    A friend just sent me the link to amuse me. I don't know why this was built or what its planned use was.
    http://akroncanton.en.craigslist.org/ele/3774925700.html

    6' high, weighs about 200-250 lbs. It runs off of 125V AC at 30 amps (requires its own breaker) and is powered by 6 neon sign transformers with a combined constant current of 210 milliamp output at the primary.

    I hope nobody kills themselves with it.

    Yup, looks like someone just wanted to have some fun and build a tesla coil. I have one about as tall but only 4" in diameter sitting in my basement, as well as a variety of smaller ones I built. I'm still working on the 4" one.

    It's just fun to make lightning in your basement or garage :D

    Is it really possible to be pulling 30 Amps at 125 AC and how safe is that ????

    Yes it's possible. It's more likely to have 30 amps at 230 V.

    Lol I reason I asked because I am a 6th generation welder and one of my machines runs at 120v at 20 amps which requires a big cord by itself whic I don't see anywhere in those pics...I noticed that all 120v machines run at 20 amps and was just figured that If I could more output with 30 amps 120v AC??

    Most houses have 230 V available since that is what is fed into the breaker box. Most circuit breakers connects one live wire to ground and gives 115 V. If you connect the circuit breaker to both live wires (requires a wide circuit breaker), you get 230 V. The current is limited by the amount the circuit breaker can handle before tripping.

    I know what it is and I knew what they were used for. The unknown is, why would someone want to make one today that requires 3.6kW of input power.

    I am really intersted to see if we eventually see a post something like this on AAC in the next few weeks...
