A method for monitoring a flame cutting process includes a preheating phase, a piercing phase following the preheating phase and a cutting phase following the piercing phase, wherein a cutting torch applies a flame generated by combustion of a gas mixture to an electrically conductive workpiece and wherein an electric current flowing between an electrically conductive part of the cutting torch and the workpiece is measured by a current measuring device during a measuring period. An ignition point at which piercing of a hole through the workpiece using the flame starts due to oxidation of the workpiece is detected by a change in the measured current.

A device to unclog orifices in a workpiece is provided. The device includes a lower portion configured to receive the workpiece and an upper portion configured to secure the workpiece to the lower portion. The upper portion includes a tube configured to receive a piston. An unclogging material is placed in the tube portion, and the piston forces the unclogging material through the orifices.

The present invention relates to a method of manufacturing a bifurcated pipe and a bifurcated connector for connecting hoses and a fuel supply hose manufactured using the same, in which connection between a torch and an oxygen tank or a gas tank is facilitated and hoses are prevented from becoming twisted or entangled during a welding or cutting process.

Further, according to the present invention, a single connection hose is prevented from being damaged by sparks, a piece of steel cut off the workpiece, a discarded welding rod, or a sharp cut surface or edge of the workpiece, and a worker is capable of easily recognizing gas leakage and a portion from which gas is leaking, thereby preventing an accident.

A protective cutting torch tip cover system is provided, for use with an oxygen and acetylene cutting torch having a conical torch tip having a plurality of ports through which oxygen and acetylene gases pass prior to combustion, which includes a generally conical shaped cover formed of elastomeric material and configured for elastic frictional engagement with said cutting torch tip and a protective cover storage device for holding the protective cover up and away from the torch flame when not installed on the torch tip.

In some aspects, autonomous motion devices configured to operably connect to a plasma torch of a plasma cutting system can include: a body to support a power supply of the plasma cutting system and move relative to a workpiece; a torch holder connected to the body and configured to position a plasma arc torch tip of the plasma torch relative to a region of the workpiece to be processed; a drive system to translate the body supporting the power supply and torch autonomously relative to a surface of the workpiece during a plasma processing operation; and a processor in communication with the drive system and configured to communicate with the power supply, the processor being configured to control the translation of the body relative to the workpiece in accordance with the plasma processing operation.

A laser working machine includes a first slot provided at another end portion of a first body. In the first slot, either one of a first shielding plate and a first light transmissive plate is selectively insertable in a sealed manner. The first shielding plate is configured to block a first optical path. The first light transmissive plate has a first optical path hole through which the first optical path and a second optical path are connectable. The laser working machine includes a second slot provided at a second body end portion of a second body. In the second slot, either one of a second shielding plate and a second light transmissive plate is selectively insertable in a sealed manner. The second shielding plate is configured to block the second optical path. The second light transmissive plate has a second optical path hole.

A device and system comprising a cutting torch system including a multi-fuel adapter specially adapted to convert a gasoline oxygen cutting system to a multi-fuel cutting system and methods of using the same. The invention also includes a portable system including a carrying case for use with the multi-fuel adapter.

A method and machine for cutting and removing a workpiece part from a plate-shaped material includes cutting the workpiece part with a beam or jet directed onto the material and separating the workpiece part and material. The workpiece part is removed as a scrap skeleton removal part. The cut-free workpiece part is lifted out of a workpiece supporting plane by a lifting device and removed by a gripping device, or the cut-free workpiece part is removed downwards from the plane through a gap between workpiece supporting surfaces by an ejection device, or gravity removes the cut-free workpiece part downwards through the gap. Before cutting the workpiece part free, a sacrificial part adjoining the workpiece part and partially having a common cutting line with the workpiece part is cut free from the material before cutting the workpiece part free in the material or scrap skeleton.
