 Martz, who produces grain and livestock on a 430-acre farm, was using a pair of mccullochpromac610chainsawparts 300-gallon tanks on overhead stands for gasoline and diesel storage. The facility, shown on the next page, was typical of systems on many farms. However, while serving on the Boone County Soil and Water Conservation Board, Martz became aware of its potential environmental hazards."We''ve been on this farm since 1960, and the fuel tanks were put in place about then," says Martz. "We haven''t had any major leaks or spills, but it''s easy to see how something like that could happen. The tanks we''re putting in are much safer." Transformer-rectifiers have moveable parts that/end to wear out. However these machines 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 mccullochpromac610chainsawparts components to be small in size and the mccullochpromac610chainsawparts power supply to be relatively lightweight. This high operating frequency enables the inverter to precisely control output power and to deliver smooth arc mccullochpromac610chainsawparts 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. Looking for a chainsaw for sale?
