New 185dv owner with a porosity issue

[Deep Six]

Well it warmed up a little so I got back out there and practiced some more. Tried my new purple tungstens and new ER70S2 filler. Neither helped anything. Still getting that bad herringbone porosity.

I did, however, have some luck using stainless 308 filler on A36 steel. Does this look like everything is working right? The welds still look a little "frosted" to me compared to other tig welds I've seen...

Are you in DC or AC on this one? What is thickness and amps? Tungsten? Torch still in negative?
