6013 is not a rod that people burning rod for a living will use, the thing that makes it a good starter rod is that is is easy to restart, it has no digging qualities, notice the slag pocket that wont go away, when you get that, stop and grind it out, you also would be better served upping the rod size to one eight, 3/32 is a ***** in any form compared to the same rod of greater size. good looking welds though, have fun, it takes time
