If your beads are too ropey...you have too much wire feed for the heat setting...or you are traveling too slow.
If you are pulling the gun...the beads also tend to rope up.
Flatter beads are easier when you push the gun..
Ropey beads (or poor wetting in the edges) can also be caused by welding on cold metal with mickey wire.
Make a pass on cold metal...then run a bead that half overlaps the first and you'll see what i mean. The last bead should always be flatter. It's the heat that helps it flow out.
Also...too much wire stickout will cause ropey welds..
I have tools I don't even know I own...
