A long time ago I used an AC arc welder to melt 50 grams of steel to turn it into cast iron. It worked but I quickly realized that melting larger amounts would prove to be very difficult and never tried that experiment again.

The guy made a video for clicks. Cool. he showed an experiment that wasn't successful. Cool. Channels I don't like I don't watch.

There are plenty of DIY induction heaters.

That video you posted is a really good one compared the many others that are on youtube. I like the part where he uses a ocilliscope to confirm that the power factor is close to 1. Many on youtube add caps to improve the power factor on the work coil but does it really work if you don't have an ocilliscope?
