220V 1PH, with flexible coil station, specially designed for heating and welding small metal parts and blades, ultra fast (Item# IHG06A3)


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 can not heat efficiently, like aluminum and metal powders. And uniquely they can heat parts from a distance. These heaters are the ideal tools for fine steel wires (such as those used in dentistry) annealing, small precision shaft quenching, hard alloy saw blade brazing and metal powders melting.

IHG06A3 Induction Heater Features

  • Separated heater on a cable so it can be used by hand like a wand for added heating flexibility.
  • Specially designed for heating and welding thin metal parts, blades and melting of small quantity of metallic powder, ultra fast.
  • Light weight (only 45 Lb), portable (with built-in handle), instant heat and up to 90% energy savings
  • Ease of use: just plug in the power and connect the water cooling system, our simple instruction allows you to use the heater in 15 minutes.
  • Precise control with digital output, frequency and current displays.
  • Remote foot switch for safer operation.
  • Dual automatic and manual modes.
  • Optional graphite and silica crucibles available. (melting material decides crucible type, weight and size of the material decide crucible size)
  • ISO 9001:2008 registered manufacturer.
  • We provide sample testing and custom made coils in our New Jersey facility

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 heat radiator temperature is over 55°C, 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 turned on and buzzer sounds 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 malfunctions
    • Induction coils touching each other
    • Input voltage is too low
  • Low water pressure protection: if water pressure goes below 29 PSI, machine will shut down, water protection light will turn on and buzzer will sound continuously.


  • 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 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 45°C.
  • Machine must be grounded properly all the time during operation.
  • Thread tape (or related material) is absolutely prohibited during installation of induction coils.
