TOKYO, Sept. 26. 2013 — Nippon Avionics Co., Ltd. (hereinafter “Avio”), NEC Corporation’s subsidiary based in Tokyo, announced on September 26 the availability of a newly developed, large-capacity inverter-type welding power supply, Model NRW-IN16K4 (*1). This powerful unit provides the high-quality joining of copper (Cu) and aluminum (Al); important materials increasingly being used in the manufacturing of high-capacity motors for electric motorization of automobiles, batteries, and energy-related devices.
New Product Features
- Fuse welding (welding of coil wire and terminals) of large motors that require large current capacity and long welding duration.
- Weld high-conductivity materials, such as Cu and Al, using the efficient control of large current uniquely provided by this new welding inverter power supply system.
- New standard features include a welding waveform graphic color display and waveform memory; an industry first for models offering the same output current level (*2). This convenient display allows easy setting of welding conditions and control of weld quality.
- Maximum welding current of 16,000 amperes is twice the level previously offered by Avio.
- Industry’s longest welding time for same output current capacity level (2) (3); up to 3-second duration.
Multiple Useful Functions
- Accommodates various welding requirements based on its multi control modes
- Stable welding quality based on pre-weld judgment function
- Expanded welding applications with increased memory capacity for up to 255 welding conditions
- Input voltage of 400 V standard is useful in the global market
Setting and Monitoring Functions
- Graphic display of welding waveform simplifies the setting of welding conditions and enhances quality control
- Waveform memory function enables efficient setting of optimum conditions
- Ample monitoring functions contribute to improvement of welding reliability and to stable production
|(*1)||CE Mark approval scheduled in November|
|(*2)||Based on our research as of September 2013|
|(*3)||Maximum current of 9,500A at 3-second welding duration|
- Welding of large motor coil and terminal
- Welding of copper (Cu) bus bar
Avio will concurrently release a new, large-capacity welding head, Model NA-126, to be used with Model NRW-IN16K4 power supply.
