I agree with Chevy and Mikey it sounds from your description that the wire is not feeding fast enough or erratically. When you pulled the wire through did it come through easily and smoothly? A bad tip is a simple but extremely common cause of this problem so is it new? Like Chevy suggested check the drive rollers and make sure they are right ones for this wire, also have someone else watch the rollers while you are trying to weld and make sure they are running smoothly.
