Across International IH series mid-frequency induction heaters are designed to operate between 30 and 80 kHz. Mid-frequency heaters are excellent for small parts heating, cutting, diamond tool brazing, soldering copper plumbing fittings, auto parts heat-treating, annealing of stainless steel containers and more.

Mid-frequency induction heaters are the simplest in terms of design and implementation. With their low cost of ownership and maintenance, they are among the most popular and reliable machines for industrial heating applications.

Safety Features

• Overvoltage protection: machine shuts down when input voltage is over 245V. Overvoltage light turns on and the buzzer sounds continuously until voltage goes below 245V.
• Overheat protection: if the sensor detects IGBT heat sink temperature over 55C, the machine shuts down and alarms until cooling conditions improve.
• Overcurrent/malfunction protections: machine shuts down if there is overheating, interfering signal detection, short circuit between work pieces and coils, machine failure, coils touching each other, low input voltage, or low water pressure below 29 PSI.

IMPORTANT!!

• 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.

Main Induction Furnace Specifications and melting Capacity:

The table below outlines the maximum melting capacity for each induction furnace model. Please note that each melting cycle takes approximately 50-60 minutes for a cold furnace and 20-30 minutes for a hot furnace.
