Vortex MAP Brazing Torch with Brazing demonstration

Vortex Map Brazing Torch Unboxing and Brazing
This video is long to show in real time how long it takes to heat steel up to a high enough temperature to braze with SIF Bronze No 1 brazing rods which melt at 900C but flow freely at 950 to 1000.

That was an excellent demo for any one wanting to learn brazing Ben. I was looking online for a MAPP torch and some of them are priced 20--40 Pounds which seems at first quite reasonsble.However after watching you demo it becomes obvious that they only have just one torch ! The model you demonstrated seems very good and shows us the limits before oxy-acetylene is needed.Thankyou for your time .I'VE learned a lot

[@BensWorkshop]

You are very welcome. Many than for watching!

Hello Ben, A nice bit of kit... and worked well... good video, thank you. Take care. Paul,,

Many thanks Paul and thanks for watching!

Hello Ben, nice video, try putting a fire brick each side of the workpiece make a roof with one as well if possible, that should help to get up to temperature and save on gas as well.

[@BensWorkshop]

A well made point, that is however all I have in my shed right now but I can go and get some more. Many thanks for watching!

[@MrFactotum]

eyup ben winner winner, chicken dinner, great torch, can i hear the distant rumblings of a Loco boiler on it's way!! cheers Kev

[@BensWorkshop]

Soon I will be doing some small boilers, then building up to a boiler for a part built loco I bought with original drawings. (As in the hand drawn ones by the chap making the engine who designed it as well). After that I may well make a loco or two. That said, the paraffin blowtorches are more than hot enough for silver solder. Many thanks for watching!

[@AliMackMechanical]

It's map gas I use all the time when am trying to remove old Seazed bolts.👍

[@BensWorkshop]

Yes, I use a small propane torch for the job though as that is what I had though it doesn't get hot enough for brazing. Many thanks for watching!

[@GrumpyTim]

No wonder I've failed in the past, trying to braze using a combination of normal gas torches and paraffin lamps - that Vortex torch and gas combi packs quite a punch!!! You beat me too it, suggesting that you could have maybe done a bit of pre heating with paraffin first, although you'd then have had two torches on the go, and you don't really want one unattended while you carry on with the second, just in case something unexpected happens. Those huge paraffin torches like you and I both have were technically sold as a brazing torch according to an old advert I found, but maybe they were doing stuff like sheet metal or small items, because the chunk of steel you were working on was just eating the heat. Obviously oxy acetylene is the best choice, but the bottle rental costs are phenomenal, and just not viable for occasional home use. Great video Ben, I might try some brazing of thin stuff using the massive ex MOD torch - must gat some flux first, I've got the brazing rods - been there for years........

[@BensWorkshop]

Brazing flux is cheap, got mine from here. www.weldingdirect.co.uk/General-Purpose-Brazing-Flux-Powder I suspect that if I built the hearth around it better it would work better. Many thanks for watching!

@@BensWorkshop cool, ta, I'll check that out. I think I did like the video before I added the comment - I'm sure I did! but in my defence a member of the household brought us the gift of Covid and that thing they say about brain fog is definitely true!!!! Been trying to work on a video and it's been like a disaster movie - I did 185 takes trying to record the voice over, and that was just for the second half of the video!!!

[@BensWorkshop]

That's a lot of takes. I only ever do one and without a script.

[@BensWorkshop]

Hope you get well soon, and I see the issue, I was looking at the like count on my latest video, this is a comment on the previous one. Vitamin C and D will help you recover quicker.

[@mr1pearl]

Wow that map gas does work but it seems like you are using a lot of it ?

[@BensWorkshop]

Yes and yes. Would have been an idea to preheat with one of my cheaper blow torches. They are mainly meant for plumbing and HVAC industry where you are working with copper pipe. For plumbing the solder also melts at a much lower temperature. Many thanks for watching!

[@GuysPlayingWithTools]

That was interesting. How well does it stand up compared to an arc weld? I have been thinking about learning assorted welding techniques and am starting with arc welding and moving on from there.

[@BensWorkshop]

It has the advantage of being able to solder different metals together like brass or bronze to copper. Also allows you to join metals that you can't weld as long as the base metals have a higher melting point than the solder. However welding is good and starting with arc is also good. Go get some scrap steel from the scrap yard and practice.

[@BensWorkshop]

Forgot to say many thanks for watching!

[@GuysPlayingWithTools]

@@BensWorkshop We think alike. I always have something lying around that isn't going back together, I will practice on that type of stuff. I got a cheap(sort of)adjustable 225 amp welder to learn on.

[@GuysPlayingWithTools]

@@BensWorkshop 😅 I knew that

[@BensWorkshop]

Is it an inverter welder with anti stick? If so, should be easy. Also have you got an auto dark helmet? I can post a couple of quick short tutorials if it helps.

[@rinklestiltskin]

That is a heavy piece of steel, and in normal practice it would be welded. It does prove that lighter stuff more suitable for brazing can be done easily.

[@BensWorkshop]

What you would use to join two bits of metal would depend on what sort of metals you are joining, you can't weld dissimilar metals, or example brass or copper to steel, so it would depend on what you are joining. Also there may be other reasons for soldering, for example considerations of either distortion or shrinkage which are a bigger problem welding that soldering.

[@rinklestiltskin]

A colleague frequently welds stainless to ordinary steel with a mig welder and non-stainless wire! None has ever failed to my amazement. I was apprenticed so long ago we were welding by hammering hot iron together !@@BensWorkshop

[@BensWorkshop]

Yes, I am aware people do that and have seen it on KZbin, but I am not aware of anyone welding brass to steel...
