Hello everybody! Today I have a old welding machine . It has a lot of copper and aluminum in it . I separated the metals and melted the copper and aluminum . The result was a large copper ingot - 6.15 kg. and a small aluminum ingot -0.8 kg . This is my biggest copper ingot. I sanded and polished it.
