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.

A cutting nozzle for a gas torch, such as a postmixed oxy-fuel gas torch, comprising a body with a torch end adapted to engage the gas torch, a discharge end, and a peripheral surface between the torch end and the discharge end. The body has a plurality of bores for respectively conducting fuel gas, preheat oxygen and cutting oxygen through the nozzle, each of the plurality of bores extending from the torch end and terminating in a respective discharge orifice at the discharge end of the body. A set of the plurality of bores are preheat oxygen bores connected to an oxygen source at the torch end for discharging the preheat oxygen at the discharge end. A plurality of air bores each have an inlet orifice located on the peripheral surface of the body and open to an air source, and a discharge orifice in or proximal to the discharge end.

An oxy-acetylene cutting torch tip cleaner includes an elongated body portion with at least one actuator and at least one associated housing bore for storing a cleaning pin. Each cleaning pin is coupled to an actuator movable from a first position with the cleaning pin contained in the housing bore to a second position with the cleaning pin extending from the housing bore, for abrading and cleaning the cutting torch tip. Each actuator, coupled to its cleaning pin with a slider, is biased to the first position and a lock engages each actuator in the second position such that when the lock is disengaged from the actuator at the second position with the cleaning tip extended from the body, the actuator automatically returns to the first position thereby retracting the cleaning pin back into the housing bore.

The invention relates to a nozzle (1) for cutting steel workpieces and workpieces made of iron alloys, comprising a nozzle body (2), wherein the nozzle body (2) has two cutting-oxygen bores (5, 5a), which extend from an inlet side (6) of the nozzle body (2) to an outlet side (8) of the nozzle body (2) in order to form two cutting jets (10, 10a). The double cutting flame cuts the steel more strongly in the so-called groove trail. The cut is thus more effective. This permits an increased cutting speed, which in turn causes a reduction in the heating-gas consumption.

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 (H.sub.2) 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 H.sub.2 gas to the fuel gas source can be facilitated by a tee connector. The inclusion of HHO or H.sub.2 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 H.sub.2 gas and increases the oxidation rate of metal and creates a cleaner flame.
