: Ensure the top edge of the weld blends smoothly into the plate without leaving a grooved, weakened edge. : Leather boots should be laced tightly, and

Strike your arc and let the puddle form. Because you are fighting gravity, you must keep the weld puddle . Common Issues and Fixes Problem Likely Cause Undercut

Success in the 4F position requires precise control over heat and the weld puddle to prevent sagging or dripping.

: The molten metal rolls over onto the bottom plate without properly fusing to it. This is caused by a travel speed that is too slow or an amperage setting that is too low.

A groove melted into the base metal along the toes of the weld that is left unfilled.
