Framebuilders - Welding Tip Sizes?

What size do you use for framebuilding? I got a set of tanks and a torch with cutting attachment for $25. I got the tanks filled and have found a place to buy some tips for this 40+ year old set. Just wondering what sizes I should buy. I'll mostly be fillet brazing for the purpose of building some trailers and cargo bikes.

It Depends.....I think most builders use the equivalent to Victor 0 to 2 size tips depending on exactly what they are doing and how long they have been doing it. The abilty to "be the flame"(R.S.) seems to affect the tip sizing choices that are made.

.035" and .050" would be good ones to have. A cutting torch is an entirely different animal. It has a valve and head system that allow one to start a burn through and then cut to oxygen only to complete the cut. You need an aircraft type torch, or larger format torch. Some of the old school builders used pretty hefty torches.

Thanks. It's an older victor J100 series torch. I've spent a lot of time using a cutting torch and I'm an above average mig welder. Fabrication isn't a new thing for me, but bike frames are.

around .035 seems to be popular . I used Mapp for many years and only went to O/A a couple of years ago. I found I like a bigger flame and low pressure so a Harris 6 has become my BFF (about .070)

At Trek we used oxy-propane with Gasflux and I preferred a big rosebud tip for everything except braze-ons. I could heat the joint quickly, flow the brass around smoothly and get out quickly with no charring or hot spots. With oxy-acetylene on my Smith's "Airline" torch I use an AW201 for braze-ons, and AW205 or AW207 for everything else.

I ordered a Victor 0 (.035) and 2 (.0465) tips. At $16 a piece I may end up ordering a larger one later.

Where did you find $16 tips?

Here is an online welding supply place I used to buy from when I was doing fab work on shifter karts a few years ago. They got harris/victor type for $14. http://www.weldingmart.com/Qstore/c000191.htm

They used to have 50/50 silver and flux too but I don't see it anymore

I have a little rosebud tip for the meco I am looking forward to trying on some lugs, seems to make sense.

jmichaeldesign,

The Victor J100 handle uses the same tips as the smaller Victor J-27, J-28, J-40 and J-50. You can also use Uniweld tips designated for both the CA550 and model 71 handles. These tips are also referred to as "Type 17". If you decide to swap fuels (say, from acetylene to propane or NG), then you'd be better served with either the UN-J or UNN-J mixer and buying the tiny screw-on 'TEN' series nozzles - this is what I use.
