Features: 1. Using a 0.99-inch TFT color screen, it can simultaneously display on the main screen: temperature gear status, set temperature, power supply voltage, internal temperature, actual temperature of the heating core, power percentage, etc. 2. The maximum power is up to 100W, with extremely fast heating and temperature recovery speed. 3. The all-aluminum alloy CNC shell is beautiful, sturdy and practical. The heating core has good contact and not shake during welding. 4. Multiple sets of commonly used temperatures can be preset, and quick temperature adjustment is not time-consuming. Vibration wake-up, automatic shutdown, multiple adjustable parameters and other rich functions. Our equipment has a complete function of limiting the maximum power. The input voltage and maximum working power can be set manually, which can effectively prevent incompatibility/flash screen/restart problems caused by low resistance of the heating core and low power of the charger. Specifications: Name: Electric Soldering Iron Display: 0.99inch TFT color screen Adjustment mode: 3 buttons Temperature ranges: 50-500℃ Power: 100W max Temperature stability: ± 3℃ Heating core storage parameters: 4 groups Common temperature storage group: 4 groups Color: Black Material: Aluminum Alloy Notes: 1. The default setting of the decoy voltage is 20V. If the voltage of the charger used does not reach 20V, the machine have screen flickering, etc. Please and hold the middle button to restart the machine and enter the menu settings to enter the power limit ratio settings. 2. If the machine prompts that the heating core is not detected, please check whether the heating core is fully inserted or whether the heating core is contaminated with foreign matter and causes poor contact. The actual object may have color difference due to different light or display Package Contents:
