Hybrid Battery Tab Welding Machine
- Combination photo of welding head, welding transformer and welding power supply
Suitable for Battery Tab Welding with Advanced Functions － Avio Original New Welding Method! (DC + Inverter)
This new model supplies welding power for battery tab welding featuring Avio's unique hybrid method combining high-speed rising time of a DC type and a high-speed polarity switch of an inverter type. It is equipped with functions suitable for battery tab welding.
High-Quality Appearance and Consistent Welding Strength
- High-Speed Welding
High-speed rising time and high-speed polarity switching enables extremely high-quality appearance, with a minimum heat- effect (burn). - Polarity Switch Function
By minimizing the Peltier effect (Note 1), both welding spots will be of high-quality strength and appearance. Further, consistent heat balance results in longer electrode life.
- Note 1: Influence of Peltier effect and its countermeasure
The Peltier effect has harmful effect for weaker weld strength and faster electrode wear , because of the big heat gap between positive and negative electrode during welding.}
Polarity switching offers uniform heat by alternating positive and negative terminal.

Polarity Switching
- NRW-PS300
Variety of Welding Modes for Stable Welding
- Four Channels Welding
The polarity switch for both Pre-Heat and Main-Heat (Note 2) enables stable and well balanced welding quality.
- Note 2: Pre-Weld, Main-Weld
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.
- Welding Energy Monitoring
By monitoring and feeding back measured welding power, welds of consistent quality are achieved and this function reduces scrapped parts.
Equipped with Useful Functions
- Electric waveform displayed on front color 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. - Welding Waveform Memory
Easy setting of welding condition with welding waveform shown on LCD
