That's just st. Elmos fire! Dorks.. And its still bound to the laws of gravity where as ball lightning is not.

they are doing it outside in a driveway, you can see the stones and in the last 2 seconds can see grass at the edge of the driveway, and if there was no wind, then why is the smoke not just sitting on the object they're welding, its moving left, just like those molten metal spheres. and once they hit the ground, they are going down the incline of the driveway.

There must be some explanation that all luminous objects move forward and to the right the red glove. There is no wind in the room. But there is an inhomogeneity of the temperature because power suppliers behind the man and welding heat surrounding air. There is the gradient of air temperature in room. The objects move against the gradient. In the same direction must move ball lightnings (see European Physical journal D vol.36, no.5, pp. 319-327). Thus the objects are miniature ball lightnings

3 points testify that these objects are not welding balls.

1. Their luminescence abrupts instantly.

2. All of them tend to move in the same direction.

3. There is no rest after their disappearance.

These are small specific light ball or light bubbles (see Physical nature of ball lightning. EPJ D vol.36, no.5, pp. 319-327. 2005). They move along grad(n) where n is the refraction index of air in the room. That is why all of them fly in the same direction rather than in arbitrary sides.

looks like the small molten metal pieces that squirts all over the place when you're arc welding
