flux core speed and amperage?

What is the proper speed and amperage for all positions on 1/4 to 3/4 inch plate while welding with 0.45 flux core?

mike,
unfortunately, there is not one setting that will work for all those applications.

I use this miller weld calculator a lot to get a starting point...

http://www.millerwelds.com/resources/calculators/mig_flux_amperage_calculator.php

just copy and paste the link in your browser.
the settings are pretty hot but they are intended for flat and horizontal welding.

but i have found this calculator to give me a really good starting point.

The best thing to do is to get the data sheet on the exact wire you are using.

good luck,

jody
