Abstract: An plasma cutter, including a power supply, a cutting torch (with a nozzle), a source of air and a valve, is disclosed. The cutting torch is connected to the two power source outputs (cathode and anode). Air is supplied to the nozzle through the valve from the air supply. In one position the valve allows air to flow from the air source to the nozzle. In a second position the valve prevents air from flowing from the air supply to the nozzle and also vents the nozzle and torch. The torch has a movable electrode and the nozzle is in a fixed position. The nozzle and electrode are each electrically connected to a different one of the power outputs. The electrode is biased (preferably by a spring) to be in contact with the nozzle. However, air flowing into the torch and electrode overcomes the bias and moves the electrode away from the nozzle. If the arc is absent and the user desires current, then the valve is moved to prevent air from flowing into the torch and to vent the torch.

Abstract: The present invention relates to a combined support section and an article-support panel for use in conjunction with a vehicle steering wheel. The steering wheel mounted support is devised for detachability mounting thereto and pivotally affix the article-support panel. Additionally, the steering wheel support section also provides the article-support panel with an underside gusseted angle bracing arrangement having an infinitely angular adjustment arrangement. Moreover, located above the article-support panel and integrally provided on the top panel of the support section, receptacles are provided for bindingly engaging and removability receiving thereto of reading material such as a newspaper, book, a magazine or the like. The article-support panel defines a working surface to hold a meal, writing material, a lap top computer or other things that are used in a car.
