharge);
- automatic restarting inhibited.
WARNING! PERIODICALLY MAKE SURE THE SAFETY STOP IS
OPERATING CORRECTLY
c) Compressed air safety
Activates if the compressed air pressure (p < 3bar) drops or is absent;
The intervention is signalled on the display by AL 6 = no air alarm.
EFFECT: movement stopped, electrodes opened (cylinder to discharge); current
stopped (welding impeded).
RESETTING: manual ("START" pushbutton pressed) after returning within the
permitted pressure limits (manometer indicates >3bar).
d) Output short circuit safety (only pneumatic clamp)
Before starting the welding cycle, the machine checks that the poles (positive and
negative) of the secondary welding circuit have no accidental contact points.
The intervention is signalled on the display as AL 9 = output short circuit alarm
EFFECT: movement stopped, electrodes opened (cylinder to discharge); current
stopped (welding impeded).
RESETTING: manual ("START" pushbutton pressed after having removed the
cause of the short circuit).
e) No phase safeguard
The intervention is signalled on the display by AL 11 = no phase alarm.
EFFECT: movement stopped, electrodes opened (cylinder to discharge); current
stopped (welding impeded).
RESETTING: manual ("START" pushbutton pressed).
f) Undervoltage and overvoltage safeguard
Intervention is signalled on the display by AL 3 = overvoltage alarm and by AL 4 =
undervoltage alarm.
EFFECT: movement stopped, electrodes opened (cylinder to discharge); current
stopped (welding impeded).
RESETTING: manual ("START" pushbutton pressed).
g) "START" pushbutton (Fig. C-8).
It must be pressed to command welding in each of these conditions:
- each time the main switch is closed (pos "O"=>pos " I ");
- after the safety/protective devices cut in;
- after the power supplies (electricity and compressed air) that were previously
interrupted because of upstream disconnection or failure have returned.
WARNING! PERIODICALLY MAKE SURE THE SAFETY STOP IS
OPERATING CORRECTLY
5. INSTALLATION
WARNING! ALL INSTALLATION OPERATIONS AND ELECTRICAL AND
PNEUMATIC CONNECTIONS MUST ALWAYS BE CARRIED OUT WITH THE SPOT
WELDER SWITCHED OFF AND DISCONNECTED FROM THE POWER SUPPLY.
THE ELECTRIC AND PNEUMATIC CONNECTIONS MUST ONLY BE CARRIED
OUT BY EXPERT OR QUALIFIED TECHNICIANS.
