    Torch for working underwater and capable of cutting steel, concrete etc. having a tubular oxygen lance (10) to be connected to an oxygen source (24, 25): said lance is provided with a handle (16) having the shape of a gun. In order to safely light the torch under the water, the lance has a sealing device (12) that is blown up or melted by an ignition device (14) actuated under the water, by firing at the same time the oxygen coming out of the lance (10). The sealing device (12), located at the free end of the lance (10) is comprised preferably of a plug made of an easily inflammable material or of a material containing such easily inflammable material.

    The invention relates to devices for cutting metals or non-metals, in particular to an underwater cutting device.
    The purpose of the invention is to increase the reliability of the underwater cutting device.
    Figure 1 schematically presents the proposed device with chemical ignition; figure 2 - the same, with electric jingani; in fig. 3 - a chemical agent; on - electric ignition means.
    The proposed underwater cutting device contains an oxygen source 1, a tubular oxygen lance 2, at the working end of which a plug 3 of flammable substance 4 is mounted, for example, of an iron term coated with a sheath, for example, of insulating varnish or in the form of a plastic cap, and at the non-working end a waterproof sheath 5 is placed, with which a needle 6, made, for example, of rubber or plastic tubular, interacts in rcc 7, with axial movement and is connected an oxygen source 2 through a hose 8 with a reducing valve 9 placed in it. In addition, the device contains a control lever 10 fixed on the rim 7 with the possibility of rotation and interactions with the tubular needle b, and the burner means, which is made in the form of a thin-walled a glass bead 11 with a chemical reagent, for example, concentrated sulfuric acid,

    placed inside the plug 3 of a flammable substance, or in the form of a power source, such as a battery, and connected to its poles
    5 filaments 12 glowing. In the latter case, the device is equipped with an electric switch 13 connected to the ignition means, still mounted on the handle 7, and the control lever 10 is installed with the possibility of interaction with it. The tubular oxygen lance 2, and the handle 7 are connected using a conventional cartridge 14.
    tS The device (Fig.1 and 3) works as follows.
    When the control lever 10 is moved in the direction of the tubular handle 7, the needle 6 moves toward the working end 20 of the oxygen lance 2 and pierces the waterproof sheath 5, as a result of which oxygen penetrates the cavity 2 and destroys the glass ball 11, as a result
    25 of which sulfuric acid is produced, causing ignition of a flammable substance, leading to the removal of plug 3. Then the operation of the device begins.
    properties.
    In the case of a variant of the device according to FIGS. 2 and 4, the movement of the control lever IO. Towards the driver 7 leads to the fact that the needle b punches the sheath 5, as a result of which oxygen passes into the cavity of arm 2. with an electric switch 13, which initiates a switch. flaming.
