Feature:1. High Working Efficiency: This handhled electromagnetic induction heater utilizes an electromagnetic field to heat metal faster, more accurately, and more efficiently than an oxyacetylene system.2. Built In LED Light: This induction heat bolt removal tool has a built in LED light at the end, which provides illumination of the work area even when working in the dark, allowing for a clearer understanding of the progress of the work and the status of the object being heated.3. 6 Different Coil Sizes: This heat induction tool comes with 6 different coil diameter sizes, 1PCS 0.79in (20mm), 1PCS 0.98in (25mm), 1PCS 1.18in (30mm), 1PCS 1.38in (35mm), 1PCS 1.57in (40mm), 1PCS length 29.53in (750mm) free coil, multiple coil models and sizes can be adapted to the work requirements in many ways, making your workflow smoother.4. 3.0mm Brass Core: This handheld rusty screw removing tool is made up of brass wires with 3.0mm brass core, which can be heated up to 800 high temperature for a long time without fear of high temperature test.5. Safe And Reliable: This mini induction heating machine is safe and reliable, equipped with a cooling fan and over temperature guard to extend the life of the unit by heating without damaging nearby thermal elements. The enhanced heat stabilized thermoplastic housing improves durability both internally and externally.Specification:Item Type: Heat Induction ToolMaterial: Flame Retardant ABS, BrassModel: FH-1200Power Saving Effect: Power Saving Up to 30% or MoreOperating Frequency: 50-60HzRated Power: 1200WHeating Temperature: 800Heating Time for 800: 5-40 Seconds (Larger objects may require longer time.)Heating Bolt Diameter: Coils are adjustable and can fit around the bolt.Operating Temperature: -40-60Relative Humidity:
