FCAW can be performed in which modes?

• A. Manual only
• B. Semi automatic or fully automatic
• C. Automatic only
• D. Handheld only

Answer: (B)

FCAW modes refer to how the welding wire feeding and torch movement are controlled. In manual mode, the welder holds and guides the gun and feeds the wire by hand. In semi-automatic mode, the operator still guides the torch, but the wire feed and/or travel are controlled by a machine. In automatic mode, the torch travel and wire feed are fully controlled by equipment, such as a wire feeder or robot.

The best choice reflects the common, machine-assisted ways FCAW is performed: semi automatic or fully automatic. These modes cover the practical, production-friendly setups where automation aids consistency and productivity. The other options imply only a single form or handheld-only operation, which doesn’t capture the typical range of FCAW practice.
