In my opinion, that is melting caused by fire impingement.
To be fair, it could have been arc melting at one point in time prior to the external fire impingement.
You may want to search for the ATF Technical Bulletin 001, which looked at the characteristics of arc melting and fire melting discussed in 921. The forum won't let me post a PDF, but the document is freely available.
