Feature: 1. [High Efficiency and Accurate] Induction heater adopts electromagnetic field to heat metal, faster, more accurate and more efficient. No open flame caused by heating, ensuring your work environment is safe. 2. [LED] The induction heater has a built in LED light at the end, providing work area illumination even when working in the dark. You will get a clearer feel of the work progress and know the status of the object being heated. 3. [10 Coils] This induction heater kit adopts 10 coils, 2pcs diameter 0.79in 20mm, 2pcs diameter 0.98in 25mm, 2pcs diameter 1.18in 30mm, 1 diameter 1.38in 35mm, 1 diameter 1.57in 40mm, 2pcs length 29.53in 750mm free coils. 4. [3.0mm Brass Material Core] Induction coil nut screw heater kit is all made of brass wire with 3.0mm brass core, and can heat up to 800℃ high temperature for a long time with good power saving effect. 5. [Cooling] 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 Applied] 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: <95% RH Atmospheric Pressure: 86KPa-100KPa Function: 1.
