Setting a diamond and welding it safe

This channel set diamond platinum eternity ring came to me with a diamond missing so I had to force back it's setting, set a new diamond in and weld platinum over it. This video shows all that, plus the cleaning up work and there is a photo of the finished job at the end.
The PUK 3S was set to 30% 6ms because it was platinum, if it was gold it would have been set to 25% 6ms because platinum usually needs more power to weld it. The diamond is very secure with the platinum welded over the edge and after filing/buffing then scorpering the inside edge, it matched the rest of the ring.
