How can filler wire be fed in GTAW?

• A. Manually or automatically
• B. Only manually
• C. Only automatically
• D. Not used at all

Answer: (A)

In GTAW, filler wire can be added in two ways: manually or with an automatic wire feeder. In manual TIG welding, the filler rod is held with a tongs and fed into the molten pool by hand, with the deposition rate controlled by the welder’s feeding speed and distance from the arc. In TIG welding with a wire feeder, a spool of filler wire is fed automatically into the arc at a controlled rate, providing consistent deposition and is common in automated or high-speed applications. Some setups let you switch between these modes as needed, or use both depending on the weld requirements.
