Nippon Avionics Co. Ltd. has announced the availability of a newly developed, large capacity inverter type welding power supply, Model NRW-IN16K4. 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 include 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. This convenient display allows easy setting of welding conditions and control of weld quality. Various welding procedures, including welding quality and productivity, are easily implemented by selection of constant current, constant voltage or constant power modes.

Abnormality of welded object or electrode can be detected by flowing extremely small current for a short time and measuring the resistance between the objects to be welded before the actual welding process. This avoids damage to products and to the welding electrode due to sparking. Multiple welding points can be welded under different welding conditions, for example, in the production of motors.

Input Voltage of 400 V Standard is Useful in the Global Market.
