-Description:
Welding equipment for heat-weldable round belts with a heating plate that is automatically
interposed between the two ends of the belt at a certain temperature and time, and
automatically withdraws, closing the joint and cooling.
-Technical characteristics:
Dimensions 470x400x330mm.(LxWxH)
Weight 14 Kg
Minimum development 260mm.
Max. Diameter 15mm.
Voltage 1x 230 v 50/60Hz
Power 270 W
Work pressure 5/6 Kg/cm²
Max. temperature 520º C
-Installation and connection:
Connect the power cable that comes out of the machine to 230V. Then we must provide
compressed air, through the air tube at a minimum pressure of 5Kg/cm2.
Place the machine on a table or workbench at a comfortable height for the operator, making sure
that the device is stable and secure.
Leave the electric pedal on the ground and adjust it to a comfortable position without getting in
the way or causing a trip.
-Using instructions:
WARNING:
THIS DEVICE INVOLVES THE DANGER OF FINGER ENTRY BETWEEN THE CORD HOLDING
CLIPS, THEREFORE THE OPERATOR MUST BE EXTREMELY CAUTIOUS IN THAT AREA.
Once the machine is connected to the network and provided with compressed air, we will start
the device through the protection switch located on the back.

Note: We must wait 2/3 minutes once the temperature is reached for the heat of the
solder plate to stabilize.
Temperature programming
To set the desired temperature, press once on the (F) key of the controller where the
programmed temperature will be shown, and then we will modify the value through the arrows
(G and H).
After modifying the value, we will press the (F) key again to accept and exit programming.
NOTE:
The maximum programmable temperature is 520ºC, but it must be taken into account
that the value taken by the temperature controller is from inside the resistance.

Time scheduling
To enter the welding and cooling times, we must touch on the screen on the numerical value to
the right of each time bar, and another screen will open with a keyboard to enter the value
(always in seconds) and accept it by pressing ENTER.
The time values will remain memorized until they are modified again.
Pressure adjustment
Setting the cooling pressure is important for different types of material or diameters.
To do this, this device has been equipped with a closing pressure regulator and a closing stroke
mechanical stop.
The excess or lack of pressure during the closing of the weld is as important as the temperature
or time values.
To regulate the pressure, just turn the regulator knob (R) by pulling it out slightly to unlock it
and the pressure will be displayed on the pressure gauge (P) on the left.
NOTE: The pressure adjustment should only be made during the cooling cycle, otherwise
the pressure gauge will always be 0.

To regulate the closing stroke mechanically, we will adjust the bolt located at the bottom of the
sliding base with an 8mm wrench.
Strap introduction
WARNING:
For this operation, it is important that the operator leaves enough space between the
fingers and the end of the belt to avoid entrapment of the jaws.
To place the ends to be welded, we will activate the distance gauge by pressing and holding the
pedal until both ends are well positioned against the central gauge.
Releasing the pedal will lower the two jaws to secure the ends of the belt and then the gauge will
automatically be removed to start the cycle.
NOTE: The cycle can be interrupted at any time by pressing the EMERGENCY button.
Therefore, if we see that the introduction of the strap has not been correct, we will stop the
process and repeat it again.

WARNING:
ATTENTION: During the welding cycle, the heating plate is outside the protective
compartment, which may cause serious burns.
For this reason, it is recommended to exercise extreme caution during this operation,
keeping the extremities away from this area.
For a good weld, it is essential that the cuts at the ends of the belt are perfectly straight, for this it
is recommended to use special scissors for belts equipped with guides.
INFORMATION:
This device can also be used for V-belts or with other geometry, if said geometry allows us to
insert them correctly aligned.
