A tool for holding a torch having a fuel containing cylinder at one end and a flame directing nozzle at an opposite end. The tool has a base with first and second parts arranged in a cooperative stacked relationship relative to each other and defining a spherical socket therebetween. The second part of the base has an open top. A positioning receptacle is seated and rotatable within the spherical socket defined by the base. The receptacle has a spherical outer surface and a cylindrical blind cavity opening to the spherical outer surface of the receptacle so as to receive and releasably hold a lengthwise portion of the fuel containing cylinder therewithin. A manually operable, spring biased assembly is mounted in operable combination with first and second parts of the base and is operable in either a locked condition or an unlocked condition. In the locked condition, the spring biased assembly applies a first clamping force to the outer spherical surface of the receptacle to restrain the receptacle in a selected and adjusted position and against movement relative to the base and applies a reduced clamping force to the outer spherical surface of the receptacle when in an unlocked condition.

The invention relates to an ozone supply unit (26) for a flame burner apparatus and/or an oxygen cutting apparatus (10), comprising an oxygen inlet (28) to be supplied with oxygen (18), an ozone generator (32) coupled to the oxygen inlet (28) and configured to convert at least a part of the oxygen (18) supplied to the oxygen inlet (28) into ozone (18a), and an outlet (30) coupled to the ozone generator (32), wherein the outlet (30) provides at least a part of the oxygen (18) supplied to the oxygen inlet (28) and at least a part of the ozone (18a) converted by the ozone generator (32). The ozone supply unit (26) is configured to be integrated into a flame burner apparatus and/or an oxygen cutting apparatus (30). The invention further relates to a method for supplying ozone to a flame burner apparatus and/or an oxygen cutting apparatus (30).

A heat shrink gas gun has a handle which has a back side and a front side. The front side of the handle includes a cavity extending along an axis. An igniter is configured for ignition of the heat shrink gas gun and is actuated by a trigger. The igniter is insertably disposed in the cavity. The igniter is releasably received in the cavity. A trigger guard is positioned in front of the trigger and the front side in a spaced relationship. The trigger guard includes a through hole corresponding to the cavity so as to facilitate installation and replacement of the igniter.

The present invention concerns a joined connection and a joining method for welding torch components with a first metallic tubular segment and a second metallic tubular segment, which are joined to each other by plastic deformation via an interlocking connection. The problem which the invention proposes to solve is to indicate a joined connection as well as a joining method in which two metallic welding torch components can be joined without the use of thermal joining methods, yet with comparable quality. The problem is solved in that the interlocking is formed in at least two directions of the joining surface bordering one another.

A method for flame straightening is disclosed, wherein acetylene with oxygen is combusted by means of a burner to yield a flame, and the flame is directed onto a workpiece so as to heat the workpiece, wherein an electric field is applied between the burner and the non-melting workpiece which is electrically conductive, or the electric field is applied between the burner and a non-melting electrode arranged on the non-melting workpiece side to reduce NOx emission.

A flame gun with a flow control ring includes a body with a gas outlet assembly disposed therein. The gas outlet assembly includes a flow regulator being rotatable about an axis. A flow controller is coupled to and operably rotatable relative to the body. The flow controller is configured to drive the flow regulator rotationally and includes a connecting portion connected to the flow regulator. The flow controller includes an input portion disposed in a spaced relationship with the connecting portion and includes at least one link arm interconnecting and extending between the connecting portion and the input portion. The input portion is disposed circumferentially and surrounds at least half an outer periphery of the body.

A gas torch includes a base couplable to a gas source supplying gaseous fuel and gas ports formed in a top surface of the base to emit gas upwardly therefrom. A plurality of diverters is stacked in a spaced apart relationship directly above the base, each diverter having an inner edge and an outer edge. Each diverter is positioned above a lower diverter so that the inner edge and the outer edge are positioned intermediate one of the inner edge and the outer edge of the lower diverter. The lowest diverter, that which is adjacent the base, is positioned such that the gas ports are positioned directly underlying and intermediate the inner edge and the outer edge thereof.

The invention related to an oxy-fuel torch comprising a handle By which the torch can be manipulated, at least two gas channels arranged through said handle for conveying at least a flow of fuel gas and a flow of oxidizing gas between respective inlets ports and outlet ports, and inlet connectors in fluidic communication with each inlet ports, the inlet connectors being configured to fluidly connect each inlet port to corresponding gas hose via intermediate connection means. According to the each inlet connector is a non-threaded connector and is permanently connected with each inlet port.

An apparatus that regulates the size and intensity of a torch flame by controlling the release of oxygen and a fuel, such as propane. The apparatus releases oxygen and fuel by pivoting a flame control plate that opens and closes mini ball valves using a mini ball connecting bracket. The further forward the plate is pivoted, the more open the valves become increasing the size and intensity of the torch flame. Slotted holes at different angles on the mini ball valve connecting bracket cause the apparatus to release oxygen first resulting in a quiet flame ignition and to release oxygen last to blow out the last flow of fuel, resulting in a safe operation.

A gas combustor includes: a housing, a storage cylinder, a fuel gas controlling device, an igniting device, a safety switch, and a combusting device. The safety switch has a fastening unit and a locking unit abutted against a locking bolt formed on a bottom surface of a press button; the fastening unit has an accommodation chamber allowing the locking unit to be accommodated, and a swing arm having a latching hook and longitudinally disposed at a front end of the accommodation chamber; the locking unit has a main body accommodated in the accommodation chamber, a longitudinal spring is disposed between the main body and the accommodation chamber, and the main body has a push button protruded from a penetrated slot longitudinally formed on a rear wall of the accommodation chamber, and a locking hook protruded towards the latching hook.
