Hi,
Is Arduino something I can use to make an induction heater? Any advice would be appreciated.
You may be able to use an Arduino to control an induction heater.
What do you want the Arduino to do? You need to give us a lot more information.

Hi,
Welcome to the forum.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom... 
If you buy an induction heater module, all you can really do to 'control' it is to turn the power on and off. You have to switch the OUTPUT side of the power supply or the oscillator may not start. You can do that with a relay if the contacts have sufficient current switching capability. Take the rated wattage of the heater and divide that by the power supply voltage. For example if you have a 120W oscillator with a 12V supply voltage you will need relay contacts that can handle the 10A 12V switching.
This design came as a result of a search for “Dynavap induction heater”:
There is no big role for an Arduino though.
I wonder if those devices operate at a frequency where they need FCC type acceptance certification?
