 Saw Uses CV or CC Power Supplies,... 200 to 1,500 A, 28 to 44 V, at 60- to 100-percent-duty cycle. Automatic units commonly use up to 1,500 A on one wire. Cv welding machines that offer variable-slope control give the welder extra adjustability, and can extend the usefulness of the machine to weld a range of material thicknesses and types.Selection of Power SourcesWhen choosing a power source, start by checking NEMA specs. NEMA Class I arc-welding power sources deliver rated output at 60-, 80-, or 100-percent-duty cycle: Class II units, 30-, 40-, or 50-percent; and Class III, 20 percent. First consider capacity and kind of current needed for the job. Rely on the manufacturer''s rating as being conservative: don''t buy more capacity than needed. Choose low--duty-cycle machines only for maintenance or for intermittent welding. If portability is important, consider inverter units. 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 aluminumairgank well aluminumairgank within the boundaries of the EPA and CARB emissions 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. aluminumairgank The Lindsay air compressors are sold under the Lindsay and E.L. Smith brand names. All Lindsay compressor assets aluminumairgank 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 aluminumairgank filters, regulators, lubricators, and manual control valves provides efficient moisture and contaminant aluminumairgank 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 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, as well as consumables-filler metals, fluxes, and shielding gases. aluminumairgank For brazing, shops employ furnaces and custom-built fixtures. Power SuppliesWelding power supplies take alternating or direct current from a power line aluminumairgank or portable generator and convert it to current usable at the welding arc:, Check National Electrical Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction and performance aluminumairgank requirements of individual machines.Among types of power supplies, alternating-current (ac) transformers are least costly-most use 230 V single phase input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or variable voltage (vv). aluminumairgank AC-DC transformer-rectifiers can AC and DC weld.
