The torch model number is WH270FC-V.

 

For 3/8-3/4 a #2 tip is all you need. Rosebud is overkill.

 

rosebud will eat act. Do to Victor/s website for pressures. Your pressures seem too high.

 

I use a #15 rosebud with 5PSI acetylene and 40PSI oxygen. Tanks last long enough, although the company buys the tips and the gas!

 

You need to do some home work on your pressures. No offence meant here but your oxy pressure is way high for brazing. That is what you set the oxy if you are burning. A rosebud tip is for big pipe and copper to steel brazing. As stated above #1 and #2 tips are plenty. 5 psi acetylene and 5 psi oxy is what I use for 90% of my work. This comes straight out of the Harris book and the instructions that came with my rig. Some guys say 3-5 some even say 7 but the instructions say 5 and 5. Either way the pressures should be the same for brazing and soldering. Now if you are burning then 7 and 40 is the prefered setting. Again right out of the book. Setting your oxy that high makes no sense because you just regulate way down at the handle. Again no offence meant here. I know everybody has different settings they are use to. But if you read the directions that come with your rig or check a welders handbook you will see that your pressures are to high. Keep in mind that manufacturers differ slightly.

 

Thanks for the insight folks ! All input is appreciated.

 

Geez. I have a little mc tank with #15 rosebud. I crack my valves at torch and set act to 7 and oxy to 11. That is plenty enough. I was brazing 2-1/8 and using 45% on 2-5/8 with no problem.

A #2 tip set at 5/7 should be plenty

 

5 PSI acetylene and 7 PSI oxygen
Is this with the knob open or closed ?

 

I use a #2 tip and about 3-4# of AC and 20# of O2... works fine.

Raise the AC a little if you are doing a lot of 7/8, works a little faster.

 

Plus 1 for the 15 rosebud. And I really like the small NRP handle with Smith hoses. I do like the Smith handle and their rosebud is nice for smaller pipe.

 

Cool, I'm gonna lower my oxygen pressure.

 

I have a #15 and I had to call united refrigeration when I first got mine because it would stop working and be hotter than heck!! I found after they asked for me that my pressures were wrong. I wrote down on my gauges what settings are for #2, #15 and cutting torch incase I forgot again. lol I believe though my rosebud is 10 and 10 for settings.

 

Yeah, just old habit carried over from the cutting torch. I still like a rosebud on smaller pipe though.

 

I was taught 5/15. No. 2 tip. Seems to work well for residential stuff.

This works for me also. Upping O2 to 20PSI tends to make the valve on the torch barrel too sensitive.
