WARNING: Burning galvanized metal may release toxic Zinc Oxide fumes.
This project is extremely dangerous and should not be attempted without
adult supervision and adequate training. Misuse, or careless use, of
tools or projects may result in severe electric shock, cardiac arrest,
serious injury, permanent damage to equipment and property, and/or
death. Use of this video content is at your own risk.
By
modifying the secondary coil on a MOT, the transformer is converted from
a high voltage/low current device into a low voltage/high current metal
melter. The first MOT in the video produces just over 500 amps, and
the second one is capable of nearly 800 amps.
Any metal that
can conduct such low voltage electricity acts as a resistor between the
electrode wires, and heats up due to the extreme electrical friction.

@Shade I think he knows more than that... How is he going to kill himself with 2 or 3 volts?

@donreid nope, but with 500 amps, yes

@Ghost Guess what? Your car battery can produce even more than 500 amps, and at an even higher voltage of 12 volts. So the wattage (power) a car battery can produce (at least for several seconds) is 6 times more than his transformer. Yet you can grab hold of both terminals and hold them all day long, even with wet hands, without anything happening.

@Ghost Yes but at that low of a voltage it can't carry the current fast enough to do any damage

Its not the voltage that kills you, its the amps/current.

@Brutusbruno
But the voltage determines how much current will flow in accordance with ohms law... V = I.R

It shouldn't take any more energy than a regular microwave, which wouldn't affect the electricity bill too much.

You should be. Electricity is nothing to fuck around with. This guy knows what he's doing. Still, I would never touch live leads with my bare hands, no matter how low the voltage is.

@pauliec17 Microwave Oven Transformer. They get dead MOs and get the transformer out, cut the high voltage winding off it and replace it with a few turns of very big wire = 3 Volts at 300 Amps or more.

@Triode Makes me wonder if you're basically dead shorting the output how it is you're not flipping a circuit breaker somewhere up the chain.

@Saros if the secondary is supplying 3 Volts at 300 Amps then that is 900 Watts (really 900 VA) which is about what the transformer was supplying previously, but prior it was 4 kV at 250 mA (still 900 VA). Most of the people who convert those transformers don't fuse them or otherwise protect them and end up destroying them.
Also, when in use as a spot welder, they are only drawing large currents for 0.5 seconds and are welding thin sheets of metal together. It is a very cheap spot welder at ab More..

@Triode What limits the current on a dead short? Wire resistance?
Posted Nov-25-2012 BySaros (798.30) 
Saros View Channel Send Message

@Saros There's hardly any wire resistance, just a few milliohms, but it is AC so the limiting factors are the impedances (Z) from the primary and secondary coils' inductances. Even so this is extremely small for the secondary (it is just 3 turns) while the primary will have a few millihenry's of inductance and therefore some impedance (imp. is like resistance but for AC). You saw in the vid the narrator cook the secondary winding, well the primary would have burned too, but the insulation on it More..
