SEQURE SI012 Soldering Iron Body (Host)

Please note:  This item is is just the replacement body should you need a spare one or replacement.

So you’ve cooked your old FPV soldering iron, snapped a tip mid-build, or just want a cleaner portable soldering iron setup. Enter the SI012 soldering iron body—a lightweight, modular smart soldering iron handle built for drone soldering, SMD rework, and anyone tired of fighting dodgy irons. It supports T12 tips, TS tips, and SI series tips, runs off PD3.0 / QC power, and gives you actual control via a crisp OLED display. Yes, it’s just the “host”—because sometimes you don’t need another tip, you need competence. We’ve spent 10+ years shipping FPV gear, and trust us: most soldering problems aren’t skill issues… they’re tool issues.

Key Highlights

• Universal Tip Support: Compatible with T12, TS, and SI series tips for maximum flexibility.
• Smart OLED Control: 128×32 screen with adjustable temperature from 50°C to 450°C.
• Flexible Power Input: Supports PD3.0, QC2.0, DC5525 (9V–25V), and 3S–6S battery setups.

Why You Want It

This is the part you actually hold—the brains and backbone of your iron. If your current setup feels like soldering with a heated brick, the SI012 host fixes that. Lightweight, fast-heating, and properly configurable, it lets you dial temps for delicate SMD work or crank it up for XT60 joints without guessing. The sleep mode saves your tips (and your wallet), while the adjustable screen stops you twisting your wrist like a pretzel mid-build. It’s not glamorous—but neither is redoing cold joints at 2am before a race.

FAQ

Does this include a soldering tip?

No. This is the host/handle only. Bring your own T12, TS, or SI tip—or keep pretending your missing tip is “on order.”

What power source should I use?

Anything from USB-C PD to a 3S–6S LiPo works. For proper performance, use a stable PD3.0 supply or a capable battery setup.

Is this good for FPV drone builds?

Yes. It’s designed for FPV soldering, SMD repairs, and general electronics work where precision and portability matter.

Can I use this as a replacement for my existing SI012?

Exactly. If your original handle gave up (RIP), this is the direct replacement core unit.
