Feature: 1. [HIGH EFFICIENCY] Our induction heater uses electromagnetic fields to heat, which is faster, more accurate and efficient. There is no open flame caused by heating, ensuring your safety. 2. [LED LIGHT] The end of this heater is designed with LED light, which can provides lighting when working in the dark, you can clearer understand the work progress and the status of heated objects. 3. [6 COILS] Including 1 x 0.79in (dia20mm), 1 x 0.98in (dia25mm), 1 x 1.18in (dia30mm), 1 x 1.38in (dia35mm), 1 x 1.57in (dia40mm), 1 x free coils with a length of 29.53in (750mm), can adapt to various work needs. 4. [3mm BRASS CORE] The coil adopts 3mm brass core, more reliable, can be heated up to 800?? for a long time, with good energy saving effect that can achieve over 30%. 5. [OVERHEAT PROTECTION] Equipped with cooling fan and overheating protection, our induction heater can heat without damaging nearby thermal sensors, extends the service life. 6. [WIDELY APPLICABLE] The magnetic induction heater is mainly used to heat nuts and rusty screws, suitable for automobiles, machinery, and various small metal parts such as gears, pulleys, bearings, etc. Specification: Item Type: Magnetic Induction Heater Kit Material: Flame retardant ABS, brass Model: FH 1500 Energy Saving Effect: Energy saving can achieve over 30% Working Frequency: 50-60Hz Rated Power: 1500W Heating Temperature: 800??
