Feature: 1. HIGH WORK EFFICIENCY: Induction heating tools use electromagnetic fields to heat metals, which is faster, more accurate, and more efficient than oxygen acetylene systems. No open flames caused by heating, ensuring the safety of your work environment. 2. HIGH ILLUMINATION WORK AREA (LED): The induction heater bolt is disassembled and the built in LED light is installed at the end, providing illumination for the work area even when working in the dark. It can provide a clearer understanding of the work progress and the state of the heated object. 3. TOOLBOX AND 8 COILS: The magnetic induction heater set comes with its own toolbox, which is sturdy, durable, and cool and beautiful. You can always carry it with you when working outside, while keeping your studio neat and orderly. Equipped with 8 different sizes of coils, including 2 coils 0.79in (20mm), 2 pieces 0.98in (25mm), 2 pieces 1.18in (30mm), 2 free coils with a length of 29.53in (750mm), various coil models and sizes can adapt to work needs in various ways, making your workflow smoother. 4. 3.0MM BRASS CORE: The induction heater kit is composed of brass wires with a 3.0mm brass core, which is more reliable than 2.5mm brass core coils on the market. It can be heated to a high temperature of 800 ?? for a long time and is not afraid of high temperature tests. Compared with the electric heating coils currently used in the market, the power saving can arrive over 30%. 5. COOLING SYSTEM: The flameless heating tool for automobiles is equipped with a cooling fan and overheating protection, which heats without damaging nearby thermal sensors and prolongs the service life of the equipment. The enhanced thermally stable thermoplastic shell enhances both internal and external durability. 6. WIDELY USED: Magnetic induction heaters are mainly used to heat nuts and rusty screws to loosen them. It can also be used for heat treatment of automobiles, machinery, and various small metal parts such as gears, pulleys, bearings, etc. Specification: Item Type: Rusty Screw Nut Induction Heater Mode: FH 1500B Material: Flame Retardant ABS, Brass, Aluminum Alloy Power Saving Effect: Power saving can arrive over 30% Working Frequency: 50-60Hz Rated Power: 1500W Heating Temperature: 800 ?? Time Required for Heating at 800 ??: 5 to 30 seconds (the larger the object, the longer the time required) Heating Bolt Diameter: The coil can be covered and adjusted freely Environmental Temperature: -40 ?? to 60 ?? Relative Humidity: Less than 95% RH Atmospheric Pressure: 86KPa to 100KPa Function: 1. Equipped with soft start function, long service life in case of frequent starts. 2. Equipped with IGBT overcurrent protection function. 3. Equipped with input and output overcurrent protection automatic adjustment negative feedback function. 4. Equipped with IGBT over temperature protection function. 5. Equipped with heating coil short circuit protection function. 6. Equipped with heating coil open circuit protection function. 7. Full bridge series resonant circuit topology with strong anti interference ability. 8. Using high performance IGBT driver chips for accurate driving and output waveforms. 9. Automatic identification of load and phase locked function to achieve high power factor at the load end, and to enable circuit control to work efficiently in weak inductive areas. 10. Several electromagnetic heating controllers are installed in parallel on the same heating tube without interfering with each other. 11. P ower Saving Effect: Compared with the currently used electric heating coils, the power saving can arrive over 30%. 12. Easy Installation: can be connected to induction coils with bucket and flat plate structures, etc. Coils: 2 x 0.79in (20mm), 2 x 0.98in (25mm), 2 x 1.18in (30mm), 2 x coils with a length of 29.53in (750mm).
