Feature:1. High Work Efficiency: This induction heater uses electromagnetic fields to heat metals, ensuring faster, more accurate, and more efficient operation. No open flames caused by heating, ensuring a secure working environment.2. LED Light Design: The handheld induction heater has built in LED light at the end, providing illumination for dark work areas. It can provide a clearer understanding of the work progress and the status of the heated object.3. 10 Heating Coils: This kit includes 2 pieces 0.79in (20mm), 2 pieces 0.98in (25mm), 2 pieces 1.18in (30mm), 1 piece 1.38in (35mm), 1 piece 1.57in (40mm), 2 free coils with a length of 29.53in (750mm). Multiple models and sizes are suitable for different work needs.4. 3.0mm Brass Core Wire: These induction coils are composed of 3.0mm brass core and wire, which can be heated to a high temperature of 800 for a long time, which is efficient and reliable. Energy savings of over 30%.5. Secure Operation: The magnetic induction heater is equipped with cooling fan and overheating guard, which heats up without damaging nearby thermal components, extending the service life. Thermoplastic shell enhances internal and external durability.6. Wide Application: This magnetic induction heater is mainly applied to heat rusted nuts and screws to loosen them. It is also applied to the heating of automobiles, machinery, and various small metal parts such as gears, pulleys, bearings, etc.Specification:Item Type: Magnetic Induction HeaterModel: FH-1200Energy Saving Effect: Up to 30%Working Frequency: 50-60HzRated Power: 1200WHeating Temperature: 800800 Heating Time Required: 5-40 seconds (larger objects may require longer time)Heating Bolt Diameter: Coil can be wrapped around, coil can be freely adjustedAmbient Temperature: -40-60Relative Humidity:
