FusionKing:
I didn't realize that MIG had that much control. For the OP, what filler would you use, 4043?

You gotta get the toes to wet out over the pores or you will have a perforated line around your work when ground to size. Then that could start a leak/crack in some cases (pun intended).
This is the OP's first MIG project and is why I joined the thread. Plus the frequent starts and stops. Funny pun.

Thanks for the detailed description. Spent my career at a desk , so I'm here to learn.
