That looks like you could make one of those out of the element in a hot water heater.Do you believe you can?

I was thinking of doing the same thing and spoke to a friend who has a big one. He said the consumables are expensive, something about nozzle, and it worked better on thin material than thick. He indicated a gas torch was better for heavy junk. So I never got one. I think they need really dry air also.
Lets see what everyone else says.

Are there any downsides to it? Noise, Smoke, anything else.. I have seen plans on the internet to make one. They used to be around for sale, but seem to have gone away. Why did people stop using them? Gas is expensive, electricity is pretty cheap.

...Well, it's kind of like touching two bare wires together, it just makes a big spark and heats up the metal into a liquified glob and it melts away. Kind of a Frankenstein looking thing. Like I said, not very precise, but it will separate two pieces of metal if you're brave enough to stand there holding it.
I think it would be better used for heating metal to bend or heating nuts to loosen them. As described in a previous post, I guess you just touch the carbons to the metal then turn on the welder to start the heating process.
It definitely won't take the place of an acetylene torch or a plasma cutter.
