Periodic cleaning - at least once a year - seems to be a good thing to do.

We can see a layer of something on the risers that is starting to flake and curl near the burned area. Whether that is a layer of paint or a layer of dirt, that close to the brushes it will have a high carbon content. It looks as if several more risers may flash over soon unless they are cleaned.

So, the bare metal was due to welding? No arc there?

The arc you see is due to we repair the broken raisers.
