  • Publication number: 20150129787
    Abstract: A system for positioning a seal member on a movable valve stem. The system includes an O-ring surrounding a lower portion of a movable valve stem. A snap-on retaining collar is pushed into place along the valve stem. A lower edge of the collar contacts the O-ring. The interaction between the snap-on collar and the O-ring prevents the O-ring from flexing outwardly and becoming dislodged from the valve stem. The snap-on retaining collar can be formed from various materials, such as but not limited to plastic.

  • Patent number: 8754348
    Abstract: A system and method for automatically controlling gas pressure for a plasma cutter includes a plasma torch, a gas supply system to provide a pressurized gas to the plasma torch, and a proportional valve configured to regulate the pressurized gas. The proportional valve includes a body, a valve seat positioned therein and defining a valve orifice, and a plunger having a mating surface on one end that mates with the valve seat and the orifice and a pressure receiving surface on an opposite end. The proportional valve also includes an inlet to receive the pressurized gas and distribute the pressurized gas to the valve orifice and the pressure receiving surface of the plunger, an electrical solenoid having a chamber to electro-magnetically translate the plunger therein, and a bias urging the plunger toward the valve orifice in conjunction with the pressurized gas when electrical power is reduced to the electrical solenoid.

  • Patent number: 8637786
    Abstract: A system and method for providing a high power density plasma cutting/welding-type system is disclosed. The plasma cutting system includes a housing and a power source disposed within the housing constructed to generate plasma cutting power. The plasma cutting system also includes a plasma torch actuated by a trigger and connected to the power source to produce a cutting arc. The plasma cutting system is constructed such that it has a power-to-weight ratio of at least 550 Watts per kilogram (W/kg).
