High amperage electricity can easily melt metal! In this video you’ll learn step by step how to modify a microwave oven transformer into a high-current device that can pump out 800 amps of electrical current. This is how to build The Metal Melter!

Project History & More Info:
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.
A practical application of this modified transformer is shown in another video on how to make a spot welder. This way, the high current can be directed to one focused location to fuse sheets of metal together on contact.
The Library’s John W. Kluge Center sponsored a symposium featuring scholars who were recently among the first to examine the papers of King George III, the English monarch in power when the American colonies declared independence, in the Georgian Papers at England’s Windsor Castle. The Library of Congress partnered with the Omohundro Institute of Early American History & Culture and King’s College London to host the symposium and support the study of the collection of King George III through the Georgian Papers Programme, a partnership among British and American institutions.
Speaker Biography: Arthur Burns is academic director of the Georgian Papers Programme and professor of modern British history at King’s College London.
Speaker Biography: Jim Ambuske is Farmer Postdoctoral Fellow in Digital Humanities at the University of Virginia School of Law Library.
Speaker Biography: Andrew O’Shaughnessy is vice president of Thomas Jefferson’s Monticello and professor of history at the University of Virginia.
Speaker Biography: Karin Wulf is director of the Omohundro Institute of Early American History & Culture and professor of history at the College of William & Mary. The Omohundro Institute and William & Mary are the primary U.S. partners in the Georgian Papers Programme.
