7s Fast Heating & 5°C Precision Control: Our 120W Soldering iron reaches its full heat of 356-968°F in just 7 seconds to reduce the waiting time, making it ideal for delicate electronics and heat-sensitive components. Can be adjusted accurately and efficiently for different repair jobs, so as not to damage heat-resistant components.

Smart Dual-Chip Technology for Safety & Consistency: Our professional 120W soldering iron is built in Industrial-grade MCU chip and Gravity sensor chip. MCU precisely controls the constant temperature and our soldering iron is perfect for who wants professional quality for heavy-duty applications that require fast heat.

Auto Sleep Mode: Gravity sensing chip controls SLEEP mode. After stopping working for 30 seconds, the electric soldering iron will enter sleep mode, the screen shows" SLP". Our led soldering iron will automatically restart to heat up to the temperature you set when picking it up again.

Automatic shutdown function: If our soldering iron will be idle for 15 minutes and it will automatically turn off to save your energy and your time. Includes easy °C to °F conversion, Sleep Mode, and Digital Temperature Calibration.

Enhanced Cooling with Unique 6 Ventilation Holes Design : Our soldering iron features semi open heat dissipation structure for better heat dissipation, reducing the temperature conducted from the solder tip to the handle.

2 YEARS Quality Guarantee: We guarantee against soldering gun faulty materials and workmanship for 24 months – giving you total peace of mind. If there is any issue within 24 months of your purchase, we will replace it for you with no doubt.

Larger LED Digital Display: A high-definition LED screen display indicates the temperature status more clearly, so you don’t need to worry about finding the right temperature for each welding job. Our soldering iron features a ON/OFF Switch for energy savings and safer operation.
