You get more gas to surround your weld. It was Ben that told me about the resistance. The wire gets hot, of course, and is deposited in the puddle. But, you can keep the puddle more in control if you're not loosing a lot of heat to an electrode that is out of the puddle. Angle has a lot to do with it as well.
That may not be how the welding engineers explain it, but that's what I gather reading about it.
