Feature: 1. High Efficiency: Induction heating tools use an electromagnetic field to heat metal, which is faster, more accurate and more efficient than oxyacetylene systems. No open flame caused by heating, ensuring your work environment is safe. 2. Highly Illuminated Work Area (LED): The induction heater removes the built in LED light at the end, providing work area illumination even when working in the dark. You can understand the progress of work more clearly and know the status of the object being heated. 3. Toolbox And 8 Coils: The magnetic induction heater set comes with its own toolbox, which is sturdy, durable and cool to look at. You can carry it with you anytime when you are working outside, while keeping your workshop neat and organized. The kit comes with 8 different sizes of coils, 8 pieces of coils including: 2 pieces dia 0.79inch (20mm), 2 pieces dia 0.98inch (25mm), 2 pieces dia1.18inch (30mm), 2 pieces 29.53inch (750mm) length free coils, multiple coil types and sizes can be adapted to your work in many ways to make your workflow smoother. 4. 3.0mm Copper Core: The induction coil set is composed of 3.0mm brass core brass wire, which is more reliable than the 2.5mm brass core coil on the market and can be heated up to 800?? for a long time without fear of high temperature test. 5. Cooling System: The automotive flameless heating tool is equipped with a cooling fan and overheat protection to heat up the unit without damaging nearby heat sensitive components, extending the life of the unit. Enhanced heat stabilized thermoplastic housing improves internal and external durability. 6. Wide Application: 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, various small metal parts such as gears, pulleys, bearings, etc. Specification: Item Type: Magnetic Induction Heater Kit Material: ABS, Brass Model: FH 1500 Power Saving Effect: Power saving up to 30% or more Operating Frequency: 50-60Hz Rated Power: 1500W Heating Temperature: Approx. 800??/1472?H Heating 800 ??
