There are three major components to the system: the power supply, the compensating capacitor/transformer and the induction coil/smelting crucible. Our heaters automatically adjust to the best resonant frequency in order to achieve the most efficient overall heating results based on our customer’s requirements which include heat penetration, heating efficiency, operating noise and electromagnetic homogeneity. Two of our most popular low frequency machines are the Melting Furnaces with Tile-Pour Melter and Auto-feeding Rod Heating Furnaces for Forging.
Safety Features
- Overvoltage protection: machine shuts down when input voltage is over 245V. Overvoltage light will turn on and buzzer will sound continuously. Alarm and light shut off automatically when voltage goes below 245V.
- Overheat protection: if sensor detects IGBT heat sink temperature is over 55⁰C, machine will shut down, overheat light will turn on and buzzer will sound continuously. Increase water pressure or lower water temperature until alarm goes off itself.
- Overcurrent/malfunction protections: machine will shut down, indicator light will turn on and buzzer wil sound continuously if one of these situations occurs:
- One of the machine parts becomes overheated.
- Interfering signal detected.
- Short circuit between work pieces and induction coils
- Machine failures.
- Induction coils touching each other.
- The input voltage is too low.
- Low water pressure protection: if water pressure goes below 29 PSI.
CAUTION
- Always wear protective gear and goggles when operating the machine. Crucibles must be covered all the time during operation. Across International is not responsible for any injury or damage caused by misuse.
- Do not run no-load operation for a long period of time, it might cause damage to the machine.
- Circulating water must be pure, clean and below 45C.
- Machine must be grounded properly all the time during operation.
- Do NOT use single-turn coil if coil diameter is smaller than 4 inches, it will cause high frequency damage to the machine.
- Thread tape (or related material) is absolutely prohibited during installation of induction coils.
