I’ve just modified this microwave oven
transformer into a dangerous little
device 800 amps of electrical current is
about to be really bad news for anything
made of metal
[Music]
today I’m in the mood to melt some metal
this microwave oven transformer used to
be a dangerously high voltage device but
I modified it so the voltage is
extremely low and it’s the amps now that
are insanely high high enough that when
the electrodes touch this screw it melts
into a little ball of steel this time
I’ve hooked it up to a machine screw for
melting and when it heats up it changes
color and the outer layer bursts into
flames if I hold the electrodes in
constant contact you can see molten
metal flowing down the screw and within
seconds it’s completely gone I just love
the way these light up and flash
throwing off sparks as they melt this
bolt is longer so it’s taking more time
to melt you can see an array of color
changes as the metal heats up to the
point where it begins to glow a burning
bright orange back on my workbench you
can see the input voltage to the primary
coil is about 120 volts AC which is
typical mains power in my area and with
this modified secondary you can see I’ve
stepped the potential down to only three
volts the voltage is so low that I can
actually touch the live wires with bare
hands and not feel anything even though
the power being generated is enough to
completely incinerate this would screw
on contact this much power has the
potential to kill you so don’t ever try
this yourself now here’s a 5/16 inch
bolt I’m trying to melt and it’s
building up so much heat that my 4 gauge
electrode wires are smoking as it’s
cooling I’ll try a little amateur
blacksmithing while I have the chance
because this got so hot I just melted my
melter 4 gauge wires just aren’t enough
to handle the extreme current pumping
through these wires that’s ok though
because the primary coil is still good
so I’ll just rip off the secondary so I
can use the rest of this in another
project like making a makeshift stick
welder look for that in a future video
in the meantime I still have this other
MOT that was salvaged from a microwave
in a previous project and after making
the proper modifications I’ve got a new
metal melter sporting this thicker 2
gauge wire to fire it up I’ll attach
input wires to the primary coil plug
those into a power bar and flip on the
switch you can see the low-voltage
sparks off the terminals and I’m
measuring their potential at just over 2
volts
once again for your entertainment I’m
holding the leads barehanded and you can
clearly see there’s power to the system
because of the electrical arcing there’s
also a visible amount of current pump
the thicker wires should be able to
handle higher temperatures than the
first so I’m going to experiment on
various items around the house like this
iron nail and a drywall screw how about
some lead solder or a zinc washer and
various other objects made of metal one
friend suggested I try melting a padlock
and that seemed like a fun idea it’s at
full power and the steel retaining clip
is getting extremely hot but the metal
isn’t melting something inside the
casing just caught fire though and
although the retaining clip isn’t
melting the lock is so hot that the clip
just fell open along with the rest of it
I’ll try a couple of amateur spot welds
on some stainless steel and I’m
impressed at how much effort it takes to
get them to break when experimenting
with an aluminum can the electrodes cut
through the metal like butter but this
thicker aluminum disc won’t glow at all
I’m not sure how hot it is but when I
drip water on it the water is instantly
boiled and vaporized I did get this
steel coin pretty hot and if it’ll do
that I’m wondering what it will do to
steel wool amazingly nothing happens
unless the electrodes are so close
they’re almost touching aluminum foil
will be very exciting either but I’ve
managed to reduce this sheet down to a
little blob of metal I’ve got some
neodymium magnets ready but the voltage
is too low to get through all eight
however if I tap onto two it seems to be
working really well they’re getting so
hot they’ve gone totally incandescent
and apparently have just been liquefied
these are among the world’s strongest
magnets but after exposure to
temperatures over 300 degrees Celsius
they lose most of their magnetic
properties here’s a large steel nut
that’s harder to heat but in the end it
glows very nicely as well this one’s
just got so hot that it’s exploding
liquid metal as expected I got no
visible reactions from a 250 volt light
bulb or this audio transformer but I did
have a lot of fun melting down the tines
on this fork this brings back memories
of curling plastic forks over the fire
as a kid it’s not very useful anymore
but it looks pretty neat I’m applying a
current to the underside of this knife
and can visibly see the point of contact
the whole blade is glowing and this is
looking really cool at this point the
blade is really easy to bend for my last
trick
I got a circuit board with some
high-temperature solder that my
desoldering iron wouldn’t melt but
hooking a couple of nails to the
electrodes gives me the ability to
instantly liquefy the solder on these
well we cheated death again and
destroyed a lot of metal doing it if you
