Old path, what does that mean, washes out? Chipping off slag?
I'm not very good at explaining things, I guess what I'm trying to say is, if you make a T shape joint with something like 1/8 plate, put a 1/4 gap in the joint, the 6011 will fill the gap better/easier then 7014. So lots of times if I want a nice looking weld I fill gap with 6011 then dress weld with 7014, but on a tight joint I like 7014, less spatter with a clean weld.
