MAPP gas torches

[voipio]

MAPP gas, and MAP-Pro are usable for brazing, but the part to be brazed needs to be surrounded with firebrick to keep the heat in.

So it's OK for brazing then? I have a maybe job that I could do with brazing. Does away with the fact I don't have a mill.

I've brazed with mapp. You can help it out by getting fire bricks round whatever it is you're brazing to reflect and keep the heat in the workpiece.

Edit: Voipio beat me to it.

OK, ta. Just got to learn how to braze now!

or use broken up grey soft breeze blocks packed round the job

Shop around for gas is the best I can say.

Last lot I bought [pre Bre*it iirc] was from Italy off an eBay seller. Import costs make them less competitive now I suspect.

if you have a Mapp torch, then it doesnt really matter which gas u use, because regular blow torch is 2x weaker than Mapp torch anyway?
but wonder what is the numbering standard of the euro gas tank valve outlet or smth? just 1/2" or something else?

There isn't anything particularly special about a MAPP gas torch, except that it is designed to fit onto MAPP gas cylinders and has a different sized gas jet. MAPP gas gives a higher flame temperature than propane, leading to faster heating times for certain brazing and heating jobs.

it sucks in more air because of its special design? atleast the one which is shaped like a gun's trigger(loop shape) in the bottom

Different jet and different nozzle, if you use a non mapp torch with mapp they burn out

And what happens to a MAPP torch flame when used on propane?

Never tried it if im honest, some of the modern torches are listed as universal but I only use mapp

I often use a blowtorch to redden up small bits of o1 or silver steel for little jobs. The blowtorch i use is a big old bullfinch, so i was considering buying a mapp torch from screwfix (the handiest shop ever, so close to me). I was going to buy this Bernzomatic one as its half the price of a Rothenburger. Anyone use one ?

You can pick up the rothenberger for about £60 online shipped.

I've got a Rothenberger I've had since the late '90's still going strong, including the igniter - well worth the money.

Other that the occasional bit of home plumbing, I mainly use it for heating up front crank bolts & steering tie rods

I've had that bernozomatic torch for a few years now. I use it for occasional soldering of pipework and big cable lugs, shrinking heatshrink, and generally heating stuck bolts etc. Plus of course setting fire to anything and everything I possibly can.

It has faired me well being thrown around in the Landrover and other vehicles and is still working fine.

Thats the one so. Thanks Dave.

I have the Benzo, it's been a workhorse for years, good quality

how did you get ones with a the valve on it and where does it get filled

if it has that loop in the bottom, then it should be better than the ones without the loop and 2x better than a regular propane torch:

both gases should still give the same exact temperature with the loop torch tho, so only the price should really matter
