Feature: 1. High Work Efficiency: This induction heater tool uses electromagnetic fields to heat metal, which is faster, more accurate, and more efficient, without any open flames caused by heating, ensuring the security of your work environment. 2. LED Auxiliary Lighting: The handheld induction heater has built in LED light at the end, providing auxiliary lighting when working in the dark, and clearly understanding the progress of work and the status of heating objects. 3. 4 Different Coils: Equipped with 4 different sizes of coils, including 20mm (0.79in) coil, 25mm (0.98in) coil, 30mm (1.18in) coil, and a 750mm (29.53in) free coil, various coil models and sizes are suitable for different work needs. 4. Brass Core Coil: These heat induction coils are made of 3.0mm brass core wire, which can be heated for a long time to a high temperature of 800??, efficient and reliable, and has a power saving effect of up to 30%. 5. Cooling System: The induction heater is equipped with cooling fan, with overheating protection, which heats up without damaging nearby thermal sensor, and the thermoplastic shell greatly extends the service life of the equipment. 6. Applicable Range: The induction heater coil kit is mainly used to heat rusty screws and nuts to loosen them, and suitable for heat processing of various metal parts such as gears, pulleys, and bearings in automobiles, machinery, and other industries.
