I have found that the straight MIG using gas, does have dingle berries... I talked with a fellow that owns a W-Iron shop, they build gates, etc. he said what they do to end that problem is soak the whole roll of wire with WD40, and he said it takes a whole can to soak it good/right, then there is no sticking of the dingle berries. I found that works good for me also... Plus I use a rag, soaked with WD40 held into the wire with a wood clothes hanger/clip, just before it enters the tube shaft... This helps with keeping it oiled up good also, I spray it everyday... saves a lot of clean-up time.
