Abstract: Provided is a welding-type power source, comprising power conversion circuitry configured to convert input power to welding-type power, a user interface comprising a first input device, a second input device, and an output device, and control circuitry. The control circuitry is configured to, in response to a first input via the first input device, control the output device to output an indication that the welding-type power source is in a preconfigured state, set predetermined ones of welding-type parameters to respective predetermined values, set a welding current, when there is an input from the second input device, to a value indicated by the second input device, and set the welding current, when there is not an input from the second input device, to one of: the default value when the default welding current has not been changed, or a welding current that has been changed previously via the second input device.

Abstract: Welding systems including welding torch assemblies are provided. The welding torch assembly may include a welding torch adapted to be utilized in a welding operation to establish a welding arc between the welding torch and a workpiece. Shielding gas may be supplied to the welding torch for establishment of a gas shielding area around a weld pool. The welding torch assembly may also include a temperature sensing system having a non-contact temperature sensor coupled to the welding torch and adapted to sense a temperature of the workpiece at a location outside of the molten weld pool.

Abstract: Provided is an electrically isolated pump system that comprises welding-type power conversion circuitry configured to convert input power to welding-type power, a motor configured to output mechanical power using motor voltage derived from the input power by a motor power conversion circuitry, and an electrically insulating isolating coupler configured to transmit the mechanical power to a pump, where the motor is electrically isolated from the pump and the pump is configured to use the transmitted mechanical power to pump fluid.

Abstract: A method and apparatus for providing welding type power is disclosed. The welding type power supply has fours sides, a top and a base. Two opposing of the sides and the top are part of a housing. A front panel and a back panel form the other two opposing sides. The front and back panel and the housing are joined such that the front and back panels and the first and second sides form the four sides of the welding type power supply. The base is comprised of extruded material, and has a first edge and a second edge. The first edge is joined to a bottom of the first side and the second edge is joined to a second bottom of the second side. Power and control circuitry disposed in the space formed between housing, front panel, back panel and base.

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.

Abstract: The present invention is related to a cable management system for a plasma cutter. The cable management system uses a flexible strap that is affixed to the housing of the plasma cutter and a loop is formed in the cable. The loop can be opened to align and position the cable with respect to the strap and the loop then can be easily closed to encircle the cable to secure the cable to the housing of the plasma cutter. By the present system, the portable plasma cutter can be transported by a user and the cables are securely fastened to the housing so as to prevent the cable from dragging or otherwise present a burden to the transportation of the plasma cutter.
