It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof (see figure). The shell diameter of a 10-, 100-, and 300-ton EAF is 1. As always, you'll want to gather up the materials and tools for the job. You will need everything listed below. Some of the materials can be sub2. The first and hardest part of the project is the actual arc welder component of the EAF. Be prepared to fully use clamps, vice clamps, and a bit3. This part is what gives the transformer a bit more "oomf" to it. Also, it allows us to hook it up to our leads to create an arc.After cleaning o4. Now we'll start to build the leads that will strike the high current arc used to melt metal. In our case, we can also use our battery parts as t5. This is easily the well, the easiest part of the project. Just make sure to wear safety goggles and a mask for this, to prevent inhalation o6. The total time required to build the EAF was a little time consuming, based on how we built it and the materials we used. Transformers vary in s7. To improve this project, we should have realized that the dimensions of transformers and the amount of wire needed also varies. Our secondary ..
