Feature: 1. SPECIFICATIONS: Including an electromagnetic induction heater with 20mm, 25mm, 30mm, 35mm, 40mm, 750mm free coil, different models meet more work needs, simple and practical. 2. WORKING PRINCIPLE: Induction heating tool uses electromagnetic field to heat metals, with high efficiency and accuracy, without open flames caused by heating, ensuring a safe working environment. 3. WITH LED LIGHT: The heater has built in LED light at the end, which can provide lighting for dark working areas and clearly understand the work progress and object heating status. 4. 3.0MM BRASS CORE: These induction coils are composed of brass wires with 3.0mm brass core, which can be heated to a high temperature of 1200??, corrosion and heat resistance. 5. COOLING SYSTEM: Equipped with cooling fan and overheating protection, heating can be done without damaging nearby thermal sensors, extending the service life of the equipment. 6. WIDE APPLICATION: Mainly used for heating nuts and rusty screws to loosen them, can also be used for heat treatment of automobiles, machinery, and various metal parts such as gear, pulley, bearing, etc. Specification: Item Type: Induction Heater Model: FH 1000 Maximum Output Current: 150A Working Frequency: 50-60Hz Rated Power: 1800W Heating Temperature: 1200?? Heating Time at 1200??: 5-40 Seconds (the larger the object, the longer the time required) Heating Bolt Diameter: The coil can be covered and adjusted freely Ambient Temperature: -40-60??
