I use an in and out whip motion for fillet and lap joints with 6011 that 's much more 'active' than when using 13 for the same joints. You must do this with 11 if your amperage is turned up for deep penetration since it is a deep penetrating rod to begin with. With 6013 you can create a very uniform bead with little movement; hence the drag description. 13 can produce very wide, uniform beads using a modified halfmoon motion that is nearly sraight with slight hooking at the tips of the halfmoon and progression at each end. 13, when the amps are right, will procuce the lap and fillet joints with essentially zero movement with a resulting bead of acceptable width. 6011, when used in this manner, produces a very narrow, deep weld. The in and out motion that controls the penetration and bead size/placement with 6011 can produce slag inclusions with 6013 as it is not a low-slag, quick freezing rod. When used properly 6013 will produce those 'picture-book' welds that you like to leave un-ground and barely painted! You can probably see very quicky the difference in the two rods by simply running a few UPHAND (weld progresses from the bottom upwards on a vertical joint) welds on 2 pieces of scrap 1/4" plate arranged in 'Tee' fashion. Run a bead up with both rods; your electrode should be about 20-30 degrees off vertical . The halfmoon whip with a pause in center (just above the 'shelf' to provide penetration at the root of the joint) and quick up-stoke left, back to shelf, quick up-stroke right, back to shelf, etc. will show how the quick-freeze and low-slag characteristics of the 6011 come into play in 'out of position' welding. The ability to get out of the puddle as it tries to droop and right back into it without slag inclusions makes it my choice for overhead, vertical and gap welding. I'm not downgrading 6013, it's just that most of my uses require 6011's properties and, due to experience, I can make 6011 welds that are 'purty' enough for who it's for....me. :-)
