Where can I find high voltage electrical supplies?


Does anyone here know where I can get the supplies I need to make a
steel plate safely heat copper to 1984.32 F or maybe a little bit above
that? I have been reading up on electrical heaters and I want to make one
that utilizes a resister that can take up to 2000 to 2500 F and a step down transformer that I can use to plug this small kiln into my wall. I have
looked inside of radios and stuff and they usually look like a fifty square
pieces of sheet steel with A crap load of copper wire wound about it. I
mean is it possable to heat a steel plate to that temperature without melting the electric wire that connects all the parts? I see stoves with
iron that connects to resistors that can easially controll the temperature
of the iron but again I don't know where to find the supplies I need for
higher temperature electricity.

Also I was thinking about makeing a electric welder if anyone would care to shine some light on the subject here at the totally awesome DIY
electricity forum.

I actually have planned to test it outside already. I might just leave it an
outside machine but If I can syncronyze it to operational standards then I
will be a happy camper with melted copper on my desk top ready to mold.
I Think I might need both a step-down transformer and a step-up
transformer for this project but I wont be using it inside untill it works.

Also checking out that chat room, I just had some trouble loggin in for a second. Prolly server side update or something but I'm logged now.

I have no idea what you're talking about. I can't follow that post at all. And it's not because I'm unfamiliar with the subject matter. What are you trying to accomplish?

Well I guess I should be asking if there are resistors that can resist electricity that may be very hot. and I don't know where to buy a step down transformer (the type they put in household radios.

Majority of the Copper you see are alloy's, not pure Copper. Also beware, that the whole process also causes off gassing over time that can be harmful. Your best bet is to speak to local artists that do this stuff for a living, and see how they do it, or check the link above.

What? This still isn't making any sense. You should be explaining what you are trying to accomplish first. Are you trying to melt scrap copper? Are you trying to separate copper from other metals? What is the goal here?

Probably going to melt those zinc pennies down, or pulling copper out of stuff, and thinking that he could get around with making his own ingots and selling through other methods.

Yeah. If that's the plan, it's unlikely to be economical under any circumstances, and especially not using resistive electric heating. Resistive heating is never used for melting copper. It's simply not effective at those temperatures, for transferring that much heat to solid metal objects. Way too inefficient. Electrical melting of copper is done using induction heating of graphite or silicon carbide crucibles. Otherwise, a gas-fired furnace is the way to go. The need to maintain an inert or reducing atmosphere also makes electric heating a bit more complicated for copper.

He should probably just heat it to celcius temprature, that way he would only have to heat it to 1084 degrees.

What I want to know, is that has the OP realized how much amperage this home made smelting furnace will draw, for the size of the project.

OP is clueless about his whole project.

No need to build one, you can buy one
