Welding dump truck bin

Hello Jody I just started working at this company that fabricates bins for dump trucks and they need me to weld the sides of the dump truck bin. The side is propped at about 70 degrees on a jig so that it can be squared of and welded. The process I use is a mig with .035 wire and about 27 or 28 volts at about 575 wire speed going down hill. I'm tired of grinding and getting very frustrated but my boss wants me to stay there. The steel we use is Hardox. They want a 3/8" weld. All your videos have helped me in the past so I'm hoping you can come through for me.
The steel is about 5/16" thick. And then there are the stifners that need to be welded which is another ball game all together. I've worked on flat welds mostly and a little horizontal but never downhill but I'm confident I can do this I'm missing the angle and control.
Thatnk you
