EarthForce America, Summerville, S.C., is the marketing headquarters for Superstav in North America. All machines are sold in North America under the EarthForce brand nameKubota Tractor Corp. USA, an American affiliate of Kubota Corp. in Japan, offers two models of mini-backhoe loaders, the B21 and L35. The company is second in the marketplace and imports its machines from Japan. KTC, which started selling machines in the U.S. market in 1972, is headquartered in Torrance, Calif. The company''s B21 machine is rated 21 hp and features hydrostatic drive, while the L35 is rated 35 hp and has a mechanical Glide Shift transmission for clutchless shifting. The bigger machine has a 9 ft. digging depth. Ingersoll Equipment (not to be confused with Ingersoll-Rand xtremecordlessdrills Co.) is located in Winneconne, Wis. The company started producing small backhoe loaders in 1983. Current models include 18 hp and 20 hp machines and a larger addition is being discussed for 2001. Both the 6018 BH and 6020 BH loaders have a digging depth of 7.5 ft. and both machines are very light at less than 3000 lb.

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 components to be small in size and the power supply xtremecordlessdrills to be relatively lightweight. 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.
