Abstract: Disclosed herein are embodiments of an oxygen torch cutting system. In one embodiment, the oxygen torch cutting system comprises a cutting torch supplied with an oxygen gas source, a fuel gas source, and a third gas source. The third gas source can be a mixture of hydrogen and oxygen gasses (HHO) or hydrogen gas (H2) and can be added to the fuel gas source. The oxygen torch cutting system can include one or more gas lines, gas control valves, and flashback arrestors. The addition of HHO or H2 gas to the fuel gas source can be facilitated by a tee connector. The inclusion of HHO or H2 gas into the fuel gas source increases the efficiency of the oxygen cutting torch system by replacing a significant amount of the fuel with less expensive HHO or H2 gas and increases the oxidation rate of metal and creates a cleaner flame.
