Wire for General Fabrication

Weld Star SG1 is a copper-coated TIG welding wire formulated for carbon and carbon-manganese steels. With moderate levels of silicon and manganese, it provides smooth arc characteristics, good weld bead appearance, and is especially suited for thin sheet and general structural work.

This wire is ideal for both single-pass and multi-pass applications across a wide variety of industries, delivering consistent mechanical properties and excellent operability.

Manufactured from virgin raw materials ("green wire") for superior consistency, purity, and feedability.
