Excellent close-up arc shots, JD. I see the dangers of the flux running ahead of the puddle, and I can see why the manipulation helps avoid that. No doubt you act on instinct when you see the flux getting ahead, so you might not even know what you instinctively do to combat it, but when you do see flux getting ahead, what’s the immediate action you do to stop it? Or put it another way, if I saw the flux suddenly appear in front of the rod, my immediate action would be to check my drag angle and if I’ve lost it and gone too much straight in, I’d increase the drag angle; I’d also immediately do some manipulation of the arc, and I think I’d also possibly try to reduce the arc gap. Now, are those the right things to do? Which is the most likely to fix the problem, or the thing I should do first - drag angle, manipulation, or both at the same time?
Is there any link between welding current and flux getting ahead? Is it possibly a sign that the welding current is too low?
