Build a Microwave Transformer Homemade Stick/Arc WelderIt just gets better from there.
I had no idea making a DIY welder would be so easy to do. And, it's pretty much FREE!
So here's what you need to build a welder:
- Two beat up old microwaves
- Some 10 gauge wire
- Wire nuts
People throw out microwaves all the time, if you keep your eyes on the curbs.
Or, you can get microwaves at the local thrift store for $10 each.
