-Description of the equipment:

➢Heating press for fusion welding of conveyor belts, comprised of two aluminium plates

with cartridge electric elements, controlled by an external temperature board.

➢Pressure by pneumatic cushions to guarantee uniform pressing.

➢Intermediate support tray to prepare and hold the joint while hot.

➢Interior cooling circuit, by water, and by air in some models, too.

-Technical characteristics:

Model FRA-100

- Control box unit options CB02 - CB01/3

- Dimensions (LxWxH) 1630x800x1570mm

- Weight 340kg

- Maximum temperature 200ºC

- Minimum length belt (mm.) 1250

- Heating area (mm.) 1050x160

- Maximum pressure 2.5 bar

- Heating time 20ºC-170ºC 6 min

- Cooling time with water 25ºC (170ºC-50ºC) 1.7min

- Power W. 4080

-Workshop installation:

These presses may be used both for in-situ assembly, as well as in fabrication workshops, for

which it is recommended to adapt the press to a metallic supporting structure, with pneumatic

or counterweighted activation, to open the top plate and adapt the water cooling circuits

correctly.

Place the control board on the rack at eye level, safely to avoid it breaking or falling.

Level the support with the regulation screws located inside the three legs.

NOTE: Once the frame is leveled, you most to introduce the trolley to level the wheels.

The distance between bottom plate and steel plate of trolley is 1 or 2 mm.

We can modify this distance across the wheel’s screws.

NOTE: In the case of several presses being connected to the same drainage line,

installation of a one-way valve at each press is recommended, thus avoiding water

entering the other presses during the purge process.

Connect control board CB-01

(For further information, consult the User Manual for CB-01)

-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.

Up the top plate using the manual valve in UP position.

-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 closing the press, we place the metal or fibreglass plate, according to the material to be

welded, to avoid marks caused by the radical change of temperature and pressure outside the

welding zone.

We introduce the trolley inside the press and down the top plate

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 inflate the press turning the white wheel of pressure control until bar required.

We control the inflation visually using the manometer.

Programming:

At the moment of starting up the board, the actual temperatures of both plates are displayed,

and the welding time of the last programming.

To see the temperatures assigned, it shall suffice to press the relevant button for each plate.

To change these values, we must hold down the button for 3 seconds and change the value

using the central keys.

The board shall memorise these values, showing the present ones again.

NOTE:

The minimum and maximum temperatures that may be programmed are 30 to 200 ºC.

We shall perform the same operation to program the welding time, ALWAYS IN MINUTES. The

values shown are complete minutes without decimals.
