doug fattic;9916281 They work okay but not as well as my Victor J-28 and Uniweld 71 torch handle with a UN-J mixer and elbow with TEN tips attached. These are propane specific tips. The same mixer/elbow can accept TE tips designed for acetylene. The short recessed hole on the end of the propane tips help keep the flame from detaching. [/QUOTE said:Doug,
good info in that post, thanks. Do you have an online source for the UN-J mixer and tips, or do you buy yours from your LWS?
I've wanted to try Propane for some time. The screw in tip set up seems like a good way to go for experimenting with this.
The three sizes of Victor tips I use with propane are the #2, #3 and #4. The #3 is most commonly used for brazing lugs and the like. The #4 would be for heavier stuff like bottom brackets and the #2 for braze-ons. Personal preference may want to take it down a size. If one is skilled they may want even larger tips. I don't have an opinion on the size of a rosebud for propane use since I seldom use them and if I do it is with acetylene.OK Doug I ended up with a uniweld 71 handle so I will get the victor un-j mixer and some TEN tips. Which of the TEN tip sizes do I need to cover typical bike work? (a #1, #2, and #3 ?) Also want to get one of the TEMFN rosebuds and they come in 3 sizes - guessing the #4 should be OK?
