would like to know what heat i should run welding flux core 0.35 and 0.45 wire in overhead and vertical positions on 3/8 to 1/2 inch plate.

you can get some pretty good settings at this link
http://www.millerwelds.com/resources/calculators/mig_flux_amperage_calculator.php
but make sure to use lower thickness settings for vertical than what is listed...
in other words, if you are looking for settings for 3/8" thick metal in the vertical position, select 1/4" on the weld calculator and you will be pretty close.
a resource for self shielded flux core settings is here...

you will need to copy and paste these links in your browser address box
best of luck to you
