Feature: 1. [High Efficiency] Induction heater uses electromagnetic field to heat metal, which is faster, more accurate and more efficient. No open flame caused by heating, ensuring your work environment is safe. 2. [High Illumination Work Area LED] The induction heater has a built in LED light at the end, providing work area illumination even when working in the dark. You can get a clearer picture of the work progress and know the status of the object being heated. 3. [Box and 3 Coils] The magnetic induction heater kit comes with its own box, which is sturdy and durable, so you can always carry it with you when you are working outside. Equipped with 3 different sizes of coils, 3 pieces of coils include, 1 piece with 0.79in (20mm) diameter, 1 piece with 0.98in (25mm) diameter, 1 piece with 1.18in (30mm) diameter. 4. [3.0mm Brass Core] Induction coil heater kit is all made of brass wire with 3.0mm brass core, which is more reliable than 2.5mm brass core coils on the market, and can heat up to 800℃ high temperature for a long time with good power saving effect. 5. [Cooling System] The magnetic induction heater is equipped with cooling fan and overheat protection to heat up without damaging the nearby heat sensitive components, and the enhanced thermally stable thermoplastic housing improves the durability of the interior and exterior. 6. [Widely Used] Magnetic induction heater is 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: electromagnetic induction heater Material: flame retardant ABS, brass Power saving effect: power saving up to 30% or more Operating frequency: 50-60Hz Rated power: 1500W Heating temperature: 800℃ Heating 800 ℃ time required: 5-30 seconds (the larger the object the longer the time required) Heating bolt diameter: the coil can be set, the coil can be freely adjusted Ambient temperature: -40-60 ℃ Relative humidity:
