Welding Wire BA-S1 (K415/25) [25Kg Spool]

Our BA-S1 Submerged Arc (SAW) wire is the industry standard for the cost effective welding of mild and medium tensile carbon steels. This low manganese, low silicon solid wire is engineered for high productivity automated systems where reliable, high quality welds are required on everyday structural components.

The S1 classification (comparable to AWS EL12) is specifically designed to be used with active manganese silicate fluxes. This combination provides excellent bead wetting and a clean, smooth finish, making it ideal for the manufacture of structural steel, tanks, and general heavy fabrication. Supplied on industrial grade 25kg K415 wire baskets, this wire ensures maximum "arc on" time by reducing the frequency of spool changes in heavy production environments.

Key Features

Mild Steel Specialisation: Formulated for the welding of common carbon steels where standard mechanical properties are sufficient.

Large-Gauge Industrial Sizes:

- 3.2mm: The versatile standard for heavy structural longitudinal and circumferential seams.

- 4.0mm: Maximum deposition for massive fill passes on thick walled vessels and plates.

K415 Industrial Spool: Heavy duty 25kg wire basket designed for seamless integration with major SAW wire feeding systems.

Stable Arc Characteristics: Provides a consistent, smooth arc even at high currents, resulting in minimal spatter and excellent weld integrity.

High Quality Copper Coating: Precision applied coating ensures superior electrical conductivity and protects the wire from flash rusting during storage.
