    Assembly Instructions

    ​Obtain large Warren made transformer, variac, suicide cables, a 3/8" steel rod, and bowl of water. Connect transformer to the variac and ensure that it is off. Carefully install the suicide cables into the variac and then the wall. With everything off, install the 3/8" steel rod into the casted copper clamps. Ensure that correct placement is used. The casted copper clamps should be over the edge of the bench or cart and directly above a large bowl of water to capture the molten drop of steel.
