Power: 90W Heating Element: Professional PCB Ceramic Core Stable Temperature: ±5 degrees (no load) Adjustable Temperature: 100°C-480°C/212°F-896°F Tin Melting Time: <1 minute Sleep Time: 15 minutes Power Cord Length: 1.43 m Iron Length: 232 mm Multimeter Battery: 9V (not included) Features: Multimeter: Easy-to-use digital multimeter for measuring DC and AC voltage, DC and AC current, resistance, diode, and continuity tests. Features data hold and reading functions on a large LCD screen. 5 Soldering Tips: Five different tips allow for easy installation of the soldering iron for guitars, computers, hardware, capacitors, TV accessories, etc. Metal Soldering Iron Stand and Cleaning Sponge: The portable soldering iron stand with a cleaning sponge securely holds the soldering iron for safety and convenience, preventing burns or injuries. Desoldering Pump: Composed of a high-pressure vacuum tube and an aluminum frame, this pump allows for one-handed operation. It can absorb large amounts of solder, while solder wire is better for absorbing small amounts of welding. Durable and Practical Bag: Various tools are conveniently housed in a durable, easy-to-carry PU bag, keeping all components organized and making them easy to store and transport anywhere. Widely Used: Essential tools widely used for soldering projects, DIY home work, electrical and electronic appliance repairs, circuit board soldering, other DIY soldering applications, craft/jewelry making, and more. Soldering Tips and Techniques: Always exercise caution when using these tools. Refer to safety tips when working with soldering irons, soldering, and related activities. Select an appropriate temperature for soldering. Lower the temperature or turn off the soldering iron when not in use for extended periods (do not leave it idle) to prevent damage to the iron and malfunctions.
