My A81 torch got burned the very first time I used it, I did not like the burned look so I sanded the burned plastic flush with the brass. If the factory sold them flush with the brass, there would be no complaints. Now that it's sanded flush, there is no need to buy another cup. The burned cup just looked bad, it did not cut any different from when it was new.

My first cut was tapered, wider at the top than the bottom. It still cuts that way. The tip in the torch did not look all that good when I got it. Hopefully that will fix it.
