Safety Instructions
WARNING: Failure to follow these safety instructions may result in electric shock, fire, or serious injury.
- Always operate the desoldering iron in a well-ventilated area to avoid inhaling fumes, especially during initial use when some smoke may be emitted.
- Ensure the power supply matches the device's requirements (110V).
- Do not leave the device unattended when plugged in or hot. Unplug the device when not in use or before performing maintenance.
- The desoldering iron tip and nozzle reach high temperatures (up to 400°C / 752°F). Avoid direct contact with skin or flammable materials.
- Use appropriate personal protective equipment, including safety glasses, to protect against splashes of molten solder.
- Do not use the device near water or in damp conditions.
- Keep out of reach of children.
- Ensure the device is completely cool before replacing nozzles or performing any cleaning.
- This device is intended for electronics repair and assembly. Do not use it for purposes other than desoldering.
Product Components
Familiarize yourself with the parts of your Preciva 929D-V desoldering iron:
Figure 2: Labeled components of the Preciva 929D-V Electric Desoldering Iron.
- Nozzle (Interchangeable): The tip that heats and contacts the solder joint. Two sizes (1.0mm & 1.2mm) are included.
- Heating Element: Located within the nozzle assembly, responsible for melting solder.
- Heat Deflector: Protects the handle from excessive heat.
- Storage Tube (Removable): Collects removed solder.
- Release Button: Activates the vacuum suction.
- Piston Rod: Part of the vacuum mechanism, pressed to prime the suction.
- Heating Indicator: Light that indicates the device is heating or has reached operating temperature.
- Guard Wire: Provides strain relief for the power cable.
- Power Cable: Connects the device to a 110V power outlet. Length: 140cm (55 inches).

Included Accessories:
- Desoldering Iron (main unit)
- Desoldering Nozzles (1.0mm and 1.2mm)
- Cleaning Needle
- Stand (for safe placement when hot)
- Built-in Gaskets (two spare gaskets are included for maintenance)
Setup
- Unpack: Carefully remove all components from the packaging. Inspect the device for any signs of damage.
- Select Nozzle: Choose the appropriate nozzle size (1.0mm or 1.2mm) for your application. The nozzles are interchangeable. Ensure the device is cool before changing nozzles.
- Placement: Place the desoldering iron on its included stand on a stable, heat-resistant surface.
- Ventilation: Ensure your workspace is well-ventilated.
- Power Connection: Plug the power cable into a standard 110V AC outlet. The heating indicator light will illuminate.
- Preheat: Allow the desoldering iron to preheat for approximately 3 minutes. The heating indicator light will show when it's ready for use.
Operating Instructions
The Preciva 929D-V is designed for one-handed continuous desoldering. Follow these steps for effective solder removal:
Figure 4: Step-by-step guide for operating the desoldering iron.
- Prepare the Device: Connect the power supply and allow the desoldering iron to warm up for about 3 minutes until the heating indicator shows it's ready.
- Prime the Suction: Press the piston rod down until it locks into place. This action primes the internal vacuum pump.
- Melt the Solder: Align the heated nozzle directly over the solder joint you wish to remove. Allow the solder to fully melt.
- Activate Suction: While the solder is molten, press and hold the release button. The vacuum pump will activate, sucking the molten solder into the storage tube.
- Remove and Repeat: Remove the desoldering iron from the joint. If necessary, repeat steps 2-4 until all solder is removed from the joint.
- Empty Solder: After cooling, unscrew and remove the storage tube to empty the collected solder.

Tip: For stubborn solder joints, adding a small amount of fresh solder can help improve heat transfer and make removal easier.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your desoldering iron.
Cleaning the Nozzle and Storage Tube
- Cool Down: Always ensure the desoldering iron is completely cool before cleaning.
- Empty Solder: Unscrew and remove the storage tube. Carefully tap out any accumulated solder.
- Clean Nozzle: Use the provided cleaning needle to clear any blockages in the nozzle. Insert the needle through the tip and gently push to remove debris.
- Clean Storage Tube: If necessary, use a small brush or compressed air to clean the inside of the storage tube.
- Reassemble: Reattach the storage tube securely.

Replacing Nozzles
Nozzles are consumable parts and may need replacement due to wear or clogging. Ensure the device is completely cool before attempting to replace the nozzle.
Figure 8: Replacing the desoldering nozzle.
- Cool Down: Allow the desoldering iron to cool completely.
- Unscrew: Carefully unscrew the old nozzle from the heating element assembly.
- Install New Nozzle: Screw on the new nozzle firmly but do not overtighten.
Replacing Gaskets
If you notice a decrease in suction power, the internal gaskets may be aging and require replacement. Two spare gaskets are included with your device.
- Disassemble: Refer to the product diagram to locate the internal gaskets. Carefully disassemble the relevant sections of the desoldering iron.
- Replace: Remove the old gaskets and replace them with the new ones.
- Reassemble: Carefully reassemble the device, ensuring all parts are securely fitted.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not heat up. | No power, faulty heating element, loose connection. | Check power outlet and cable. If still not heating, contact support. |
| Weak or no suction. | Nozzle clogged, storage tube full, worn gaskets, piston rod not primed. | Clear nozzle with cleaning needle. Empty storage tube. Replace gaskets if worn. Ensure piston rod is fully pressed before use. |
| Solder not melting effectively. | Insufficient preheating time, dirty nozzle tip, incorrect technique. | Allow full 3 minutes preheat. Clean nozzle tip. Ensure full contact with solder joint. Add fresh solder to aid heat transfer. |
| Device smokes excessively on first use. | Manufacturing residues burning off. | This is normal for initial use. Operate in a well-ventilated area until smoke subsides. |
| Handle becomes too hot. | Prolonged continuous use, faulty heat deflector. | Allow the device to cool periodically during extended use. If the issue persists, contact support. |
