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
