Well, thats easy, problem is that your using too long of a gun for the machine to push the wire through, so like "AAmetal master" said, use a single knurled 035 drive wheel.

Don't put much pressure on the drive and it'll work rather nicely. I see this problem in the field constantly, and this is how I fix it.
