Feature:1. [High Efficiency] Induction heater uses electromagnetic fields to heat metals, faster, more accurate and efficient than oxygen acetylene systems. No open flames caused by heating, ensuring the safety.2. [High Brightness LED] Built in LED light at the end, which can provide bright lighting even when working in the dark, allowing you to have a clearer understanding of work progress and the status of heated objects.3. [10 Different Coils] Including 2 x 0.79in (dia20mm), 2 x 0.98in (dia25mm), 2 x 1.18in (dia30mm), 1 x 1.38in (dia35mm), 1 x 1.57in (dia40mm), 2 x free coils with a length of 29.53in (750mm), can adapt to various work needs.4. [3mm Brass Core] Made of brass wire with 3mm brass core, more reliable, can be heated to a high temperature of 800 for a long time, with good power saving effect that can achieve over 30%.5. [Cooling System] The flameless heat tool is equipped with cooling fan and overheating protection, which heats without damaging nearby thermal sensors and prolongs the service life.6. [Widely Used] Magnetic induction heater is mainly used to heat nuts and rusty screws to loosen them. Can also be used for heat treatment of automobiles, machinery, various small metal parts such as gears, pulleys, bearings, etc.Specification:Item Type: Magnetic Induction HeaterMaterial: Flame retardant ABS, brassModel: FH 1200Energy Saving Effect: Energy saving can achieve over 30%Working Frequency: 50-60HzRated Power: 1200WHeating Temperature: 800Time Required for Heating at 800: 5-40 seconds (the larger the object, the longer the time required)Heating Bolt Diameter: The coil can be wrapped and adjusted freelyAmbient Temperature: -40 to 60Relative Humidity:
