Default Re: Not plating along edges?? whats wrong

Sounds to me like too much current to begin with. The dark gray is evidence of burning.

3" x 1.5" x 2-sides is 9 sq-in, @.14 ASI gives 1.26 amps. Why did you choose 1.6?

The edges of large flat pieces are higher current density areas, so get more of it to begin with.
