For one off brazing jobs, like repairing a pipe i like my mapp torch, i have three different ones, i use a double burner one on bigger pipes. But for install, bigger pipes or component replacement such as driers, tev's, compressors etc you need an oxy fuel torch. Its not just the time to do the braze, but the time to carry the brazing torch from the van to where you are working that is a factor.
heavydiesel I’m looking for a set of back up torches in case I ever run out of oxygen or acetylene. What do you think is good for that? I used someone’s bernzomatic (I believe it was a bernzomatic) a while ago to switch out a compressor, he only brazes with that. I guess he doesn’t like dragging around the tanks. The first torch in this video looks pretty weak and like it would take a while when you’re in a hurry
I tried once brazing with maap gas on a 7/8 elbow fitting. I was up on a ladder about 20ft and shit let me tell you... I would not do it again. I gave up on the MAAP and went back down to get the B-Acytelyne tank. I had to rope it off the side of my ladder but it was just alot quicker. That flame on Braze-A-Gas sames really long. I wouldn't recommend using it in tight corners, especially if its a clients house. Learned that mistake :P
and what exactly is A gas suppose to be? some new magic gas like how they invented MAPP? it's obvious the first torch was fuel/air and the second was oxy/fuel which is hotter
@@a-gas8684 why chose music at all? it's not like we're in an elevator waiting for something to happen. why do you think you need music...don't have to reply just think about it. an explanatory voice, a real digital clock, a temperature gauge, something that provides a factual background. oh that's right 'you people' post some bs and think it's okay; first time I've seen the thumbs down rating is higher than the thumbs up..here's a tip. thumbs down buddy--maybe I'll edit this after I eat breakfast!
Not a damn thing was done wrong here. The puddle was "properly laid", the "silicon bronze 15% silver" brazing stick achieved a nice "plastic state", and flowed 'into, and onto' the joint , about as nice as I've ever seen - without going the "acetylene route". This work, without question, would easily stand up to the 750 psi required for a great deal of the refrigeration work done these days. About the nitrogen,,,,,,,,
mapp or map pro? and what is ''braze-a-gas''? No reference to it anywhere (google) other than this video and a site that sells refrigerant equipment -but makes no reference to this torch or gas -or whatever it is.
That's a real bad braze joint, with oxy acetylene it looks like wayy too much heat & all the braze flowed out, on the oxy acetylene you gotta learn how to control the heat man, a little practice & you'll get it man,that flame is wayy too big for that 5/8" pipe it looks like. With the mapp gas it looks like you did a good job, that's pretty much as good as it's going to get with mapp gas as the temperature of mapp gas is pretty low especially for brazing, for soldering mapp gas is good enough for sure
I’m no professional but watched my plumber do this under our sink and I have to say, whoever you’re guy is doing this, is terrible at it. If he’s not professional then he shouldn’t be doing a comparison video.
Your plumber was probably soldering with soft solder .... this is brazing its a more permanent bond and used on large diameter water supply copper pipes underground piping and heat piping .. this was a great demonstration
