I have a speed-feed 400 on my ECHO trimmer. Any recommendation on what line I can use to clean up grass near concrete and lighting systems?

I try and pull out any grass or weeds around any exposted wires, or hit it with Total Vegetation killer.
As far as near concrete, you may be getting to close and using to high a speed so it's melting the line.
