Refers to how the slag follows the puddle. If the slag is close, it ?crowds? the puddle, making it more difficult for the welder to observe the arc. If the slag follows fast, it allows for faster travel speeds. ?Good? slag follow is when the puddle is clear with the travel speed at a rate that keeps the puddle oblong.
