5. Operating Instructions
- Power On: Plug the soldering gun into a standard 120-volt AC outlet.
- Select Heat Setting: The gun features a dual-heat trigger.
- Press the trigger partially (first position) for 100 watts of heat.
- Press the trigger fully (second position) for 140 watts of heat.
- Soldering:
- Apply the hot tip to the joint to be soldered, ensuring both surfaces are heated simultaneously.
- Feed solder onto the heated joint, not directly onto the tip. The solder should flow smoothly and evenly.
- Remove the solder wire, then remove the soldering gun. Allow the joint to cool undisturbed.
- Duty Cycle Adherence: Remember to observe the 1 minute ON / 4 minutes OFF duty cycle to prevent damage to the tool.
- Power Off: Release the trigger to turn off the heating element. Unplug the tool from the outlet when finished or when not in use.

6. Maintenance
- Tip Cleaning: Regularly clean the soldering tip with a damp sponge or brass wool to remove excess solder and oxidation. A clean tip ensures efficient heat transfer.
- Tip Replacement: Tips will wear out over time. Replace them when they become pitted, corroded, or no longer hold solder effectively. Ensure the gun is unplugged and cool before replacing tips.
- General Cleaning: Keep the body of the soldering gun clean and free of dust and debris. Use a dry cloth for cleaning.
- Cord Inspection: Periodically inspect the power cord for any signs of damage. Do not use the tool if the cord is frayed or damaged.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gun does not heat up. | Not plugged in; faulty outlet; damaged cord; loose tip connection. | Check power connection; try a different outlet; inspect cord for damage; ensure tip screws are tight. |
| Solder does not melt or flows poorly. | Dirty or oxidized tip; insufficient heat setting; improper application. | Clean the tip thoroughly; ensure full trigger press for 140W; apply tip to joint, not solder. |
| Gun overheats or shuts off. | Exceeded duty cycle (1 min ON / 4 min OFF). | Allow the gun to cool down for at least 4 minutes. Adhere strictly to the recommended duty cycle. |
| Work light is dim or not working. | Bulb failure; electrical issue. | Contact Weller customer support for assistance. |
