By itself, it has often fused without creating wings, but the fuses are usually weak. They may hold 850 grams but break at 1050.
By itself, as long as I give to brief pushes as the process is starting and sometimes a sustained downward push too, the splicer has often fused without creating wings, but the fuses are usually weak. They may hold 850 grams but break at 1050.
Usually if all I do is push down the top ferrule and push the long fiber to the right at the beginning of fusing, the gripping clamps do not bottom out. They often move partway to the right but do not bottom out.

In retrospect, I probably only needed to rinse the filter screen. Next time I clean it that is what I want to do.

6/7: Jim explained what he thinks is happening with the lips. The cladding gets stretched as the wheel turns, and material gets caught between core and cladding. When the ferrules come together, the lip is pushed so that it sticks out beyond the end of the fiber, and the material between the cladding and the core also leaks out. These extrusions prevent adequate contact between the cores. The stretched cladding and extra material melt first between the fibers, so there is a smaller fused area, and the presence of cladding in the fuse weakens it.
We can try sandpaper or copier paper to remove the lips before fusing.
