Shaping systems and methods suitable for cutting a material and deburring devices for performing a deburring operation on an edge of the material. The shaping systems include means for supporting the material and at least first and second carriage units independently operable to travel parallel to an axis of the supporting means. The first carriage unit comprises a cutting device coupled thereto with a first arm, and the second carriage unit comprises a deburring device coupled thereto with a second arm. The cutting device and the deburring device are coupled to the first and second carriage units, respectively, so as to move in a travel direction relative to the material supported by the supporting means and perform cutting and deburring operations, respectively, from opposite surfaces of the material.

A system for performing exothermic operations or oxygen delivery uses a rod and handle configuration to create a flowpath of oxygen. The rod includes cables having stainless steel fibers that burn using the oxygen within a hollow center area. While burning, the rod cuts through material. A sheath covers the covers to contain the gases and prevent unraveling of the cables. The handle attaches to the rod and provides control of the flow of oxygen to the rod. A manifold fixing in place bottles of oxygen connects to the handle and can be fixed to provide different mixtures from different bottles. The rod is disconnected when needed to fix a mask thereto for delivering breathable oxygen to a patient.

A torch cutting machine comprising a longitudinal travel way, a main carriage that travels along the travel way, and a boom assembly extending from the main carriage perpendicular to the travel way, the boom assembly comprising at least one cutting torch extending from a main boom. The boom assembly is rotatable with respect to the main carriage. Also, a method of cutting metal material where a boom of a torch cutting machine having a cutting torch extending therefrom, is placed over metal material in a first cutting bed, which is cut by moving the cutting torch. The boom is rotated 180 and positioned over material in a second cutting bed, which is cut in the same manner. Cut material is removed from the first cutting bed and new material is placed in the first cutting bed while the cutting of the material in the second cutting bed is being performed.

A welding or cutting tool for welding or cutting electrically conductive workpieces includes a nozzle arranged on a tool tip for discharging a welding or cutting beam and a nozzle cap which at least partly surrounds the nozzle, is open towards the tool tip, and has an electrode that forms a capacitance with the respective workpiece and an insulating element that electrically insulates the electrode from the other components of the tool. The electrode consists of a first electrically conductive ceramic material and is formed integrally with the insulating element, which consists of a second electrically insulating ceramic material.

A plasma arc torch is provided that includes a torch body and a torch height controller. The torch height controller includes a movable part mounted to the torch body and a fixed part connected to a robotic arm. The movable part and the torch body are biased toward a workpiece and are translational relative to the fixed part.

An assembly removably securable to a welding apparatus or a cutting apparatus is disclosed. The assembly includes a circular disc, a clamp removably securable to either apparatus, a cylindrical member secured to the clamp, and a shaft having opposite end portions. One of the end portions is rotatably mounted to an end portion of the cylindrical member. The other of the end portions has the circular disc rotatably mounted thereto.

A pipe cutting assembly and method of use thereof for cutting level vertical pipes is provided. In one form, the pipe cutting assembly includes an adjustable arm including: at least one horizontal guide body movably mountable to and radially extending from a circular guide of the pipe cutting assembly; at least one vertical guide rail slidably mountable to the at least one horizontal guide body and horizontally moveable relative thereto; and a cutting torch mount for mounting a cutting torch, said mount slidably mountable to the at least one vertical guide rail and vertically moveable relative thereto.

An oxy-fuel system for supplying a torch with a fuel gas stored under pressure in a container includes the following components: (a) an upstream fuel gas supply line between the container and the torch; (b) a demand valve arranged in the upstream fuel gas supply line; (c) the torch connected to an oxygen supply line. The torch includes a venturi nozzle adapted to generate in the upstream fuel gas supply line a negative pressure P.sub.negative of at least 0.3 bar relative to atmospheric pressure in operating condition, and the demand valve is vacuum-controlled and configured to have a pressure setpoint to open the demand valve, the pressure setpoint being negative relative to atmospheric pressure and equal or less negative than P.sub.negative.
