1.2 GENERAL SAFETY WARNINGS
THE FAILURE TO OBSERVE THESE WARNINGS AND/OR ANY MODIFICATION OF OR TAMPERING WITH THE WELDING
MACHINE WILL RELEASE P.E.I.-POINT SRL FROM ANY LIABILITIES IN THE CASE OF ACCIDENTS TO PEOPLE OR DAMAGE
TO THINGS AND/OR TO THE WELDING MACHINE ITSELF.
Before turning the welding machine on it is essential that the user knows how to carry out all the operations described in
this manual.
The manual is an integral of the machine and must be kept until it is disposed of.
RESIDUAL RISKS
By residual risks we mean any hazard that could not be totally eliminated with the design or protection means and any potential
hazard that is not evident.
There must not be excessive quantities of dust, acids, corrosive substances or gases etc., on the
premises except those generated by the welding machine.
We recommend keeping an extinguisher near the workstation.
It must not be excessively humid on the premises.
We recommend using an insulating platform.
All maintenance jobs must be done on the machine only after having disconnected it from the
electricity mains.
Mind your hands when working; always keep them well away from the electrodes and moving parts
when welding.
The strong magnetic field that the welding machine generates during welding can be dangerous for
people wearing pacemakers.
Watches and electronic devices in general, if placed near the welding machine, can be damaged.
Only use the spot welder on a horizontal plane.
If it slants more than 15° with respect to the floor it could tip over.
An incorrect adjustment of welding pressure, an erroneous setting of parameters or malfunctioning
of the pneumatic system can all cause squirts of melted material during welding.
The electrodes become very hot during welding. Do not touch them with your bare hands
immediately after welding.

1.6 DESCRIPTION OF THE PRODUCT AND HOW IT WORKS
P.E.I.-POINT SRL spot welders belong to the family of resistance type welding machines.
By this we mean autogenous welding obtained by pressure, without using weld material, using the thermal effect of electricity flowing
through the components to be welded (Joule effect) for heating.
The components to be welded are gripped between two electrodes with a dual purpose: to let electricity pass through and to exert
enough force for welding.
The intensity of the current, the force on the electrodes and weld time are the most important parameters for welding. Force must be
applied during the electrodes’ squeeze time phases, weld time and holding time.
The welding cycle phases are managed by the welding control unit; the times set are given in mains periods (1/50th of a second if
mains frequency is 50 Hz).
The main switch turns the welding machine on (item 6) which also has the function of an emergency stop switch.
Welding is started the lever switch (trigger) on the studder gun (2).
The welding machine is equipped with safety thermostats to stop operation if it overheats.

3. INSTRUCTIONS FOR THE OPERATOR
3.1 DESCRIPTION OF THE FUNCTIONS
To weld, the operator can either press the green button on the gun or use the lever switch on the studder gun. Squeeze time tests
can be run without welding by pressing the black push button.
When the welding control unit receives consent to start the cycle it performs the welding sequence according to the parameters set
on it.
The sequence can be interrupted at any time by releasing the cycle start push button.
If the start push button is released during weld time, the spot might not be strong enough.
3.2 GUIDE TO STARTING THE WELDING MACHINE FOR THE FIRST TIME
a) power on via the main switch
b) set welding parameters on the control unit (see next paragraph)
3.3 GETTING READY TO WELD
WELDING CYCLE
The welding cycle consists of three basic times:
Squeeze time: it is the interval of time between the start of the cycle and the moment the electrodes, under the
force exerted on them, come into contact with the piece to be welded.
Weld time: this is the time during which the welding current passes through the electrode contact area.
Holding time: this is the time during which the force of the electrodes is maintained after weld time has finished
3.4 INFLUENCE OF THE VARIOUS PARAMETERS ON THE WELDING RESULT
Force on the electrodes
The greater the force is on the electrodes, the weaker contact resistance will be between the electrodes and the sheets and the less
risk there will be of melted material being squirted.
However, the force on the electrodes is limited by the welding machine’s capacity. The greater the force is on the electrodes, the
greater the current value will be to achieve welding.
Weld time
Welding can be achieved with different weld times:
Short weld time: it effects a small area of material being heated but the welding machine’s performance is
( less than 10 periods) superior.
Long weld time: it leaves a heavy electrode mark on the sheets and utilises the machine to the utmost.
( 20-60 periods )
Medium weld time: a good compromise between the two extremes
( 10÷20 periods )

-11 -
Current
Welding current influences the strength of the spot as does weld time but the influence is much stronger.
This means that current is the variable factor and must be adjusted with maximum attention.
To find the optimum welding current you have make several attempts on some sample pieces, starting from a low value (10) and
gradually increasing up to a satisfactory value (max. 100).
Approximate adjustments are given in the following table for the most common uses.
3.5 CHECKING SPOT QUALITY
There are different ways to check the quality of a welding spot.
The best way, for the strength test, is the separation test of the welded parts.
This test entails gripping the welded sample pieces in a clamp and opening them with a scalpel. Strength is good if, after the sheets
have been separated, there is a hole on one sheet and the melted core on the other sheet.
3.6 GUIDE TO STARTING
Prior to welding:
-Turn the welding machine on with the main switch (6) and make sure the green LED (“mains present”) is on.
-Check that the set welding parameters are ideal for the piece you are welding and for electrode aperture (squeeze time).
-Wear individual protection gear (gloves, glasses, aprons, etc.).
Starting:
▪Spotter: Use the gun’s lever switch to spot weld.
Stopping the cycle and emergency stopping:
-The cycle can be stopped at any time, when you take your foot off the pedal.
-To stop in an emergency, turn the main switch off and discharge the pneumatic circuit through the dump valve VS-R (item 7).

PX1600 WELDING CONTROL
DESCRIPTION OF THE SYNOPTIC PANEL
The synoptic panel is divided in two parts. The top shows the graphical symbols of the functions available as well as the LEDs signalling
the function selected. The bottom part has the four arrow keys for programming and a two-digit display that shows the value of the
function selected.

-14 -
DESCRIPTION OF THE FUNCTIONS
PX1600 is a timer that controls the welding cycle . A mains period is the timer’s unit of time, corresponding to 1/50th of a second (50Hz). If,
for instance, a squeeze time of 50 periods is set, time will be equal to 1 second.
Squeeze time (0-99 periods): it is the time needed by the welding machine’s electrodes
to come into contact with the piece to be welded and to exert the welding pressure Melted
material will squirt if this time is too short.
Current risetime (0-20 periods):
Weld time with growing current increase. If this value is not zero, welding current will
gradually reach the value required during risetime. This technique is used when welding
extra thick sheets that are not well matched together, or for welding steel.
Adjustment 1-2:
Welding time and current, together with the force at the electrodes, are the most
important parameters to make a spot weld. If the thickness of the pieces to be welded
differ then (at least) the welding current has to be modified, leaving all the other
parameters as they are. Adjustment 1 or 2 are automatically selected during welding
program execution. If the welder has only one start device, only Adjustment 1 will be
executed.
Weld time (0-99 periods):
time during which the pieces to be welded have welding current passing through them.
Power adjustment (0-99%):
The value of the welding current is determined as a percentage of power.
Number of pulses (1-20):
weld time is repeated without opening the electrodes, according to the value set.
If no. of pulses=1 control makes single cycle with set welding time
If no. of pulses >1 control makes infinite welding time (seam welding)
Cold time (0-99 periods):
pause time between welding pulses.
Holding time (0-99 periods):
No effect on seam welder
Pause time (0-99 periods):
No effect on seam welder
Energy function (0-1):
No effect on seam welder
