Dual Tip Soldering Torches

Where can I get (or who still makes) the dual tip torches for soldering pipe joint? I saw one in use once and it looked like the perfect tool for the job; uniform heating and compact too.BJ

Becky Jane,

I have an old twin tip made by Prestolite which is used with a torch handle connected to a small acetylene bottle.
I find that for soft soldering copper tubing it applies the heat very quickly, making it easy to overheat the joint.

Really, unless you are using this for making a living and are proficient enough to get on and off the joint quickly, you would find a regular torch better.

I have a several different means of soldering at my disposal and my favorite is a Bernzomatic click start torch, using Mapp gas instead of propane..
The Mapp gas is a bit more expensive than propane but it is a bit hotter and the swirl combustion of the torch tip makes for a very short flame.
I use mine regularly and would be lost without it.

If you were to get one of these get the one with the flame control knob seen to the rh side of the handle.

With GregH: just why go that way . johnstone supply have them. Dual and wrapper tip. But I like a small oxy acetylene tip on what we call a aircraft torch very small gets in and get out. We do use a turbotoch with LP tank and also with prest-o-lite tank . Can use silfos15 on up to about 5/8 AC line and do a good job. Check out the turbotorch for sure I think its about the same as the picture that Greg has there

What we are up against is an older house that had rigid copper plumbing (and some soft) in 99% of it. Very few stop valves were put in at connections and now we are faced with redoing several things in some real tight spaces where a wiggle or wobble with a conventional long flame propane torch will equal a scorch on drywall or worse. The latest project involves replacing a freezeproof faucet that is through the exterior wall from under the kitchen sink. Have to desolder and change the Dr. Seuss looking mess that's in there now. We just need compact and easy to control flame that minimizes danger while applying the heat uniformly and precisely. Conventional propane torches just don't have it.BJ

With the double barrel turbotorch tip you would be on and off with Lp before you new it. It will solder up to 6" and braze up to 2"with LP.

Can also look around turbotorch have what they call amplifier shields that go on the tip and like hook around the other side of a pipe.

Becky Jane,

A dual tip will not make an unsafe solder job more safe.
I am not sure what tip you have seen but the dual tips I'm familiar with have a rather soft flame which tends to be long.
The shortest flame is with a swirl combustion tip of some type which the Burnzomatic is.
The absolute shortest flame I have come across is a Turbotorch A-2 tip but it goes with a set that uses acetylene.
Maybe Ed knows of something different.

I have considerable experience with dangerous soldering and brazing situations and it sometimes takes a great deal of ingenuity to make a set-up safe. A tip is not enough.
Pre-flooding the area with water, pre-soldering major sections and even using compression fittings if necessary.

I don't mean to preach but I've been in the trade for quite some time and have many recollections of fires caused by soldering and brazing.
Most recently by a handyman friend who burned down a small rental house he owned.
Because it was a commercial property the insurance company wouldn't pay.
Just for fun make sure you are covered by insurance for diy plumbing repairs.

Try and go to www.johnsupply.com They have the torches there the double barrel tip for MAPP and LP Look for #STK-11 . I think I missed it but dont know how you want to go MAPP, LP, Perst-O-lite or acetylene. I dont see the shields there, have to ask for them . They fit on the tips say they cut the soldering time by 40 % called Heat Amplifier Shields.

Im like Greg you should know what you are doing for sure.

ED keep a water hose by you all the time or go to Ferrules unions or just Flare fittings????
