Why pros choose this

TIG (GTAW) filler rods give welders precise control over the weld pool because the filler is fed manually rather than carried in the arc. Choosing the correct alloy and diameter keeps weld chemistry, penetration, and bead appearance consistent across procedures.

From the manufacturer
