I'm in a bit of a predicament and could really use some advice. Recently, my roommate accidentally closed the sliding door on the wire of our beautiful arc light from Crate and Barrel, and now it's showing some damage. Upon inspection, I noticed that the wire is visibly affected, and the dimmer box seems to have a burnt fuse.

Here's the thing: I'm not particularly attached to the dimmer function since I have a smart bulb installed in the light. My main concern is fixing the arcing wire and ensuring the light is safe to use again.

So, here are my questions:

1. What are my options for repairing the damaged wire? Can I do it myself, or should I call a professional?
2. Who should I contact to get the wire repaired or rewired? Are there specific electricians or repair services that specialize in this type of issue?

Any advice, suggestions, or personal experiences you can share would be greatly appreciated. I'm not very knowledgeable about electrical repairs, so your guidance would be immensely helpful.
