    摘要： A torch tip assembly of a plasma arc torch is provided for delivering a diffused stream of plasma arc in a gouging operation. The assembly comprises a nozzle including a nozzle body defining a central longitudinal axis extending between a proximal end and a distal end. A nozzle exit orifice of the nozzle body defines at least a bore for conducting the plasma arc therethrough. The assembly also comprises a counter bore feature, disposed relative to the distal end the nozzle body, fluidly connected to the bore and located distally relative to the bore. At least one of the bore or the counter bore feature has a non-circular cross-sectional shape in a plane perpendicular to the longitudinal axis. The non-circular cross-sectional shape is configured to enable a second non-circular cross-sectional shape in the plasma arc that diffuses the plasma arc.

    摘要： An electric arc saw and a method for operating the saw for cutting or slitting metallic objects by melting a narrow kerf into the object. The method provides for determining the minimum threshold current that is necessary to initiate the cutting operation. The normal cutting current exceeds the threshold current and during the cutting operation the blade is advanced through the object at a speed which is continuously monitored and varied as required to maintain the current flow between the blade and the object substantially constant. The arc saw is constructed so that cuts in three mutually perpendicular directions can be made. The blade is mounted to a vertically disposed, hollow piston that reciprocates in a cylinder mounted to and movable along a cross-head. The piston can be pivoted about its axis to align the blade with the different cutting directions. Electric busbars and power lines for rotating the blade extend through the hollow interior of the piston. The blade itself is relatively thin and slightly dished-in so that it assumes a flat configuration during operation.

    摘要翻译： 电弧锯和用于操作锯的方法，用于通过将窄的切口熔化到物体中来切割或切割金属物体。 该方法提供确定启动切割操作所需的最小阈值电流。 正常切割电流超过阈值电流，并且在切割操作期间，刀片以连续监视和速度变化的速度前进通过物体，以保持叶片和物体之间的电流基本恒定。 弧形锯被构造成可以制成三个相互垂直的方向的切口。 叶片安装到垂直设置的中空活塞，该活塞在安装到十字头上并可沿着十字头移动的圆柱体中往复运动。 活塞可围绕其轴线枢转以使刀片与不同的切割方向对准。 用于旋转刀片的电气母线和电源线延伸穿过活塞的中空内部。 刀片本身相对较薄并稍微凹进，使得它在操作期间呈现平坦的构型。

    摘要： Apparatus and a method for cutting a workpiece by a rotary arc saw wherein the residue from the cutting of the workpiece presents atmospheric contamination or the like. The apparatus includes a cutting chamber adapted to contain a fluid coolant which is flowable into and out of the chamber continuously. A rotary arc saw is mounted in the chamber in spaced relationship to a workpiece mount so that, when an arc is established between the arc saw and the workpiece, the workpiece will be progressively cut by the heat of the arc until it is cut to a predetermined depth or is completely severed. An impeller is carried by the arc saw for rotation therewith. The impeller extends below the upper level of the fluid coolant therein and causes circulation of the fluid in the chamber to present a fluid curtain which extends upwardly and across the fluid outlet of the chamber. The residue from the cutting action is caused to circulate in the curtain and to pass out of the chamber to the fluid outlet thereof.

    摘要： A process and device for cutting an electrically conductive workpiece. The workpiece is moved relative to an endless circulating electrode while an electrical voltage is applied to the electrode and the workpiece sufficient to form an arc therebetween for melting the material of the workpiece, which melted material is then carried away by the circulating electrode. The electrode may also oscillate in the direction of relative movement and/or the electrical voltage may be interrupted at certain times such as when the electrode is operable to carry away the melted workpiece material.

    摘要： A portable, hand held electric arc saw has a small frame for supporting an electrically conducting rotary blade which serves as an electrode for generating an electric arc to erode a workpiece. Electric current is supplied to the blade by biased brushes and a slip ring which are mounted in the frame. A pair of freely movable endless belts in the form of crawler treads stretched between two pulleys are used to facilitate movement of the electric arc saw. The pulleys are formed of dielectric material to electrically insulate the crawler treads from the frame.
