Speaking of bad advice, on a single sided butt weld a root gap and bevel is what allows you achieve complete penetration. The filler material is not "bridging" the gap but filling it in.
There is a reason why 95%+ of code weld procedures involving this type of joint and weld process have allowances for a root gap.
Due to the nature of the transfer mode and size of machine being used in this case I would personally go with either a bevel with feathered edges butted tight or a 1/16" land and 1/16" root gap to start.
