Why are most self shielded flux core wires run on DCEN when most other wire feed processes are on DCEP?

Because they work good that way

Really...I figured it was the other way around. Either way if anyone has an actual scientific theory related comment I would appreciate.

Depends on the chemistry of the flux. Not all are run dcen

DCEN helps reduce spatter with self shielded wires.
