What equipment is used for FCAW?

• A. Equipment used is the same for GMAW (constant voltage power source and speed wire feeder)
• B. Separate dedicated FCAW power supply
• C. Only DC welding machine
• D. Hand-held gun with no power source

Answer: (A)

FCAW uses the same basic welding setup as GMAW: a constant-voltage power source and a wire feeder. The flux-core wire itself provides shielding in self-shielded FCAW, or shielding gas can be used with FCAW-G, but the machine arrangement—CV power and wire feed—remains the same. That’s why the standard approach is to use the same equipment as GMAW. The other options imply unnecessary extra gear (a separate FCAW power supply), or an impractical setup (a hand-held gun with no power source), or an overly restrictive claim about the power type, which isn’t accurate because FCAW relies on a constant-voltage supply rather than a special, dedicated unit.
