Feature:1. HIGH EFFICIENCY: Induction heater uses electromagnetic fields to heat metal, which is faster, more accurate and more efficient than oxygen acetylene systems. No open flames caused by heating, ensuring safety.2. LED LIGHT: The induction heater has built in LED light at the end, which can provide lighting for the work area even when working in the dark.3. 10 COILS: Including 2 pieces 0.79in (20mm), 2 pieces 0.98in (25mm), 2 pieces 1.18in (30mm), 1 piece 1.38in (35 mm), 1 piece 1.57in (40mm), 2 pieces 29.53in (750mm) length free forming coil.4. COOLING SYSTEM: Flameless heating tool is equipped with cooling fan and overheating protection, will not damage nearby thermal sensors. Enhanced thermally stable shell enhances both internal and external durability.5. WIDE PURPOSE: Magnetic induction heater is mainly used to heat nuts and rusty screws to loosen them, can also be used for automobiles, machinery, and various small metal parts such as gears, pulleys, bearings, etc.Specification:Item Type:Material: Flame Retardant ABS, BrassModel: FH 1000Maximum Output Current: 150AWorking Frequency: 50-60HzRated Power: 1800WHeating Temperature: 1200Time Required For Heating At 1200: 5-40 Seconds (Larger Objects Require Longer Time)Heating Bolt Diameter: For the coil can be wrapped, can be adjusted freelyAmbient Temperature: -40 to 60Relative Humidity:
