Please convert to english standard measurements. Correct me if I am wrong, You are welding 3/8" plate
Using 30 degree bevel
with a 1/16"+ land
with a 3/32" Gap
with 1/8" E-7018 rod

What seems to be the problem?
My conversion is likely way off, but I have done this proceedure (sucessfully) with 3/8" plate,
using a 37 1/2" included angle
with a "nickel" land
with a 3/32" Gap
with 3/32" E-7018 rod set around 80 Amps (DCRP)
The plate was in the vertical position.
You need to describe(in detail) what issues you are having in order to get a useful response.
