Abstract: A method and apparatus for controlling a gas supply to a plasma arc torch uses a proportional control solenoid valve positioned adjacent the torch to manipulate the gas flow to the torch, thereby extending electrode life during arc transfer and shutdown. Swirl ring design can be simplified and gas supply and distribution systems become less complicated. The invention also allows manipulation of shield gas flow to reduce divot formation when making interior cuts. The system can be controlled with a digital signal processor utilizing a feedback loop from a sensor.

Abstract: A trash bag holder comprising a collapsible frame having a plurality of elongated support members flexibly connected end-to-end. A trash bag is secured to the frame by the use of a plurality of clips mounted on the frame. The frame engages the trash bag in a manner which holds the mouth of the trash bag open when the frame is in a ready-to-use configuration. The frame is maintained in the ready-to-use configuration by a brace pivotally mounted to one of the support members and releasably engaged to a second support member. To collapse the frame, the brace is disengaged from the second support member thereby allowing the support members to be collapsed into a convenient and compact size for transport or storage. A handle is attached to one of the support members to allow a person to maneuver the trash bag holder into any desirable position. The support members are optionally adjustable in length to allow for the use of trash bags of varying sizes.
