Practice with some scrap for your verticals..and again,,stay away from any wide weaving and whipping in and out of the puddle...bad habits are hard to break once you leanr them,and those are VERY bad habits...straight consistant beads are top quality and strongest ,run more stringers if you need more weld,wich means run a bunch of straight consistant beads along side the other untill fill completed.
The whipping in and out and any wide weaving is an automatic visual failure in any weld tests,especialy flux coated electrodes..for a GOOD reason.
Learn the correct way right off the bat and practice the BEST techniques and you'll never worry of your welding quality
Wide weaving and whipping in and out of the puddle is for beginners and bad habit creators who never get out of the habit to do it correctly and just cheat their way through it all..
it used to be a regular thing a few decades ago to wide weave and whip n dip,but in due time the research and expereinces with failed welds and slag inclusions have proven them to be failures in anything structural related...i know,because as a youngster i used to love doing it,but i finaly realised the right way after some coaching from older guys it was wrong and cheating,it takes a little practice to do nothing but stringers but once you learn it,it's easy and MUCH better.........
And that TheFabricator's link is clearly stating wide weaving and such is for 6010 rod..thats a rod designed for deep penetration and a fast freeze rod and recommended to whip n weave..but a very weak weld......7018 and fluxcore has a heavy slag..VERY bad idea to do any wide weaving and especialy whipping in and out of the puddle.....
Practice some verticles(uphill) welding on scraps...while welding,pay attention to the top of your puddle,,not underneath or behind the weld,but on the very top where you are burning into the base metal..you'll start seeing the difference of how the metal puddle and slag puddle reacts and start getting the "eye" for it the difference between the 2 and you'll start laying in some really nice welds...ignore the slag puddle that is falling off,pay attention to the fast freeze puddle.
You can also practice this with a peice laying flat,but on a slight uphill angle..this way the slag naturaly falls behind the puddle and you'll learn the difference between the 2..
