Uses both internal flux and external shielding gas (usually CO2cap C cap O sub 2 or an Argon/ CO2cap C cap O sub 2
| Defect | Cause | Solution | | :--- | :--- | :--- | | (small holes) | Contaminated base metal, damp wire, or improper gun angle. | Clean the work surface thoroughly, store wire properly, and maintain a 10-20° drag angle. | | Excessive Spatter | Too much voltage or incorrect stickout. | Adjust your settings and keep stickout between ¾" and 1¼". | | Incomplete Fusion | Travel speed too fast or voltage too low. | Slow down, and ensure voltage/amperage matches your wire size. | | Slag Inclusions | Using a push technique or weaving too wide. | Use a drag (pull) technique and avoid excessive weaving. | | Burnback (wire fused to tip) | Stickout too short or wire feed speed too slow. | Keep proper stickout and balance wire feed speed with voltage. |

FCAW is split into two distinct sub-processes based on how the weld pool is shielded. Choosing between them depends entirely on the working environment and material specifications.
Produces high-quality welds with excellent mechanical properties. Essential Components for Your Work Uses both internal flux and external shielding gas
What are you focusing on (e.g., structural steel construction, shipyard work, or hobbyist repair)?
Can weld through light rust, mill scale, and paint better than MIG. | Adjust your settings and keep stickout between

When preparing your presentation slides, it is crucial to divide FCAW into its two distinct operational methods. Each serves different environments and material requirements. 1. Self-Shielded FCAW (FCAW-S)
Adjust the torch angle to point directly at the joint root and increase travel speed to stay ahead of the slag. 7. Safety Protocols for Industrial FCAW Operations
