Microwave-oven-transformer-spot-welder, the welder uses a microwave oven transformer with the secondary cut off and rewound with 4.5 turns of 5 layers of 0.5mm copper strip, mounted on a plywood base-board. the ply i used is an inch thick, but that's just what i happened to have.. The power part of this spot welder is classical. it implements an mot microwave oven transfomer) with a 2 turn secondary winding made of heavy gauge wire. the current is fed to 2 bars made of 15 x 15 mm square brass tubes. the electrodes are made of machinned heavy gauge copper bus bar., building a spot welding machine from a microwave oven transformer: in this project i am making a diy spot welding machine to be used for building battery packs with 18650 lithium ion cells. i also have a professional spot welder, model sunkko 737g which is around $100 but i can happily say that my diy spot welder....

Recently i followed an instructables on building my own mot spot welder, and the build went great. i am getting power from a normal home outlet, which is 120v and 15a, and i am getting out around 2 volts, so around 900a for the output of my second winding. i used a large gauged stranded wire for..., diy spot welder from microwave - now with oled display!: this project is an outline of how to build a resistance spot welder using salvaged parts from an old microwave. im using it to weld nickel tabs onto 18650 battery cells but depending on how you position the arms it can be used to weld sheet metal ....

Have taken the oven apart. from the construction of the turbo jet engine to the flight - just one step - duration: 1:03:07. Игорь Негода recommended for you, do not try this at home. this video is just for entertainment and educational purposes only .i just made the video because i'm building one of those homemade spot welders from microwave oven ....

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. if you liked the metal melter you saw in my previous project, here's how you can make your own!
