Applications

TIG (GTAW) filler rods are used in the gas tungsten arc welding process, where the welder manually feeds the rod into the weld pool while maintaining the arc with the torch. TIG welding produces the highest quality, lowest spatter welds and is the process of choice for precision work on stainless, aluminum, titanium, and exotic alloys.

Compatibility & sizing
  • Electrode type: TIG Rod
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
