When there's slag, you drag. With stick and flux core, you drag away from the puddle. It's basically using the arc to help keep the slag pushed back to lessen the chances of having slag inclusions.I am still a bit fuzzy on the definitions of Push and Pull that I hear folks talking about but I weld MIG just like I do stick with the electrode pointing toward the puddle and pulling the torch back down the groove.
With MIG, you push with the arc going into the base metal with the puddle trailing. My uncle says it should be more of a back and forth motion. Base metal, backstep into the puddle, base metal, backstep into the puddle. I assumed it was to help with penetration. I don't have a gas bottle yet, so I have yet to try it on my own. The friend that gave me the scraps let me use the MIG welder at his job on one of his projects once.
I can honestly say a 480V welder doesn't have any problems with fusion. I didn't really get to enjoy it though. The feed speed was so high, as quick as I started a weld it was over. They had it loaded with .045, and he said they use that 1 size on everything. I've gotten 12 gauge sheet up to 1/4" angle from their scrap bin.
