also sometimes it works perfect than move over a foot and it will ball up?

OH and it does it on more vertical or inverted surfaces and not on horizontal that I can think of, such as where the gun would be below the weld. Also related to these situations, sometimes the weld will follow the wire up and and build a chimney around the wire.

Now given these are rare occurrence but when they happen they are a major pain so I would like to eliminate them and I havent found the magic bullet yet.
