Make this DIY Spot Welding Machine using MOT and IC 555

Last Updated on June 6, 2026 by Swagatam Leave a Comment

Building a spot welding machine at home, it does not really need those complex SMPS circuits or costly stuff, nope. Instead a much simpler way is there, which people use, and it works quite well. We can use a microwave oven transformer, that MOT, and then add a small timing circuit with it, so now […]
