What is the recommended inclination for the FCAW fill pass in the 1G position?

In the flat (1G) position, how you angle and orient the torch shapes the molten pool and how the filler metal wets the joint. For FCAW fill passes, a backhand (drag) motion with a shallow travel angle—about 0 to 10 degrees—gives you a stable puddle and a well-formed, evenly deposited bead. Dragging the arc toward the joint helps with penetration control and bead shape, which is important when building up multiple passes. Pushing the torch at a higher forehand angle (0–10 degrees is shallow, but 15–25 degrees is steeper) tends to push the pool ahead of the weld, leading to shallower penetration or less even deposition for fill passes in the flat position. A steep backhand angle (45–60 degrees) would produce a narrow, elongated pool and poorer control. So the best choice is a backhand motion with a shallow angle of roughly 0 to 10 degrees.
