Some solder fell in the nozzle of my TS8000 torch and clogged things up. It wouldn't fall out, so I unscrewed it and pushed it out from the other end. Alas, not knowing anything, I also pushed out the what I'll call "swirler" out with it. I couldn't figure out how to reinstall it. I called Bernzomatic, because I couldn't see why one couldn't buy a new nozzle. Well, they sent me a new nozzle, gratis, with a nicely written handwritten message after a nice telephone call. I would call that excellent customer service.
