They sell the generator - its up to you to make the work coil and size the crucible, etc. - other than the one crucible and work coil it comes with which of course is a fixed size.
So it's not about the size, but the energy required to melt that amount of metal? It seems odd, then, that the same rig that will melt 30 kg of copper will only melt 10 kg of aluminum, which is a lot easier to melt. Or am I missing something?
