Introduction
The U.S. Solid 15 kW Medium Frequency Induction Heater operates at a lower frequency range of 1–20 kHz, delivering exceptional deep heating penetration. This lower frequency not only heats the surface but also allows electromagnetic energy to reach the core of the workpiece, ensuring uniform and thorough heating. Ideal for thick, dense, or heavy metal components, it excels in deep hardening, forging, shrink fitting, and preheating applications. With adjustable input current from 1–32A and a main unit paired with a compact extension unit, it provides efficient cooling, precise temperature control, and reliable performance—perfect for industrial processes where high-frequency heaters cannot achieve sufficient core penetration.

FAQ
Problem 1: When the over-temperature light comes on, what should be done?
Let the machine cool down for a certain period and then restart it. Before water enters the machine, ensure that its temperature is below 40°C (104°F). Use only cool and clean water at all times.
Problem 2: How to handle the situation when the over-voltage light comes on?
Ensure that the machine is connected to the voltage suitable for its model as per the specifications. Check that the power supply matches the required 380V or 480V three-phase input.
Problem 3: How to troubleshoot if the machine fails to power on?
Check the circuit breaker, fuse, power connections, and the power status of the outlet. Make sure all connections are secure and operating properly.
Problem 4: How to deal with the machine beeping during startup?
Inspect the connection between the coil and the machine to ensure proper installation. Ensure that the coil is positioned correctly, without excessive turns or improper coverage.
Precautions
- Always ensure proper grounding of the machine to prevent electrical hazards.
- Maintain a clean and debris-free environment around the machine to ensure proper ventilation.
- Position the heater on a stable and level surface to ensure safe operation.
- Utilize original manufacturer parts for optimal safety and performance.
- Ensure cooling water temperature is below 40℃ before operation to prevent overheating.
- Use only clean, cool water for the cooling system. Replace water regularly to maintain efficiency.
- The machine generates heat during operation. Avoid direct contact with your hands.
- Before maintenance, always disconnect the power supply and wait for the machine to cool down.
