i used to use a lincoln harris brazing kit for about 7 years i always wanted a uniweld kit that had a good selection with different tips to choose from. so i finally got one. i was looking to keep a rosebud tip in my kit. i use to use my cutting tip without squeezing the lever as a rosebud type of tip. it worked great. but anyways has anyone used this tip before ? http://www.amazon.com/Uniweld-MTR-Mi.../dp/B00FI1JBFG
its the mtr micro 6000. i seen alot of people like the type 17-15 tip ive seen on other threads people say it can braze cap tube and up to 2 5/8" copper. the down side is that is uses alot of fuel. i rarely braze pipe that size so maybe i can tone it down to a smaller rosebud and save on fuel. looking for your input.

They do eat up fuel in that size, i have 3 diff ones that after a while it seems like thats all that i use. Unless you're fixing tube sheet leaks.

What size acetylene tanks are you using with this rosebud tip? I'm using a B-tank, should I be concerned with the 1/7th rule if my tank is getting low?

I'm using the regular small portable brazing kit. The one majority of us use. The tanks are a little over a foot long. I'll probably pick up the rose bud tip the little small one.

The acetylene is the mc tank and the oxygen is an r tank. I didn't know the name off the top of my head

I always have at least one rosebud handy. Having various size tips is the only correct way to go.

So probably the MC (motorcycle)tank rather than the B (bus) tank. I carry the B tank with my oxty and with the air/accet.

Be aware that that the safety recommendations on that webpage are limited in scope- for example it omits the rule of setting the bottle upright for an hour before use if it has been laying horizontal for any period of time. That's one of the very first rules I learned with Acetylene.
What lies behind us and what lies before us are small matters compared to what lies within us.

I have never worried if an acetylene bottle wasn't standing 100% straight up.

strictly speaking, that's not the rule.
Do you know WHY we are supposed to leave them upright though?

If it is unsafe to withdraw more than 1/7th of the cylinder contents per hour, does that mean with a MC Tank (10 cu.ft) I cannot use a tip that consumes more than 1.42 CFH? And with a B Tank (40 cu.ft.), 5.71 CFH? How is this true? I've used a A-32 Tip (33.2 CFH consumption) plenty of times with my B Tank, no problems.
