  • Patent number: 12151322
    Abstract: Provided herein is a quick disconnect torch handle for use in a plasma arc system. In one approach, the plasma arc system includes a lead having a first end connected to a power source and a second end connected to a torch handle. The quick disconnect is located at a proximal end of the torch handle, and may include at least one signal connection, a pilot connection, a fluid connection, and a main power connection. The fluid and power connection may be formed by a connection between a main power socket and a conductive conduit. Specifically, the main power socket includes a conductive spring and an O-ring encircling an interior bore thereof. Removal of the conductive conduit from the main power socket causes the fluid connection to break between the O-ring and the conductive conduit, and then the power connection to break between the conductive spring and the conductive conduit.

  • Patent number: 12096594
    Abstract: A heat extraction assembly or apparatus includes a cooling cassette and a component coupled to a top surface of the cooling cassette. The cooling cassette may include an inlet, an outlet, and a cooling cavity disposed within the top surface of the cooling cassette. The cooling cavity may be in fluid communication with inlet and the outlet. The component may be coupled to the top surface of the cooling cassette proximate to the cooling cavity such that the component at least partially defines a boundary of the cooling cavity. Coolant flowing through the cooling cassette from the inlet to the outlet may directly contact the component at the cooling cavity in order to provide a cooling effect to regulate a temperature of the component.

  • Patent number: 12017294
    Abstract: An electromagnetic component assembly disposed in a power source of a welding or cutting system. The electromagnetic component assembly includes a core and a tubular winding. The tubular winding is placed near or around the core and conducts a current for an electromagnetic operation. The tubular winding includes a passageway for a process fluid, an inlet, at one end of the passageway, that receives the process fluid, and an outlet, at another end of the passageway, that directs the process fluid downstream toward a torch assembly. The passageway enhances cooling of the electromagnetic component assembly as the process fluid travels through the passageway from the inlet to the outlet.

  • Patent number: 11974384
    Abstract: Consumables for cutting torches include consumables that define a parallel plasma channel and/or a steep, elongated plasma chamber. Additionally, the consumables may define smooth, rounded edges between different geometries of the plasma channel (e.g., at transitions between straight and angles sections) and/or between the plasma channel and the plasma chamber. That is, the consumables may provide a plasma channel that does not converge, diverge, or define any corners and/or a plasma channel that transitions to the plasma chamber without defining any corners.
