I see lots of Chinese made induction heaters on eBay and I get ads in my email from China fairly often for induction heaters. They all look like the same product made in the same factory (no surprise) and come in various power levels. They are advertised as being able to melt metals and heat treat parts. Induction heaters are nothing new but all the ones I see are now inverter based solid state devices, so I guess that's fairly new compared to the first one I ever saw 44 years ago that was made from an AM radio transmitter. I know they have been making pretty cheap induction stove tops for a while now too. But why in the last couple of years am I seeing so many being sold by so many different sellers? What am I missing? How many people need to melt small quantities of metals? Or need to heat treat small tools? Eric
