I would like to add the following 3 points in favor of that these objects are not welding balls.
1. Their luminescence abrupt instantly.
2. All of them tends to move in the same direction towards a view.
3. There is no rest after their disappearance.
These are small specific ball lightnings. (see Physical nature of ball lightning. European PJ D vol.36, no.5, pp. 319-327. 2005)

Can you make some that fly at shoulder level?
Why do they fall down?

These were made by discharging high current low voltage DC through a silicon vapor. The silicon doping of the plasma probably gives it just enough weight to fall and bounce around.
Having one "fly" around at shoulder level seems unlikely. Shooting or propelling one is theoretically possible. The engineering behind such a task shouldnt be all too difficult (speaking in relative terms, of course.)
