True GMAW spray transfer simply will not go vertical up.  The puddle is just too fluid.

Your voltages are more toward the globular range which might go up but you will have difficulty with adequate sidewall fusion.

@ around 25 volts and 400 ipm your 0.035 ER70S-X will have a nice pinch effect and an open arc axial spray transfer. But this will only be effective in the flat and horizontal fillet positions.

You might want to think about FCAW and E71T-1.  You will have great fusion and nearly as good a deposition rate as spray GMAW and way better out of position deposition than pulsed GMAW.
