The SEQURE HT140 is a highly versatile 2-in-1 soldering tool that combines the functionality of hot tweezers and a soldering iron. It is specifically engineered for precise SMD soldering and desoldering tasks.
With independent control for single-sided heating, it operates as a traditional soldering iron when fitted with a standard tip. When configured for dual-sided heating, it transforms into hot tweezers – perfect for the efficient and accurate removal of SMD components.
Features
Working Temperature: 50-500°C (122-932°F)
Supports multiple power inputs: PD 3.1/3.0/2.0, QC 3.0/2.0, (5-28 V DC), LiPo batteries, and power adapters.
The HT140 combines hot tweezers and a soldering iron, with independent single- or dual-sided heating. Use it as a soldering iron with a tip, or as hot tweezers for easy SMD desoldering.
Voltage and current can be adjusted based on the power source.
Features dual temperature control, presets, quick temperature increase, and fine-tuning.
128 x 32 OLED screen with adjustable brightness, and orientation. Switchable °C/°F.
High-precision heating element with ±1% accuracy. Melts solder in just 2 seconds.
Smart standby, sleep, and wake-up functions extend tip lifespan and boost efficiency.
Supports temperature calibration and compensation for precise work.
Includes a 1.5 m heat-resistant PD 150 W silicone cable and a sturdy all-metal HT Station.
Swappable tips and adjustable angles for various SMD soldering tasks.
