2. Safety Instructions

Always observe the following safety precautions to prevent injury or damage to the equipment.

• Ensure the power supply matches the machine's requirements.
• Do not operate the machine in wet conditions or near flammable materials.
• Wear appropriate personal protective equipment (PPE), including heat-resistant gloves and eye protection.
• Important: It is forbidden to press and idle the two pressure wheels at the same time. This can cause damage to the machine.
• Allow the machine to cool down before storage or maintenance.
• Keep children and unauthorized personnel away from the operating area.

4. Setup

1. Unpacking: Carefully remove the welding machine and all accessories from the packaging. Inspect for any signs of damage.
2. Placement: Place the machine on a stable, level surface in a well-ventilated area.
3. Power Connection: Connect the power cord to a suitable power outlet. Ensure the power switch is in the OFF position before connecting.
4. Material Preparation: Prepare the geomembrane material to be welded. Ensure the surfaces are clean and free of debris.

5. Operating Instructions

1. Power On: Turn the power switch to the ON position.
2. Set Temperature: Adjust the temperature control knob to the desired heating temperature (0-450°C) based on the material type and thickness. Allow the machine to reach the set temperature.
3. Set Speed: Adjust the speed control knob to the desired welding speed (0.5-5m/min).
4. Adjust Pressure: The pressure can be adjusted by rotating the corresponding mechanism. Rotating clockwise increases pressure, while counter-clockwise decreases it. Ensure appropriate pressure for the material thickness (0.2mm-1.5mm).
5. Start Welding: Position the machine over the geomembrane sheets, ensuring the overlap width is correct (100mm/100mm/150mm/200mm depending on model/configuration). The machine will automatically begin to climb and weld.
6. Monitor Welding: Observe the welding process to ensure a consistent and strong seam. The intelligent control system will help maintain precise operation.
7. Finish Welding: Once the weld is complete, turn off the power switch and allow the machine to cool down.

This machine is suitable for a wide range of applications:

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

• Cleaning: After each use, clean any residue from the welding wedge and pressure rollers using a non-abrasive cloth. Ensure the machine is cool before cleaning.
• Inspection: Periodically inspect the power cord for damage, and check the pressure rollers and welding wedge for wear.
• Storage: Store the machine in a dry, clean environment, away from direct sunlight and extreme temperatures.
