We used to make gas fluxers out of the old AP steel cartridge oil filters. bubble the acetylene through a liquid flux and we used sifbronze rod from BOC - I remember getting some for Keith Averill so he could do repairs (20 yrs ago though), Dedicate a set of gas lines as you cant use them for regular work once you contaminate the inside with flux. The liquid flux is far superior to dip in or the serrated rods from eutectic. Makes you braze like an expert.............
I have a large commercial fluxer that I use that can be filled while hooked up - bit of overkill but really nice when you need it.....
If I could only work out how to rotate the image
