Instructions for use:

Open the press by releasing and extracting the two closing bolts located at both ends of the top plate.

WARNING: Before opening the press, check that the inflation pressure of the manometer is 0 bar.

Preparing the joint Place the first end of the belt on the lower silicone, well centred on the support tray and making sure the joint is within the welding zone of the hotplate.

Then place two sufficiently large scraps and the same material offered up to weld, at both ends and properly tangential to the belt, and fix them using the same holding bar. It is also possible to use metal callipers of the same thickness as the belt and, when necessary, use scraps of the same belt after the callipers to fill out the welding zone.




NOTE: It is always recommendable to fill out the material, at least to 70% of the pressing surface, to avoid deformation in the plates or thickness differences in the welding. Afterward, insert the second end of the belt, leaving the whole surface to be joined fully in contact with the first end already fixed, and hold it with the other holding bar.

Once the joint placement operation has been completed, we cover the whole welding surface with silicone or adequate silicone paper recommended by the belt manufacturer.




Thus, on completing the welding, we guarantee that the joint zone has the same texture and finish as the rest of the belt. Before losing the press, we place the metal plate for flat belts or fibreglass plate for conveyor belts, according the material to be welded, to avoid marks caused by the radical change of temperature and pressure outside the welding zone.

NOTE: Due to the purpose of our pressing devices being to guarantee good welding, they are always supplied with a metal iron to guarantee thermal contact and homogeneous welding, and as fibreglass is an insulating material, the programmed the temperatures and control times must be increased.

We close the press, centring the upper plate well against the lower one and making sure that the water and electrical connection are at the same end of the press.




Once the upper plate has been put in place, we close the press using the closing controls, softly pressing with just two fingers, and in a balanced way on both sides. NOTE: To obtain homogeneous pressure throughout the surface, it is always recommended not to press the closing controls too much, so the pneumatic cushion will thus work in a more balanced way. We can now proceed to inflate.

Inflation:

WARNING: Always make sure the press is correctly closed before inflating. There is a risk of explosion of the top plate. We connect the mini-compressor to the power to on the standard 220v. socket.




You can activate the power in this socket with the cooling button function when press is STOP mode.

We then connect the inflation tube to the intake point on the press, simply by pushing it together.

We start up the compressor with the switch at position I AUTO.




We control the inflation visually using the press manometer.

Once the required pressure has been reached, we shall stop the compressor with 0 STOP and disconnect the air tube of the press, moving the ring of the coupling piece inward. NOTE: It is always recommended to disconnect the inflation tubes during the welding process to avoid pressure leaks through the actual compressor.

Connection: We may now connect power supply top cable to 230V. To do so, it is recommended to check the voltage on the manufacture plate or in information display I before connecting it to the grid.

Programming: Now of starting up display show the actual temperatures of the press and the last welding time programmed.




You can see the temperatures assigned in each plate, pressing the top or bottom button.

To change these values, we must hold top or down button during 3 seconds and when value is

blinking change the value with + or – buttons, after 3 seconds more, the value will be

memorized. To modify the welding time, hold the time button during 3 seconds and when value is blinking

change the value in minutes with + or – buttons, after 3 seconds more, the value will be

memorized.

The board shall memorise these values, showing the present ones again. NOTE: The minimum and maximum temperatures that may be programmed are 10 to 200 ºC. Once the two temperatures and time values are programmed, we press START button to initialize the process.




NOTE: You must connect the water pump or air blower in the rear socked and when welding time be finished, the control turn on automatically this device until press is cooled at 65ºC

Connecting the water cooling circuit: This connection of the cooling circuit hoses must be performed before the press reaches the welding temperatures; otherwise this may lengthen the welding time. To that end, we shall connect the two hoses from the water pump in each of the top and bottom plates, just as shown in the image.

Afterward, we shall connect the two drainage hoses the other two top and bottom conducts.

NOTE: We shall not submerge or turn on the water pump until the welding time ends.

Connecting the air blower cooling: Introduce the four air hoses inside the steel tubes.




We then connect the water pump, or the air blowing unit to cool the equipment, until reaching the temperature of 65 º C. NOTE: It is recommended to empty the water from the circuit inside the press after each welding, otherwise we may weld wrongly. Once the welding has ended, we deflate the press pressure by inserting a punch in the air coupling.

We can then proceed to open it.
