2. Attaching the Soldering Tip
- Ensure the soldering pen is off and completely cool.
- Carefully screw the desired soldering tip into the threaded end of the soldering pen. Do not overtighten.
- Ensure the tip is securely seated for proper heat transfer.
3. Inserting the Battery
- Align the charged USB Lithium battery with the battery compartment at the base of the soldering pen.
- Slide the battery into the compartment until it clicks securely into place.
Operating Instructions
1. Powering On/Off
- To turn on, press and hold the power button located on the pen handle until the indicator light illuminates.
- The pen will begin to heat up. It reaches 900°F in under 2 minutes.
- To turn off, press and hold the power button again until the indicator light extinguishes.
2. Using the Work Light
- The soldering pen features an on-board work light to illuminate your work area. This light activates automatically when the pen is powered on.
3. Auto Shut-Off Features
- Tip Cover Auto Shut-Off: Placing the tip cover over the hot tip will automatically shut off the soldering pen for safe storage.
- Idle Auto Shut-Off: The soldering pen will automatically shut off after 10 minutes of inactivity to conserve battery and enhance safety.
4. Soldering Techniques
- Ensure the soldering tip is clean and tinned (coated with a thin layer of solder).
- Apply the hot tip to the components or wires to be joined, heating them simultaneously.
- Once the components are hot enough, apply solder to the joint, not directly to the tip. The solder should flow smoothly into the joint.
- Remove the solder, then remove the soldering pen. Allow the joint to cool undisturbed.

Maintenance
1. Cleaning the Soldering Tip
- Regularly clean the soldering tip using a damp sponge or brass wool to remove excess solder and oxidation. A clean tip ensures efficient heat transfer.
- Re-tin the tip after cleaning by applying a small amount of fresh solder.
2. Battery Care
- Store the battery in a cool, dry place away from direct sunlight and extreme temperatures.
- Do not store the battery completely discharged for extended periods. Charge it periodically if not in use.
- Avoid dropping or physically damaging the battery.
3. Storage
- Ensure the soldering pen is turned off and completely cool before storing.
- Place the tip cover over the soldering tip for protection and to activate the auto shut-off.
- Store the tool and battery in a dry, secure location, out of reach of children.
