Description
NIHONWELD N-AL-4 is a versatile aluminum welding electrode designed for general-purpose welding of aluminum alloys in repair, maintenance, and fabrication applications.
The electrode features a specially formulated flux coating that provides excellent arc stability and smooth slag fluidity while allowing easy removal of surface oxides during welding. This helps improve weld quality and ease of operation, especially in aluminum welding where oxide contamination is a common challenge.
N-AL-4 is hermetically sealed in tin can packaging to improve shelf life and maintain product quality during storage and handling.
