The NRW-PS300 model supplies welding power for battery tab welding featuring a unique hybrid method combining high-speed rising time of a DC model and a high-speed polarity switch of an inverter model. The power supply is equipped with functions suitable for battery tab welding. High-speed rising time and high-speed polarity switching enables extremely high-quality appearance, with a minimum heat-effect (burn).

With the Polarity Switch function the Peltier effect can be minimized. Both welding spots will be of high-quality strength and appearance. Further, consistent heat balance results in longer electrode life. Equipped with four welding modes: Pre-weld and other variety of welding modes. The polarity switch for both Pre-Heat and Main-Heat enables stable and well balanced welding quality. The pre-weld function allows conditioning of the materials prior to welding, and a check of the resistance of the materials to be welded. By removing oxidized membrane from the surface as well as by smoothing contact surface of objects at the pre-weld stage, the main-weld becomes much more stabilized. By monitoring and feeding back measured welding power, welds of consistent quality are achieved and this function reduces scrapped parts.

Useful functions: the electric waveform displayed on front colour monitor allows simple and easy setting and checking of conditions. Up to eight waveforms can be displayed, which is useful when trying to determine the best welding condition. Equipped with a welding waveform memory. Easy setting of welding condition with welding waveform are shown on the LCD display.
