6. Setup
- Unpack: Carefully remove all components from the packaging.
- Select Tip: Choose the appropriate soldering tip for your task. Ensure it is securely fastened.
- Place in Stand: Always place the soldering iron securely in its stand when not actively soldering.
- Connect Power: Plug the power cord into a suitable electrical outlet matching the iron's voltage (110V or 220V).
- Power On: The iron will begin to heat up. For SL102, the digital display will show the current temperature.
- Adjust Temperature (SL102): Use the '+' and '-' buttons to set the desired temperature. Long press the buttons for continuous adjustment. The new setting will be memorized after 3 seconds of no button activity.
- Preheat: Allow the soldering iron to reach the set temperature. This typically takes 30-50 seconds after the heating core reaches the set temperature.
- Tin the Tip: Once heated, apply a small amount of solder to the tip to 'tin' it. This helps with heat transfer and prevents oxidation.

7. Operation
Follow these steps for effective soldering:
- Prepare Components: Ensure the components and PCB pads are clean and free of oxidation.
- Heat Joint: Place the hot soldering iron tip against both the component lead and the PCB pad simultaneously. Allow a few seconds for the joint to heat up.
- Apply Solder: Once the joint is hot enough, touch the solder wire to the joint (not directly to the iron tip). The solder should melt and flow smoothly around the joint, forming a shiny, cone-shaped connection.
- Remove Solder and Iron: Remove the solder wire first, then quickly remove the soldering iron. Avoid moving the component until the solder has solidified.
- Inspect Joint: Visually inspect the solder joint. It should be shiny, smooth, and cover both the component lead and the pad.
Desoldering Aids: The included 6-piece set of desoldering aids can assist in various tasks such as pulling, pressing, hooking, breaking, scraping, drilling, brushing, and prying components or solder from circuit boards.

8. Maintenance
- Tip Cleaning: Regularly clean the soldering iron tip using the included cleaning sponge (dampened, not soaking wet) to remove excess solder and oxidation. This ensures efficient heat transfer and prolongs tip life.
- Tip Tinning: After cleaning and before storing, re-tin the tip with a small amount of fresh solder to prevent oxidation.
- Tip Replacement: The soldering iron tips are replaceable. To change a tip, ensure the iron is cool and unplugged. Rotate the stainless steel sleeve counter-clockwise to loosen and remove the old tip. Insert the new tip and tighten the sleeve clockwise.
- Storage: Allow the soldering iron to cool completely before storing it in the provided storage bag.
- General Cleaning: Keep the body of the soldering iron clean and free from dust and debris. Use a soft, dry cloth.

9. Troubleshooting
- Product Not Operating Properly: If the product is not functioning as expected, ensure it is correctly plugged in and the power supply matches the device's requirements. Check for any visible damage to the cord or iron.
- Temperature Issues: If the iron is not heating or maintaining temperature, ensure the tip is clean and properly seated. For SL102, verify the temperature setting on the digital display.
- Poor Solder Joints: This can be caused by an unclean tip, insufficient heat, or improper solder application. Ensure the tip is tinned, the temperature is adequate for the solder type, and you are heating both the component and pad before applying solder.
- Artificially Damaged Product: Damage resulting from improper use, incorrect voltage, or unauthorized modifications is not covered under standard support. Always follow the instructions in this manual.
10. User Tips
- For precise temperature control, opt for the SL102 model with its digital display.
- Always ensure your soldering iron's voltage matches your local power supply. If not, use a step-up/step-down transformer.
- Utilize the variety of soldering tips provided for different tasks; fine tips for small components, broader tips for larger pads or desoldering.
- Keep your soldering iron tip well-tinned and clean with the damp sponge to maximize its lifespan and performance.
- The included desoldering aids are very useful for removing components or cleaning up solder bridges on circuit boards.
