20090289596 | CHARGER PLUG WITH IMPROVED PACKAGE - A reduced plug-size charger plug for power conversion is disclosed utilizing a pair of blades that are slidably mounted into a charger housing, obviating the need for insertion molding. To promote and maintain electrical contact while minimizing package size and charger plug cost, a pair of spring contacts are provided for electrically connecting the blades with internal circuitry. | 11-26-2009 |
20090294413 | METHOD AND APPARATUS FOR PROPORTIONAL VALVE ACTUATION IN A PLASMA CUTTER - 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. | 12-03-2009 |
20100078410 | METHOD AND APPARATUS FOR HIGH POWER DENSITY PLASMA CUTTING SYSTEM - 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). | 04-01-2010 |
20110254506 | HOUSING CONFIGURATION FOR CHARGER PLUG - A reduced plug-size charger plug for power conversion is disclosed utilizing a pair of blades that are slidably mounted into a charger housing, obviating the need for insertion molding. To promote and maintain electrical contact while minimizing package size and charger plug cost, a pair of spring contacts are provided for electrically connecting the blades with internal circuitry. | 10-20-2011 |
20130206735 | CONSUMABLE SELECTION AID FOR A PLASMA CUTTING SYSTEM - A plasma cutting or welding system includes a power input. The power input is configured to be coupled to a plurality of multipronged input plugs. Each of the multipronged input plugs corresponds to an input voltage. The power supply also includes a user input device for selecting an operating current. The user input device is subdivided into a plurality of current ranges. Each of the current ranges includes an iconic representation of at least one multipronged input plug. | 08-15-2013 |

20150190876 | WELDING STAND FOR A WELDING SYSTEM - A welding system includes a motion tracking system comprising a camera having a lens. The welding system also includes a cover disposed over the lens of the camera. The cover is configured to enable infrared light to pass therethrough and to block environmental elements from contacting the lens of the camera. The cover is disposed over the lens of the camera at an angle relative to a face of the camera, and the angle is between approximately 10 and 60 degrees. | 07-09-2015 |
20150190887 | CALIBRATION TOOL AND METHOD FOR A WELDING SYSTEM - A calibration tool includes a calibration tip. The calibration tool may be for a welding training system or some other welding system. The calibration tool also includes a first marker disposed a first distance from the calibration tip and a second marker disposed a second distance from the first marker. The second distance is adjustable during calibration. | 07-09-2015 |
