Sorry I just saw this. A couple of things here, Push or pull to me is more of a personal thing, as long as like you said the angle is minimal. I do whatever allows me to see it the best for what I am doing. Second- when we were doing some testing for fillet weld breaks for the World Skills the only way to get good root fusion with dual shield was to really drive it in really hard with a high voltage and WFS for the root pass then dial it back down for a really good quality cover pass.
It was really surprising to me to see that but I believe the flux almost blocks the puddle right at the root of the fillet joint. Hope this helps and hopefully next time I can respond faster.
Thanks,
Matt
