    Abstract: An improved exothermic cutting system is presented mounted upon a standard Alice pack frame reduced by three inches for additional comfort and safety to the wearer. A lightweight aluminum plate is welded to the Alice pack for stability while serving as a rigid platform upon which the cylinders, manifold, battery ignition and rod compartment is secured. The backpack design provides oxygen via an oxygen hose to the cutting torch. The design also provides a dual extruded electrical cable connected to a 12 volt battery at one end, and an igniter head at the other end, necessary to initiate the exothermic reaction. Overall, the improved backpack system allows for greater comfort and convenience. The improves system also protects the components from damage during deployment.
