Hi. I am aware that there are three types of Victor torch handles, the Performer (J series), the Super Range (100 series) and the Journeyman (315 series). I saw a post that said that you could use 100 series tips on the J series (aircraft type?) handles for less fatigue for small hands. Are the threads for all these sizes compatible? The largest one (315 series) looks like it has a larger threaded coupling, but it is hard to tell from pictures on the WWW. My local store only carries Harris and they know little about Victor.
Thanks, Eric
