4. Setup
4.1 Unpacking
- Carefully remove all components from the carrying case.
- Inspect the induction heater unit, coils, and power cord for any signs of damage. Do not use if damaged.
- Ensure all listed components are present.
4.2 Coil Installation
- Select the appropriate induction coil for your specific task. Choose a coil that can fit snugly around the metal part to be heated.
- Insert the ends of the chosen coil into the two terminals on the front of the induction heater unit.
- Tighten the retaining knobs on each terminal to secure the coil firmly in place. Ensure a good electrical connection.
- Verify that the coil is properly seated and stable before proceeding.
5. Operating Instructions
5.1 Basic Operation
- Ensure the selected coil is securely installed and the work area is clear and well-ventilated.
- Plug the power cord into a compatible 110V AC outlet.
- Position the induction coil around the metal component you wish to heat. Ensure the coil does not touch any non-metallic or sensitive parts that could be damaged by heat.
- Press and hold the power button on the handle. The LED indicator will illuminate, and the heating process will begin.
- Observe the metal part as it heats. Release the power button once the desired temperature is reached or the part begins to loosen.
- Allow the heated component to cool sufficiently or use appropriate tools to handle it. The coil itself will also be hot; avoid direct contact.
- After use, unplug the device and allow it to cool completely before storing.
5.2 Applications

5.3 Principle of Flameless Induction Heating
Image 5: This diagram illustrates the principle of flameless induction heating. A high-frequency current passes through a copper coil, creating an alternating magnetic flux. This flux induces eddy currents within the metallic heating element, generating heat directly within the metal. This method is precise and does not require water cooling, unlike traditional sparking methods.
The VEVOR H7L uses electromagnetic induction. When high-frequency current flows through the induction coil, it creates a rapidly changing magnetic field. When a conductive metal object is placed within this field, eddy currents are induced in the metal. The resistance of the metal to these eddy currents causes it to heat up rapidly and precisely from within.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your induction heater.
- Cleaning: After each use, ensure the unit is unplugged and cool. Wipe the exterior with a clean, dry cloth. Do not use abrasive cleaners or solvents.
- Coil Inspection: Regularly inspect the induction coils for any signs of wear, damage, or fraying. Replace damaged coils immediately.
- Storage: Store the induction heater and coils in the provided carrying case in a dry, clean environment, away from direct sunlight and extreme temperatures.
- Ventilation Ports: Keep the cooling fan and ventilation ports free from dust and debris to ensure efficient heat dissipation.
