 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 perform with the available current. 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 airsudpensiontank environmentally friendly high-pressure units available. The diesel-driven engine stays well within the boundaries of the EPA and CARB emissions regulations. A complete line of accessories for the compressor is also airsudpensiontank 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 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 airsudpensiontank pressure regulation, and precision airsudpensiontank 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 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. airsudpensiontank 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, as well as consumables-filler metals, fluxes, and shielding airsudpensiontank gases. For brazing, shops employ furnaces and custom-built fixtures. Transformer-rectifiers have moveable parts that/end to wear out. However these machines airsudpensiontank can produce some of the best arc characteristics.A silicon-coated-rectifier (SCR) power source, electronically voltage-controlled, has no real moving parts other than the primary current contactor and cooling--fan the only parts that will wear out. If fabricator requires pulsed welding, the SCR power source starts to show its limitations and inverters become the power supply of choice.AC-DC inverters, which convert AC in put frequency to very high frequencies--up to 1,000 times that of input frequency--allow transformers and other components to be small in size and the power supply to be relatively lightweight. airsudpensiontank This high operating frequency enables the inverter to precisely control output power and to deliver smooth arc initiation with minimal or no spatter. Current ripple is low for a very stable arc:, even at low amperages. And the improved arc control can, in some cases, minimize electrode overheating and fume emissions. Finally, the smallish transformer allows for more efficient use of primary power compared to conventional power supplies. Searching for accessories for your air compressor?
