Note: This model only available in 220 volt single phase.

IHG series 100 kHz to 1100 kHz high frequency induction heaters are among the latest products developed by Across International. They can quickly heat most metals that other frequencies cannot heat efficiently, like aluminum and metal powders. They can also heat parts from a distance, making them ideal for fine steel wire annealing, small precision shaft quenching, hard alloy saw blade brazing, and metal powder melting.

Main Features

• Specially designed for heating and welding thin metal parts, blades, and melting small quantities of metallic materials with ultra-fast response.
• Easy to use: just plug in power and connect the water-cooling system.
• Precise control with digital output, frequency, and current displays.
• Remote foot switch for safer operation.
• Dual automatic and manual modes.
• Optional graphite, MgO, and SiO2 crucibles available depending on the material and batch size.
• Frequency is non-adjustable and depends on coil design.
• ISO 9001:2008 registered manufacturer.
• Across International provides sample testing and custom-made coils in its New Jersey facility.

Safety Features

• Overvoltage protection: machine shuts down when input voltage is over 245V and resets automatically when voltage returns to normal.
• Overheat protection: if the IGBT heat sink temperature exceeds 55C, the machine shuts down until cooling conditions improve.
• Overcurrent and malfunction protections: machine shuts down if components overheat, interfering signals are detected, work pieces short against induction coils, machine failure occurs, coils touch each other, input voltage is too low, or water pressure drops below 29 PSI.

Important

• Always wear protective gear and goggles when operating the machine.
• Crucibles must remain covered during operation.
• Do not run no-load operation for long periods.
• Circulating water must be pure, clean, and below 45C.
• The machine must be properly grounded at all times.
• Thread tape or similar material must not be used during induction-coil installation.

Main Induction Furnace Specifications and Melting Capacity

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