Five pages! Might as well keep it going :)
Here's a tip to add to the confusion.
Try a stop start pattern. It's much easier than a running bead. Use a high amp setting for good penetration and just put blob on blob. Pause enough to prevent burning through, usually just a second or so.
This method allows you to really see the puddle. It is much harder to see the puddle with a continuous arc.
Your pics show you are not seeing it well. Lighting and helmet setting are important. Focus HARD on that puddle.
Once you are seeing the puddle better, you will have more success with a continuous bead.
Others I've shared this with have had immediate results.
