Yanmar's welder-generator set is in fact a rectified DC welder and a revolving field type AC generator. With its large capacity output, this unit has the versatility to handle a wide range of welding currents to suit your job. |
High quality welds can be achieved at low current levels. Voltage fluctuations are small driving welding. The are is easy to keep running, giving high quality continuous welds. Because it is a multiple generator, a reactor becomes unnecessary, allowing substantial weight savings, while reducing the possibility of any trouble at an overload situation. |
||
A “Slow down” mechanism in the dual starting version automatically lowers engine speed during breaks in welding cutting both fuel and lube oil consumption. Combined with Yanmar's already fuel-thrifty engines, running costs are low. |
A large capacity fuel tank is equipped for long hours of continuous operation. The YDW190AE delivers 15 hours of continuous welding operation (at 50 %load, 50Hz) and 11hours of continuous power generation (at rated output) |
||
An efficient frame and useful weight savings. Moreover the Yanmar diesel engine powering this unit is amongst the world's marvel of miniaturization. |
|
||
Every part is designed to ensure maximum durability for many hours of trouble-free operation. At oil pressure drop shut-off system in the dual starting version stops the engine when lube oil pressure falls. |
All control devices and service points are situated on the same side for easy operation and maintenance. Simply key starting and stopping adds to the convenience in the dual starting version. |

The fuel injection system, the heart of the diesel, has been refined through years of research and
development at Yanmar. We have now
succeeded in minimizing the weight and size
and simplifying the structure by adopting a
brushless pump and cutting the nozzle size.
