What is making these little splatters on my TIG welds?
That is a 5/8" .049 wall 4130 tube on a 4140 bush, 1/16" tungsten, 1/16 ER70S-2 filler, about 10 l/min straight argon. I don't get it every weld:

I'm very much a n00b on the TIG & there's lots of things I know I can improve on like keeping a better torch position, balancing the heat better etc, but what it is that causes those splatters I don't know, & I want my welds to be purty dammit
Any other general critique welcome too.
