摘要： 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.

摘要： A cutting torch system comprises a cutting torch and a control system. The cutting torch includes a cutting oxygen channel for supplying cutting oxygen, a heating oxygen channel for supplying heating oxygen, a fuel gas channel for supplying fuel gas, an ignition mixer configured to selectively generate ignition gas from the heating oxygen and the fuel gas, and at least one sensor adapted for measuring a pressure and/or flow rate in one of the channels. The control system is adapted to maintain a temperature of the cutting torch to allow operation of the at least one sensor by adjusting a flow rate and/or a pressure of the gasses supplied to the cutting torch and/or by switching the cutting torch between an ignition mode and a cleaning and cooling mode.

摘要： A swivel head assembly for a dual head oxy-fuel torch which incorporates a fixed oxygen delivery head and a 360 degree rotatable fuel delivery head mounted coaxially upon the oxygen delivery head, such that regardless of whether the torch is pushed forward, drawn backward or manipulated to either side, the fuel delivery head can be readily repositioned relative to the oxygen delivery head so as to always lead the delivery of oxygen for preheating, thus accommodating ease of arm movement and avoiding the need for cumbersome body movement and positioning around the target cutting surface.

摘要： A method of starting an auto-ignition gas torch includes increasing a flow of oxygen above zero and increasing a flow of fuel gas to a level lower than the flow of oxygen for improved start reliability. In one form, the flow of oxygen is from about two times to about six times higher than the flow of fuel gas.

摘要： A fuel gas and oxygen mixer for a gas torch comprises a tubular body having a mixing passage extending therethrough and having an upstream end connected to sources of a fuel gas and oxygen and a downstream end for delivering a mixture of the fuel gas and oxygen to a torch tip. The fuel gas is axially supplied to the upstream end of the mixer, and the oxygen flows along the outer surface of the body in the upstream direction from a point adjacent the downstream end of the body and then into the mixing passage through radial ports adjacent to the upstream end of the body. The counter flow of oxygen is through a passageway which provides for cooling of the mixer during normal operation of the torch and for the quenching of reversely flowing hot gases during a back fire.

摘要： Disclosed is a cutting torch having a preheat tube in which the mixing structure within the preheat tube includes both a heat absorbing spiral and a blunt-nosed jet in the oxygen passageway upstream of the injection point at which the fuel is mixed with oxygen. The jet is simple to machine during the manufacturing of the torch parts and, when properly positioned, causes sufficient turbulence in oxygen flow to assure complete and consistent mixing of the oxygen with the fuel, even at low fuel pressures. The actual mixing of the fuel with the oxygen is accomplished at a point immediately downstream of the jet where a plurality of transverse passageways leading from a fuel carrying channel intersect the central passageway leading from the jet. These transverse passageways are preferably disposed at an acute angle to the longitudinal axis of the mixer tube such that the transverse passageways are pointed downstream and inwardly toward the center of the mixer tube.
