FCAW Review

4. Defect caused by trapped hydrogen between slag and weld metal.
5. Gas added to Carbon Dioxide to reduce spatter.
7. Recommended polarity for self shielded FCAW.
8. Transfers current to the wire (two words).
10. Type of wire feeder used with a CV power source (two words).
13. Requires removal after each weld is complete.
14. Electrode and gas travel through this part.
15. self-shielded FCAW does not require this welding gun part
17. Self Shielded FCAW does not use this medium but Dual-Shield FCAW does (two words).
20. This element is included in the flux for self-shielded electrodes to deal with nitrogen absorbed by the weld pool.

1. Type of wire feeder used with CC power sources and self-shielded FCAW.
2. Speed Primary variable that affects the overall size of the weld.
3. Directly tied to Wire feed speed.
6. _____ increases as stickout increases.
9. Type of drive roll recommended for FCAW.
11. Defect caused by too high or too low shielding gas flow rates.
12. Tensile strength for electrode classification is measured in this unit of measure.
16. Shielding medium contained inside the electrode.
18. Travel technique used for FCAW.
19. This function starts the flow of shielding gas without energizing the electrode.
