Setup Guide
- Unpack the Device: Carefully remove the filament connector and all accessories from its packaging.
- Inspect for Damage: Check the device for any visible damage that may have occurred during shipping. If damaged, contact customer support.
- Placement: Place the filament connector on a stable, flat, and heat-resistant surface, away from flammable materials.
- Power Connection: Connect the power adapter to the device and then plug it into a suitable power outlet. The device will power on and display its current status.
Operating Instructions
Follow these steps to effectively join 1.75mm 3D printer filaments:
- Prepare Filaments: Ensure both ends of the filaments to be joined are cut cleanly and are free of debris.
- Connect Power: Plug in the device. The display will activate.
- Select Material and Temperature:
Use the control buttons to select the appropriate filament material (e.g., PLA, PETG, ABS). The device has preset temperatures for common materials. Refer to the temperature chart below for guidance.

- Insert PTFE Sleeve: Slide one of the provided PTFE sleeves onto one of the filament ends. This sleeve will protect the joint and provide structural integrity.
- Place Filaments: Open the top cover of the connector. Insert both filament ends into the designated slots, ensuring they meet precisely in the heating chamber. The PTFE sleeve should be positioned over the joint area.

- Initiate Heating: Close the cover. The device will begin heating to the selected temperature. Monitor the progress on the display.
- Filament Welding: Once the device reaches the target temperature and the melting time is complete (refer to the chart below), the filaments will be fused. The device may indicate completion.
- Remove Fused Filament: Carefully open the cover and remove the newly joined filament. Allow it to cool completely before handling or winding onto a spool.
Filament Compatibility and Temperature Settings
The following table provides recommended settings for various 1.75mm filament types:
| Wire Material | Default Melting Temp | Heating-up Time | Recommended Melting Time |
|---|---|---|---|
| PCL Series | 85°C | 1 min. | 5s to 6s |
| PLA Series | 185°C | 3 min. | 7s to 8s |
| ABS Series | 220°C | 3 to 4 min. | 7s to 8s |
| PETG Series | 210°C | 3 to 4 min. | 7s to 8s |
| PA/PC Series | 230°C | 5 min. | 9s to 10s |

Maintenance
- Cleaning: Ensure the device is unplugged and completely cool before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Heating Chamber: Periodically inspect the heating chamber for any filament residue. If necessary, gently remove any melted plastic with a non-metallic tool after the device has cooled.
- Storage: Store the filament connector in a dry, dust-free environment when not in use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Power cable not connected properly; Power outlet malfunction. | Check power cable connection; Try a different power outlet. |
| Filaments do not fuse properly. | Incorrect temperature setting; Insufficient melting time; Filaments not aligned correctly; Incompatible filament types. | Verify temperature and melting time according to the material chart; Ensure filament ends are clean and perfectly aligned; Confirm both filaments are of the same material type. |
| Filament sticks to the heating chamber. | Excessive melting time; Residue in chamber. | Reduce melting time slightly; Clean the heating chamber after it cools down. |
| Display shows an error message. | Internal malfunction. | Power cycle the device. If the error persists, contact customer support. |
