I wonder if a magnetic pulse, or a
pulse wave is involved in the operation.<

Jones,
I am now coming to this same conclusion, thermal transfer rates from 5 PLC heaters spread throughout 1 liter of powder doesn't seem fast enough. ........


I had the feeling that the heating was by directly passing the current through the metal bed - that would make for very fast transfer.
