Feature: 1. HIGH EFFICIENCY: Induction heating tools use electromagnetic fields to heat metals faster, more accurately and more efficiently than oxy acetylene systems. No open flame caused by heating to ensure your working environment safe 2. HIGH ILLUMINATION WORK AREA: Induction heater bolt removal with built in LED light at the end to provide working area lighting even in the dark. You can understand the work progress more clearly and understand the state of the heated object 3. TOOLBOX AND 3 COILS: The magnetic induction heater kit come with a toolbox that is rugged, cool and beautiful. You can take with you at all times when you are away working to keep your studio clean and organized. Equipped with 3 different sizes of coils, including 1 dia 0.79in(20mm), 1 dia 0.98in(25mm), 1 dia 1.18in(30mm), a variety of sizes can be adapted to work in a variety of ways, so that your work flow is smoother 4. 3.0MM BRASS CORE: The induction coil kit is made of 3.0mm brass wire, which is more reliable than the 2.5mm brass coil on the market, and can be heated to 800?? for a long time, not afraid of high temperature test. The power saving effect is good, the power saving can reach more than 30% compared with the electric heating coil used in the current market 5. COOLING SYSTEM: Automotive flameless heating tools are equipped with cooling fans and overheat protection to heat up without damaging nearby thermal elements, extending the service life of the equipment. Enhanced heat stable thermoplastic housing improves internal and external durability 6. WIDE APPLICATION: Magnetic induction heaters are 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, belts, bearings, etc. Specification: Item Type: Magnetic Induction Heater Kit Power Saving Effect: Power saving up to 30% Operating Frequency: 50 ~ 60Hz Rated Power: 1200W Heating Temperature: 800?? Heating Time of 800??: 5 ~ 40 Seconds(the larger the object, the longer the time) Heating Bolt Diameter: Coil can be covered, coil can be freely adjusted Ambient Temperature: -40?? ~ 60?? Relative Humidity:
