Attempting to repair or modify a transformer can be dangerous. I included screenshots of the search results for ‘microwave’ on craigslist and another classified ad site. Perfect for those other DIY projects you have that call for AC power. As I don't have a large power supply so I used six 6v sealed lead acid batteries all in series to gain 36v to power my ZVS driver. . Other projects using MOT’s typically rip out the high voltage secondary windings and re-wind them as low voltage, high Feb 19, 2023 · Microwave oven transformer at high frequencies? Power Electronics: 9: Jul 6, 2024: C: How does a MOT (microwave oven transformer) work: Power Electronics: 10: Aug 15, 2023: T: microwave oven transformer rewind: Power Electronics: 4: Jul 9, 2023: S: Need transformer for microwave oven: General Electronics Chat: 7: Oct 7, 2021: M: MOT Questions This project aims to repurpose a microwave oven transformer into a spot welding machine. To start your project, you will need to extract the microwave transformer from an old microwave. Locate the transformer: It is typically a large, heavy object inside the May 3, 2022 · The High Voltage is supplied by an unmodified Microwave Oven Transformer. Microwave oven transformers. The transformer core measures 1. T. Sep 21, 2014 · Nice hack, Philpem made one a while back but his version used a 600K uF (0. All you'd need to do is wind the new secondary through the holes in the core. Dec 13, 2012 · In this project, 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, which is enough amperage to melt metal. At the center of this project lies the microwave oven transformer. Sep 27, 2012 · With the microwave oven transformer (M. The process involves careful handling of high-voltage Dec 10, 2011 · I noticed a microwave oven transformer has exposed windings it is easy to see there are 6 layers, 10 turns on each of the first 5 layers and 7 turns on the top layer making a total of 57 turns on the primary coil. It only takes two or three turns of welding cable. ) salvaged in a previous project, a simple electrical circuit can be rigged to get high voltage arcs to fly outward and upward along a "V" shaped spark gap. A typical output voltage is 2kVeff, at around 1000W power.
