You don't have enough power to leave the rod in the puddle - concentrate on getting an equal leg fillet in the root.
More arc needs to be directed at the lower plate than at the edge (the edge takes less heat to melt).
Watch the puddle wet out, feed a little rod, move forward, watch it wet out, feed rod, repeat.
I would be using 150 amps and motoring out on that thickness - but since you're using less, patience is the key.
After a really nice tight root pass - the second one on a now warmed up plate will finish the job
