Introduction: AC Arc Welder FAIL
I had the idea to make an arc welder from Tim Anderson's instructable "Build a Microwave Transformer Homemade Stick/Arc Welder". On his instructable he shows how to make a welder out of two microwave transformers.
I began working on it. After many hour of work and $80 spent it was finally finished. However, when I tried welding with it, it would not even arc. After half an hour of failed attempts I accidentally got my welding rod stuck to the metal I was welding. Before I even had a chance to remove it, one of the transformers began melting down.
What did I do wrong? Should I have used larger than 10 gauge wire for the new secondary coil? Should I have wound it more times? Fewer times? Do I have my transformers wired wrong?
If you can answer any of my questions please comment below. It would be greatly appreciated.
