Which torch is hotter and/or faster, both using Mapp Pro gas 
Хобби
I went out and got the TS4000 self-start nozzle with a bottle of MapPro today and it enabled me to finish a brazing job that I was unable to finish with the Propane bottle and standard nozzle. Yay!
Much hotter on the map pro 3730 deg, propane in the right part of the flame 3596 , glad you were able to get your project done
Thanks for doing this. I'm not a welder but I need to make some 12 inch long M5 bolts, so I need to braze an unplated nut to one end of an unplated threaded rod. I figure I'll screw on the nut a half inch onto the rod, braze it, then cut off the excess rod, belt sand the bronze flat, so in the end I have a very long bolt with a nice hex head for a socket wrench. I'm hoping this will work. These homemade bolts wont be torqued very tight in use but are surely cheaper than paying $12 each for extra long M5 bolts (If I could even find them in the USA). Thanks again for teaching me how to braze!
Afternoon, high tensile strength when done correctly, 60,000 psi is average tensile with the correct heating and filler rod. A lot of times the weld is stronger than the base metals. Watch the other brazing vid I have with the oxy rig to watch the color when to add the rod/flux. Bright orange, test on some scrap then beat the hell out of it to test. pre heating is the key, no cool spots were the weld is ...best of luck
Thanks good work...i have idia how to wilding.copper to braz
Nice video, fuel consumption is also something worth doing a review.
Weight the tanks before each run to determine fuel consumption ? If one is faster it may be burning fuel faster. Well done video , very informative.
hi Joe this was more about the heat from each torch due tot he different nozzles but if I do another with a large time on larger heat requirement it may be worth getting the scales out. have a good day regards Dave
@@dctmakes3487 Nice video , I always wondered about the turbo nozzle difference. Well shot and laid out.
At full output burn . TS8000 burn twice as much propane per minute compare to the TS4000 .
But most of the time TS 8000 also heat in half the time .
Great video am thinking of getting the ts 8000 , what rods are you using would they have to be 1/8 rods and what Flux can you use pre fluxed rods any help would be appreciated. Also could you braze your car exhaust with it .Thanks Dale
Morning, I use 1/8 and 3/32 bare rod bronze with Hobart flux. Also Lincoln flux coated rods of the same two sizes. here's a list www.northerntool.com/shop/tools/product_200659237_200659237

You can braze exhaust pipe but you have to have clean metal and control the heat well, warm the joint all over then hone in to do the color watch to know when the bronze will melt/flow. watch my other vids with the oxy torch to see the color point, then as the bronze flows to the joint move the heat around the joint. If you don't the bronze will just sluff off . Ya dad said what I am going to say next ............ practice on the same metal thickness and shape if possible. best of luck
Grazie,
What's the difference between brazing with bronze and brass? I watched a guy weld broken cylinder head fins on a cast iron head using brass. I don't understand why he chose brass over other metals. He was also using an acetylene torch. Does brass require higher temperatures? Could you do the same repair using bronze with mapp gas? Thanks for any input.....
Hi, yellow and red brass have a slightly higher melting point than bronze rod. Different cost also, both are not actually melting the base metal just using capillary action gripping the surfaces. around the same strength psi Lots of things affect this though, surface prep, porosity etc. endless list . main thing bronze is corrosion resistant to lots of different conditions and brass is more easily shaped/cut and more malleable. the mapp torch will not create the same volume of overall heat on a larger piece than a oxy rig. small area sure you can braze with either.. but this barley covers brazing possibilities, have a good day
Would the ts8000 be able to braze 4mm moderate steel?
I don’t know if i need a different torch, gas, or brazing rod. I just searched and tried to find something, but it didn’t work just now. Heated the metal forever. It is -2 C in my shop though.
Perhaps i need every variable changed.
Evening, yes but MAPP PRO gas not propane and make sure the joints are clean. Watch the heat color on the videos for the bronze to be introduced (not too early) practice if possible on some scrap if you have it. Suggest 3/32 bronze bare rod with Hobart flux , The Mapp gas burns way hotter
You might try the same tests holding the torch an inch farther from the workd.
yeah I hear ya, trying to explain flame density, heat draw and all the other detail in a short vid was not the intention, just some neighbor's saw some vids on brazing and they came and asked about it, they did not believe you could braze bronze with Map Pro. May be I will do a vid with more detail
What composition brazing rod did you use? What portion of it is silver (Ag)? DOes it contain Zinc (Zn)? What is its melting temperature?
straight copper/tin alloy .... just over 1600 F melting point
@dctmakes3487 This is very high temperature, melting point-very impressive performance. With silver rod that would be easier.
@@eugeneeugene3313 sure but not as strong, 63000 psi on a good braze with that bronze
@@dctmakes3487 Do you mean 63000 psi for your copper/tin alloy or silver alloy? I am contemplating between Stella Copper-Phosphorus-(Silver) Alloys without Zn, like Ag15CuP and the Zn-containing alloys, Ag30Sn. Ag15CuP claims tensile strength 54kg/mm2 (76806 PSI) and the Ag30Sn 48kg/mm2 (68272 PSI). What do you think?
@@eugeneeugene3313 no expert but would depend on the project requirement the stronger braze may be more brittle. probably better to contact the rod manf. based on the actual project requirements, sorry no specific answer. hope ya find the info
thanks for the useful video, what did you use for flux?
Thanks!
Hi, its HOBART brazing flux from places like Tractor supply, Northern tool. I think amazon has it also
@@dctmakes3487 thanks!
They have brazing Flux, obtainable at hardwares! Borax dry laundry soap !
Good day... I'm from philliphine.. where can i buy that wilding ..
Amazon Prime
or are you looking for the bronze rod >?
Will the torch work with flux coated rods?
Morning, yes it works with coated rods just a small amount more time on the rod to initiate the melt
@@dctmakes3487 Thank You!...Happy Thanksgiving to you and your family!
Of course it will !
Can mapp gas braze thin cast iron?
you can but on the smaller side as the metal acts like a heat sink, and the torches dont have the BTU to keep the right amount of heat on a large piece of cast iron
@@dctmakes3487 I have a 2nd propane torch to help keep the surrounding area hot. Thank you this answered my concerns if it was possible at all
Hello dctmakes.....................are you able to instruct me how to "debraze" steel parts? Thank you
Depends on the thickness of the joint, if its thin you heat it to molten and very carefully pull the joint apart being really careful of molten weld substance, wear gloves, glasses, leather apron and do it at your own risk ...always dangerous pulling molten joints apart
@@dctmakes3487I thank you for the response. Never have done so before Safety safety safety goes without saying
Complimenti, il migliore quale e? Grazie
TS8000
A high-tech product was born, a high-temperature flame welder that uses air instead of oxygen acetylene. Looking for partners worldwide!
Very brazen of you to try that!
ROFL
😅😂🤣
I just had to! Yeah yeah, I know... too easy.
Is that flame a bit close,
It is, I was going for equal not trying to explain flame density and heat range in the flame column, imagine the questions if it was further away and you could not see the blue flame
