Digital Soldering Iron Kit — Professional-Grade Power & Precision

Upgrade your workbench with the Lefavor Digital Soldering Iron Kit, available in 100W, 120W, and 150W models. Engineered for electronics enthusiasts, hobbyists, and professionals alike, this electric soldering iron delivers fast heat-up times, a wide temperature range, and a dual-key calibration system — so you always work with confidence and accuracy.

Key Features

• Multiple Power Options: Choose from 100W (180–520°C), 120W (200–600°C), or 150W (200–600°C) configurations to match your project demands.
• Wide Temperature Range: Adjustable from 180°C up to 600°C, giving you precise control for delicate PCB work or heavy-duty soldering tasks.
• Dual Calibration Function: Simply long-press the up and down keys simultaneously to access the dual temperature calibration mode — two independent calibration settings for maximum versatility (907S2 series).
• Ceramic Plug-In Heating Core: The plug-in ceramic heating element (220V resistance: 270Ω) ensures rapid, stable, and consistent heat delivery.
• Dual Voltage Compatibility: Supports both 110V (US plug) and 220V (EU plug) — please select the correct voltage for your region at checkout.
• Compatible Tip System: Uses standard 907 series soldering iron tips, widely available and easy to replace.
• CE & FCC Certified: Meets recognized safety and electromagnetic compatibility standards for peace of mind.
• Ergonomic, Compact Design: Measures just 29 × 5 × 3 cm and weighs approximately 0.15 kg — comfortable to hold during extended use.
• Compatible Models: 907, 907S, 907S2, 909, 919 Series electric soldering irons.

Frequently Asked Questions

Q: What is the difference between the 100W, 120W, and 150W soldering iron models?

A: The 100W model (907S series) operates in the 180–520°C range, making it ideal for standard electronics work. The 120W and 150W models (909/919 series) reach up to 600°C and are suited to heavier-duty soldering tasks requiring more thermal mass and faster recovery times. All models feature the dual-key temperature calibration system.

Q: How does the dual temperature calibration work on this digital soldering iron?

A: Simply long-press both the up (▲) and down (▼) keys at the same time to enter calibration mode. The 907S2 series supports two separate calibration offsets, allowing you to fine-tune the displayed temperature to match your actual tip temperature for consistent, accurate results.

Q: Which plug type should I choose — 110V or 220V?

A: If you are in the United States or Canada, select the 110V US plug version. If you are in Europe, Australia, or another region using 220–240V mains power, select the 220V EU plug version. Using the wrong voltage can damage the unit, so please choose carefully at checkout.

Q: What soldering iron tips are compatible with this kit?

A: This soldering iron is compatible exclusively with 907 series soldering iron tips. These tips are widely available and come in a variety of shapes (conical, chisel, bevel, etc.) to suit different soldering applications.

Q: Is this soldering iron suitable for SMD and PCB work?

A: Yes. The precise digital temperature control and wide temperature range make this iron well-suited for surface-mount device (SMD) rework, PCB assembly, circuit board repairs, and general electronics projects. Use a fine 907 series tip for detailed SMD work.
