 For AC-GTAW of Aluminum Alloys,... most of the significant advances focus on new ways to manipulate the AC wave form. These advances largely result from using inverter-based power sources, which allow a welder to extend the balance control, adjusting output frequency and independently controlling current in each AC halt cycle. New inverter-based GTAW machines extend EN balance control, allowing duration from 50 to 90 percent. Making the EN portion of the cycle last longer:* Allows greater weld penetration* May permit increasing travel speeds by as much as 20 percent.* Narrows the weld bead* May permit using a smaller-diameter tungsten electrode to more precisely direct the heat or deposit a narrower weld bead A diesel-powered, high-pressure air compressor is rated at 1,100 cfm and has a pressure range from 150 to 350 psi. The self-contained, 100% oil-free compressor has a "save all" base that eliminates fuel spills and oil leaks, making it one of the most environmentally friendly high-pressure units available. The diesel-driven engine stays well within the boundaries of the EPA and CARB emissions 25gallonaircomptessortanks regulations. A complete line of accessories for the compressor is also available, ranging from aftercoolers to --40[degrees]F desiccant dryers and filters. Air compressor manufacturer, P.K. Lindsay, Deerfield, N.H., has been sold to American Eagle Accessories Group, Garner, la., a division of Stellar Industries Inc. The Lindsay air compressors are sold under the Lindsay and E.L. Smith brand names. All Lindsay compressor assets have been moved to American Eagle''s Garner plant and resumed full production. American Eagle is also 25gallonaircomptessortanks a distributor of various truck-related accessories. According to the company, the FRL series of compressed air filters, regulators, lubricators, and manual control valves provides efficient moisture and contaminant removal, accurate pressure regulation, and precision lubrication for all air-operated equipment applications. All of the components in the series are available individually or in combination units. According to the company, its compressed-air productivity tools cut energy costs by as much as 70%, while reducing 25gallonaircomptessortanks the compressor burden and shop noise levels. A 24-pg application manual shows bow these accessories provide solutions to spot chilling (to -40[degrees]F), dry machining, blow-off, control cooling, air conveying, static, liquid transfer, and spill pick-up. The products meet OSHA noise and dead-end pressure requirements. Welding shops require many types of equipment, including power supplies, guns, torches, wire feeders, flux-handling devices, and accessories such as cables and ground clamps, 25gallonaircomptessortanks as well as consumables-filler metals, fluxes, and shielding gases. For brazing, shops employ furnaces and custom-built fixtures. 3. Welding position. The first performance characteristic to consider. High cellulose coatings, like those on E6010 and E6011 electrodes, generate a light slag that makes for rapid solidifying of the weld metal good for-out-of-position welds. Also good are rutile-fluxed electrodes-E6012 and E6013--that hold out-of-position weld metal in place as it solidifies.4. Welding current. Covered electrodes run on AC, DC, or both. When welding DC, the positive lead typically connects to the electrode (DCEP, or reverse polarity). Some suppliers design electrodes that weld with the electrode negative (DCEN, or straight polarity). Assure the electrode will 25gallonaircomptessortanks perform with the available current.
