1. What is the JL-25 High Frequency Induction Heating Machine used for?

The JL-25 is designed for induction heating tasks such as brazing, melting, quenching and annealing of conductive materials in industrial and workshop environments.

2. What is the operating frequency range of the JL-25?

The machine operates in the 30–100 kHz frequency range, allowing adjustment for different heating depths and applications.

3. What are the cooling requirements for the JL-25?

The JL-25 requires a water cooling supply with pressure greater than 0.2 MPa and a flow rate of approximately 2–5 L/min.

4. How heavy is the JL-25 and is it portable?

The unit weighs 28 kg. It is relatively compact for an induction heater and can be moved by one or two people, but it is not a handheld device.

5. What warranty and after-sales service are provided?

6. Which certifications does the JL-25 have?

The machine is certified with ISO9001:2008 and carries CE and BV certifications.

7. What are the core components of the JL-25?

Key internal components include a PLC, motor and gear assemblies.

8. What materials can be heated with this induction machine?

Induction heating works best on electrically conductive materials — primarily ferrous and many non-ferrous metals. Specific heating parameters depend on the material's conductivity and geometry.

9. Is the JL-25 easy to set up and operate?

Yes — the machine is designed for quick setup and user-friendly operation. Always follow the supplied operating instructions for correct electrical, cooling and coil connections before use.

10. How do I choose the right frequency and power settings?

Selection depends on the material type and desired heating depth: higher frequencies concentrate heat near the surface, while lower frequencies penetrate deeper. Start with conservative settings and run test pieces to optimize parameters for your application.

11. What safety precautions should I take when using the JL-25?

Use appropriate PPE (gloves, eye protection), ensure proper grounding and ventilation, keep flammable materials away, check cooling and electrical connections, and follow the manufacturer's safety instructions.

12. What routine maintenance does the JL-25 require?

Regularly inspect and clean cooling lines, check water quality and flow rate, verify cable and coil condition, keep vents clear of dust, and follow the manufacturer's maintenance schedule to ensure reliable operation.

Spare parts for core components (PLC, motor, gear) and accessory items are typically available from the supplier. For replacement or custom coils, contact the vendor to confirm availability and compatibility.

14. Does the JL-25 include documentation or quality proof?

Yes — the product includes a machinery test report and the supplier provides a video outgoing inspection for additional quality assurance.

15. Can the JL-25 be used for controlled quenching and annealing processes?

Yes — the JL-25 is suitable for heating stages in quenching and annealing. Achieving consistent metallurgical results requires correct temperature control, timing and quench media; perform process validation for your specific materials.
