| Defect | Cause | Fix | | :--- | :--- | :--- | | | Moved too fast across center; too much angle upward. | Slow down. Pause longer on the sides. | | Overlap / Cold Lap | Travel speed too slow; puddle rolling over without fusing. | Increase heat (amperage) or speed up slightly. | | Excessive Sagging (Drip) | Too much heat; puddle too large. | Reduce amperage; use a smaller electrode; pause less in center. | | Slag Inclusion (Stick/FC) | Slag ran ahead of the puddle. | Keep arc on leading edge; use a slight drag angle. | The 3F position is considered a rite of
