How to Make The Metal Melter

In a previous video I used a modified Microwave Oven Transformer as an electrical metal melter. In this video you’ll learn step by step how it was made, and what I’m using it for now. In a previous project, I found an old microwave in a dumpster and hacked it open to see what components […]

HOW to make an arc welding machine using the toroidal transformer of an amplifier, Power core

Hello all of you. Today I go back to the topic of power supplies for amplifiers and electric arc welding machines. That is the power supply for the high power amplifier that I made in the previous video. Use toroidal transformer to make arc welding machine. It is a toroidal transformer. I removed this toroidal […]

The Scariac (Poor Mans Variable Power Controller)

Mixing water with electricity is typically discouraged, and for good reason, but in this project we’re pumping electricity into water, and a bit of drain cleaner to create a poor mans power controller. You might have heard of a Variac. This is the Scariac. In a couple of other projects, we fashioned a homemade stick […]

Make a Spot Welder for Cheap!!

A typical resistance spot welder like this can range in price from around $200 to over $800! That’s a little out of my price range, so for this project let’s make this one from common materials, and for just a few bucks! This modified transformer is the heart of the Spot Welder, and you might […]

Easiest MOT Salvage Tutorial Pt.2

Welcome to Part 2 of my tutorial series on MOT salvaging, where I show you how easy it is to turn a broken microwave into some cool projects. If you’ve just stumbled across this video, go watch part one first, it explains how to get a microwave oven transformer and tear it down the easiest […]

Why Use AC Instead of DC at Home??

Hi. Why do we ever use AC to power homes instead of DC? Haven’t I showed you that AC is typically more dangerous than DC? [Painful Gurgle] Can we run everything on DC? Yes! In fact pretty much every device at home has to rectify AC into DC first before it can use it so […]

Making an ARC Welder – Part 2 of 2

In part 1 of this project, we scavenged some parts from household appliances, and modified them so we could weld metal. In this project, we’ll be rigging up the electrical system, and adding some finishing touches so that our homemade stick welder is ready for operation. I started this project with a scrap piece of […]

Tiny & compact spot welder

it’s a special electrical wood from electrical cabinet It’s a micro wave transformer? Yes it is do you see the wire I remake? 25² copper nice I am going to put a dimmer on it Do you see, on transformer you need to put capacitors on in or out? on the primary coil of the […]

Homemade Stick Welder – From Microwave Parts!

I found this microwave in my neighbors garbage can. So I took it home, and turned into an AC stick welder. In this project, we’ll be testing out this contraption to see if it actually works. Because if it does, we’ll have the metal welding power to make a puzzle for entertaining guests, or build […]

What is a Transformer? An Electrical Transformer Tutorial

In this video I am going to explain how transformers work and show you how to wire one up to step mains voltages down to lower voltages that your projects may need. In my project we will step down 120V to 24V but the same principles will apply to most transformers. I’ll also give you […]
