Basic 120v welder advice por favor

What do those little splatter balls mean? Some welds have more than others. But i kept the settings the same. So it must be mistakes in technique? Its possible the splatter welds had more stick out. I was afraid to touch the tip of the welder to the metal. One video said you can weld the gun right to the metal. 

 
My tip is brass, it might arc and may stick but I don't think it will permanent.  

The variation might be wind.  Or not as clean as the other spots.  Or slight waves in the metal that make for gap changes and distance variations or your hand sticking and bot sliding smoothly or you took your eye off of the puddle for a second to see where you were headed... 

 
Yeah i thought it would be strange for the tip to weld itself. Would expect that outter metal to be isolated? Its not my welder so i was extra extra careful. 

Got it floating!!! Next step will be playing around with bungee cords to support it driving down the road. I got 50 feet of 1/4" Marine grade shock cord. Plan to keep adding more and more loops until the tension is ballpark for the TV weight. 

That mount itself was just under 10lbs.

Too cold to start. Turn the heat up or feed down. You can always pull back a little as you weld and the heat starts to cause problems.
