5.2 Connexió d'alimentació
- Ensure the power switch on the control panel is in the 'OFF' position.
- Connecteu el cable d'alimentació a la màquina.
- Connecteu el cable d'alimentació a una presa de corrent de 220 V i 50 Hz amb connexió a terra.
5.3 Preparació del material
- Clean the geomembrane surfaces to be welded, ensuring they are free from dust, dirt, moisture, and oil.
- Overlap the two geomembrane sheets according to the required seam width (typically 120mm joint width). Ensure the overlap is consistent and smooth.
- Secure the material to prevent shifting during the welding process.
6. Funcionament
Follow these steps for effective welding with the JIT 900.

6.1 Engegada i configuració inicial
- Turn the main power switch to the 'ON' position. The digital display will illuminate.
- Set the desired welding temperature using the temperature control knob. Refer to the geomembrane manufacturer's recommendations for optimal welding temperature, typically between 0-450°C. Allow the machine to preheat until the set temperature is reached and stable.
- Adjust the welding speed using the speed control knob. Start with a lower speed (e.g., 1-2 m/min) and adjust as needed based on material thickness and desired weld quality.
6.2 Procés de soldadura
- Position the welder at the start of the seam, ensuring the geomembrane sheets are correctly aligned under the welding head and guides.
- Lower the engagement lever to bring the pressure rollers into contact with the geomembrane, applying even pressure.
- The machine will automatically begin to move forward, heating and pressing the geomembrane layers together to form a weld.
- Monitor the welding process to ensure consistent speed and temperature. Adjust settings if the weld quality is not satisfactory.
- At the end of the seam, lift the engagement lever to disengage the rollers and stop the welding process.
6.3 Post-Welding Inspection
- Visually inspect the welded seam for consistency, absence of gaps, and proper fusion.
- Perform peel tests or shear tests on test welds to verify weld strength and integrity, especially when starting a new project or changing material types.
7. Manteniment
Regular maintenance ensures the longevity and reliable performance of your JIT 900 welder.
7.1 Neteja
- After each use, ensure the machine is powered off and cooled down.
- Clean the welding wedge and rollers to remove any accumulated plastic residue or debris. Use a non-abrasive cloth and, if necessary, a suitable solvent recommended by the geomembrane manufacturer.
- Wipe down the exterior of the machine to keep it free from dust and dirt.
7.2 Inspecció
- Regularly inspect the power cord for cuts, fraying, or other damage.
- Check the condition of the welding wedge and rollers for wear or damage. Replace worn components as needed.
- Assegureu-vos que tots els elements de fixació estiguin ben ajustats.
7.3 Emmagatzematge

8. Solució De Problemes
Aquesta secció tracta els problemes habituals que podeu trobar durant el funcionament.
8.1 Machine Does Not Power On
- Comproveu la connexió d'alimentació: Ensure the power cord is securely plugged into both the machine and a live 220V outlet.
- Comproveu el fusible: Inspect the fuse on the control panel (refer to Figure 4). If blown, replace it with a fuse of the correct rating.
- Interruptor principal d’alimentació: Confirm the main power switch is in the 'ON' position.
8.2 Poor Weld Quality (e.g., weak seam, burn-through)
- Configuració de la temperatura: Adjust the welding temperature. Too low a temperature results in a weak weld; too high can cause burn-through. Refer to material specifications.
- Welding Speed: Adjust the welding speed. Slower speeds allow more heat transfer; faster speeds reduce it.
- Material Cleanliness: Ensure the geomembrane surfaces are clean and free of contaminants.
- Roller Pressure: Verify that the pressure rollers are applying adequate and even pressure.
- Components desgastats: Inspect the welding wedge and rollers for wear. Worn components can lead to inconsistent welds.
8.3 Machine Not Moving or Irregular Movement
- Engagement Lever: Ensure the engagement lever is fully lowered to engage the drive mechanism.
- Configuració de velocitat: Check the speed control knob setting.
- Obstruccions: Inspect the path of the machine and the rollers for any obstructions or debris.
