The AIYI 100W Hand-Held Automatic Soldering Gun combines an electric soldering iron with an integrated solder-wire feeding mechanism. Its pistol-style design allows the tool and solder feed to be controlled with one hand during compatible electrical, electronic and repair work.

A solder-wire reel mounts above the handle and feeds wire towards the heated tip when the trigger mechanism is operated. The packaging identifies the tool for compatible circuit-board work, appliance repair, home DIY projects and jewellery-related soldering applications.

How to Use

Read the supplied instructions before using the tool.
Work in a clean and well-ventilated area.
Wear suitable eye protection.
Place the tool on a stable, heat-resistant surface.
Confirm that the installed solder wire is suitable for the intended materials.
Check that the solder wire is routed correctly through the feed mechanism.
Clean and secure the components or wires being joined.
Connect the tool to a compatible electrical outlet.
Allow the soldering tip to heat fully.
Tin the tip if required for the selected solder and application.
Position the heated tip against the joint.
Operate the feed trigger gradually to deliver a controlled amount of solder.
Allow the solder to flow across the heated joint.
Release the feed mechanism and remove the tip.
Allow the joint to cool without movement.
Place the hot tool in a suitable heat-resistant holder between applications.
Disconnect the tool immediately after use.
Allow the tip and housing to cool completely before cleaning or storage.
Wash your hands thoroughly after handling solder wire.

Feed the solder gradually to avoid applying an excessive amount or causing molten solder to splash.

Compatibility / Applications

Suitable for compatible:

Electrical wire joints
Cable connections
Circuit-board soldering
Larger PCB joints
Electrical terminals
Appliance repairs
Electronics maintenance
DIY electrical projects
Hobby electronics
Component connections
Workshop repairs
Equipment maintenance
Automotive wiring repairs
Repetitive soldering tasks
Compatible jewellery and craft-metal soldering

Confirm that the 100W rating, fitted tip, solder-wire alloy and flux formulation are suitable for the intended joint and components. A 100W tool may supply more heat than delicate electronic components can safely tolerate.

This is a soldering tool and should not be treated as a structural welding machine.

Care & Maintenance

Disconnect the tool before cleaning, adjustment or inspection.
Allow the soldering tip to cool completely.
Keep the housing and feed mechanism clean and dry.
Wipe the exterior with a soft, dry cloth.
Keep the solder-wire path free from debris and hardened residue.
Clean and tin the tip according to the solder manufacturer’s recommendations.
Do not file or aggressively abrade plated soldering tips.
Replace worn, oxidised or damaged tips with compatible replacements.
Check the solder reel and feed mechanism before each use.
Do not force the trigger if the solder wire jams.
Inspect the power cord and plug regularly for damage.
Stop using the tool if its housing, cable, trigger or electrical components are damaged.
Store in a cool, dry and well-ventilated location.
Keep solder wire clean and protected from contamination.
Store away from children, food and drinks.

FAQs

What is the power rating?
The packaging identifies the soldering gun as a 100W model.

What is the model number?
The model number visible on the packaging is AY149-005.

How does the automatic feed work?
Solder wire is supplied from the top-mounted reel and advanced towards the heated tip using the trigger mechanism.

Can it be operated with one hand?
Yes. The packaging identifies it as a one-handed-use design.

Is solder wire included?
A solder-wire reel is shown mounted on the packaged tool. Its alloy, diameter and quantity are not visible.

Does it have temperature control?
Temperature adjustment is not clearly confirmed by the supplied image.

What voltage does it use?
The voltage rating is not visible in the supplied image. Confirm it on the tool, instructions or additional packaging before connecting it.

Is it suitable for circuit boards?
The packaging lists circuit-board work as an application. However, the 100W rating may be too powerful for delicate components, so confirm suitability before use.

Can it be used for appliance repair?
Yes, it may be used for compatible appliance wiring and electrical joints after confirming the required heat and solder type.

Is it a welding gun?
No. It is an electric soldering tool. Some packaging applications use the word “welding,” but the product is intended to melt solder rather than perform structural welding.

Are spare tips included?
Spare tips are not clearly shown as included.

Does it require a separate solder spool?
A top-mounted solder reel is shown on the tool. Replacement solder will be required when the supplied reel is depleted.
