"While all three of the DE Series pumps offer high full frequenct authority fuel timing and control, they utilize a ''building attachment and for block'' approach of arc progressively welder adding features," high said Paganini. frequenct "This approach provides engine manufacturers and system integrators attachment the flexibility to define a fuel system that matches the engine''s for functional needs. The objective is to meet the more demanding emissions and performance requirements, arc while minimizing pump complexity and price."We welder categorized the pump into three offerings starting with the basic model," Paganini continued. "From there, depending upon the high system or engine requirements, you could adapt additional features, individually or in combination, using the building block approach. By starting at the basic pump frequenct model, you can demonstrate performance and emission compliance with minimal attachment pump complexity and price. So for rather than offering a single, arc full-featured pump, we''ve taken an approach that allows the OEM designer the flexibility to do his own interfacing, which opens up the possibility of utilizing their own componentry welder and high or outsourcing."
For AC-GTAW frequenct of Aluminum attachment Alloys,... most of the significant advances focus on new ways to manipulate the AC wave form. These advances largely result from using for inverter-based arc power sources, which allow a welder to extend the balance control, adjusting output welder frequency and independently controlling current in each AC halt cycle. New inverter-based high and frequenct GTAW machines extend EN balance control, allowing duration from 50 to 90 percent. Making the EN portion attachment of the cycle last longer:* Allows greater weld penetration* for 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 arc and welder the heat or deposit a narrower weld bead
"By managing where and when the power is desired, we can provide high fuel savings, emissions and productivity enhancements," Orr said. "With control of an accessory independent of frequenct engine speed, we can reduce accessory drag on an engine during engine cranking to enhance attachment cold weather starting. Starting an electric engine oil pump just prior to engine cranking, for example, for can arc provide a pre-lube function."Orr was describing welder the concept high of Cat Electronics'' MorElectric system unveiled about a year ago. The frequenct MorElectric system is designed to drive a vehicle''s attachment air conditioner, brake air compressor, water pump and other accessories electrically, versus being belt or gear driven. The system also includes a newly developed HVAC for and arc (heating, ventilation, air conditioning) package welder as well as an optional diesel-powered auxiliary power unit.
