Welding Tips and Tricks

As someone who plans on living in Australia I reckon I better learn how to do open root with 7016s since I heard the majority of open roots with stick is done by them. So, how is this done? What are the settings when 3/32 (2.5mm) rods are used? Does it matter whether DCEN or DCEP is used? Is there are keyhole? Can you push that rod in like you would with 6010s/6011s? Is the "kwoosh" sound similar to the one that's made by the cellulose rods? Thanks in advance.

Come on... There's gotta be at least a couple of people on this forum that knows how to do this. Btw, any tips for 4g open root with 7016s? Do you just push up against the bevel a lot harder than you would with the other positions? Thanks in advance.
