I'm going to give you a general statement or two, since exact setting results may vary. Pulse MIG is designed to operate by primarily spray arc, but to dip into the globular transfer range long enough to cool the weld but not transfer any metal. Using the basic setup you'll probably push every ounce of power out of the unit to get marginal results at the results you have posted in regular mode. Anything you do will cause the weld to weld cooler so, creating a too big of differential in amps will create issues.
