Abstract
An exothermic cutting rod that comprises a tube and a plurality of wires. The wires may be cored wires that comprise various mixtures of powdered metals and other additives. The cored wires may be disposed within the inner circumference of the tube. The wires filled with powdered metals may allow the manufacturer to more quickly adjust the mixture ratios and develop a combination that has better performance characteristics, such as a reduced requirement of pure or substantially pure oxygen, or compressed gas.
