4. Setup and Component Identification
4.1 Hot Melt Machine
The hot melt machine, also referred to as the electric soldering iron, is the heating element for welding. It consists of:
- Electric Iron Head: The heating surface that melts the belt ends.
- Sleeve: Protects the internal wiring and provides structural support.
- Insulation Handle: Designed for safe and comfortable gripping during operation.

4.2 High-Precision Round Belt Connector
The connector holds the belt ends securely in place during the welding process. It features:
- Large V-groove: Suitable for connecting triangle belts or 8mm-30mm round belts.
- Small V-slot: Designed for connecting 2mm-8mm round belts.
- Positioning Pin: Ensures precise alignment of the belt ends.

4.3 Multi-Angle Cutting Scissors
The scissors are used for preparing the belt ends for welding. Key features include:
- Rubberized Handle: Provides a comfortable and secure grip.
- Clear Dial: Allows for easy adjustment of cutting angles (45-135 degrees).
- Fixed Lock: For safe and convenient storage.
- Blade: Designed for sharp and precise cutting.

5. Operating Instructions
Follow these steps for effective welding of PU round belts:
- Prepare the Belt: Use the multi-angle cutting scissors to cut the ends of the round belt flat and straight. This ensures a clean joint.
- Secure the Belt in Connector: Place the cut ends of the round belt into the appropriate V-groove of the connector. Ensure the ends are aligned precisely and fixed securely.
- Melt the Belt Ends: Plug in the hot melt machine (soldering iron) and allow it to reach its operating temperature, typically between 180-200°C. Carefully bring the heated iron head into contact with both belt ends simultaneously until they begin to melt. The connector is made of high-temperature resistant metal, ensuring a good hot-melt effect. The temperature of the hot melter should be within 250 degrees.
- Join and Cool: Once the belt ends are sufficiently melted, remove the hot melt machine and quickly bring the two melted ends together by tightening the connector. Hold the connector firmly for 2-3 minutes to allow the joint to cool and solidify completely.

5.1 Weldable Materials
This machine is suitable for welding a wide range of fusible materials, including:
- V-belts
- Pentagonal belts
- PU round belts
- PU pipes
- Rubber strips
- Other fusible plastic products
6. Maintenance
- After each use, ensure the hot melt machine has cooled down completely before cleaning.
- Wipe the electric iron head and connector with a clean, dry cloth to remove any residue.
- Store all components in a dry, clean place, away from direct sunlight and moisture.
- Regularly inspect the power cord for any signs of damage.
7. Troubleshooting
- Poor Weld Quality: Ensure the belt ends are cut flat and clean. Verify the hot melt machine has reached the correct operating temperature (180-200°C). Ensure sufficient melting time and firm pressure during cooling.
- Belt Not Holding in Connector: Check that the correct V-groove size is selected for the belt diameter. Ensure the positioning pins are properly engaged.
- Machine Not Heating: Check the power connection and ensure the outlet is functional. If the issue persists, discontinue use and contact support.
