you can buy a set for a wp17 torch off amazon pretty cheap.. https://www.amazon.com/TIG-Welding-Ceramic-Nozzle-Cup/dp/B0F9WNBX72? buying gass lenses on amazon can lead to some crap lenses that cause porosity.. https://www.amazon.com/RIVERWELD-Alumina-Nozzles-Ceramic-10N50/dp/B07XHKFMJ8? good for roots, tees and sockets.. you just need a standard gas collet holder, and watch the gas as they are smaller holes.. also note a 1/8" collet body can hold both a 1/8" and 3/32" tungsten with the correct collet.. i would suggest 3/32 for what you are welding. find ones thats most comfortable for how you weld, and wont stick, squeek, or chatter..
