Require Small Torch

[Kenskip1]

OK so last week I was doing a muffler job on a Chevy Malibu.. Original exhaust system, 135K on it.Anyway I needed to heat a couple clamps but my bernzomatic propane torch just seems to take forever.Anyway my local Tractor Supply has this setup.BernzOmatic Cutting, Welding and Brazing Torch Kit. Has anyone used this rig? I do not have the resources for a full bore Oxy Acetylene setup.Just something that will heat and cut nuts off bolts or exhaust studs.Is this setup worth the cost or should I just go out and purchase a few more propane tanks?
While on this topic can I use the propane from a 25 pound propane tank for this setup?This would be more cost effective. Thanks Ken

At $11.00 each, the cost of the little oxygen bottles are your biggest operating cost, not the propane.

Find a used oxy/acetylene torch set, get a propane tip for it, since you already have a propane tank all you'll need is an oxygen tank.

You can heat, cut and braze with it, just can't weld.

Good usable cheap setup and bottle sizes can be compact if benefit on space/portability.

+2 for the small oxy/acet kit
The BernzOmatic kit is pretty much useless.....personal experience.

Map gas will burn hotter....not sure if that would be enough

get a plumber's acetylene turbo torch setup with a b tank. you can get tips ranging from about a 1/4" flame to a monster tip you can solder or braze with up to 4". we would get an adapter from the welding supply and use like a 100lb tank and they would last forever. with a 20' hose we never lifted the bottle

 

[CJM8515]

That kits worthless, I should know I own one. A small tank setup with a torch is a much better idea

 

[Kenskip1]

How about something like this? Anyone have experience with this manufacturer?

if you are talking about this thing...

No it won't work well, I have never able to cut anything with it, I don't know why they called it a cutting torch....... it does work to heat the nut, but no better than a mapp gas torch like the TS8000 except that it directs the heat a little better.... In short, no it doesn't really work that well... You might be wasting your $$$...


as far as using propane on those torches, they have that small appliance adapter in the HD/Lowes isles BBQ/gas grill area that you can buy... I have one.... but propane runs a little cooler and definitely not exactly for nut heating application... the oxygen is left hand thread, I have not seen one that you can use on bigger bottles.... maybe make one your self at your own risk...

These things..

But still that little torch is a POS probably for jewelers or something but definitely not for automotive or plumbing work. It does have some uses , just not this.

I thought that was discontinued years ago. All I see is Map pro which isn't the same. I bought one of those mini oxy act sets just for the OP's problem.

You need to get an aircraft style torch at a welding supply. That should handle all the smaller jobs like what you are talking about. Worked in welding supply and gases for years . I have a set and they are perfect for smaller jobs. Your local weld supply should still carry them. Or go ebay for a used set.

 

[Kenskip1]

Well so far I am striking out. What is the difference in acetylene hose and the hose for Propane. I have unlimited propane and am attempting to keep my costs to a minimum. Can I use the Acetylene hose with propane? Hazards?Ken

 

[plinker]

The only thing I've seen that's different about a propane set up is a different regulator & tip, same hose & torch.

 

[kelpaso1]

I use the same acy hose for propane. Hasn't been a problem. Now they do say to use a different hose for LP but.....

 

[kelpaso1]

I also have one of those cheapo torch/regulator kits and has worked fine for 20 years with propane. Just need to change the tip on the cutting torch but is readily available.

 

[RustyJunk]

If you want to use propane make sure you get a torch that will accept a propane/mapp tip because not all acetylene torches have that option.

 

[kctyphoon]

Try a map gas torch.. plumbers use them for the exact reasons you stated.. you can even get an extension hose to get the tips in smaller places.. its small, and light, and portable.. nothing to drag out..

Just posting the kit.. but pretty sure you can walk right into hd and buy the tank, a better tip, and an extension hose right off the shelf without buying the kit with the self igniting tip.

I’ve found the only good use for the bernzomatic kit was a fuel source for a large potato gun, otherwise useless.

 

[Kenskip1]

Well thanks for all the replies. I will pick up my new Lincoln Electric Oxygen Welding, Cutting and Brazing Kit tomorrow.I got tired of trying to piece all the fittings and what not, so I'll spend the extra coin and have a complete kit. I have a Lowes just down the road a piece.Tractor Supply has the filled tanks.Thanks again for your replies, Ken

Nah, then you just have to carry the tank into the house, and up stairs then downstairs, etc. I hate our torch, one van we have has a full setup with a b tank (Idk the size, heavy) and the other has just small map gas cans, both do the job and one of them I don't feel like is ripping my shoulder off as I lug it around. I've had great luck with the cheap benzomatic torches, surprised to see so many people hate them

 

[Finky198]

I have a Benzomatic TS8000 with a 4' hose that i run on propane. I use almost daily in the shop... yeah the little torches are slow, but they work fine for heating a nut or bolt although that's about the limit of them... I refill my own tanks as well...

I haven't bothered with map pro as the minimal heat diff vs propane
doesn't justify the substantial cost increase.

Is this the one you went with?

 

[Stuart in MN]

Might also consider a mini-ductor or similar induction bolt heater.

If he's on a budget, he's probably not going to spring for an induction heater that costs $400 or $500.

 

[Kenskip1]

Yes and the tanks (empty) are included.

Nice Let us know what you think after you give that puppy a spin or two

I've had my eye on it but haven't pulled the trigger...

 

[Kenskip1]

So with the tanks filled and all connections made it was time to light a flame. Now I want to make it public that I never had a torch.The closest thing was a bernzomatic that I have been using since Moses was here.I used the knowledge that I have witnessed on you tube.One flick of the striker and a flame magically appeared.Added oxygen and had a nice blue flame. Now with a 1/2 bolt in the vise I had the head cut off in record time.What a time saver.
Cost for exchanging cylinders, Acetylene $24.95 Oxygen, $19.95. I am glad that I purchased the set with tanks as they can be expensive.
Question,with full cylinders what should the pressures be? I set the pressures at 6 PSI, on the gas and 25 PSI on the oxygen.Thanks for the replies. Ken

 

[dogdog]

acetylene I have always learn is to not let it go above 15PSI or Kaboom baby...the regulator should have regulate that but hey you can always trust the regulator.....

Oxygen is what ever is needed to make that neutral flame or blue /oxidizing flame..

I always turn on the acetylene first then lite it and add oxygen to get the flame I wanted.....

but haven't used O/A for years

 

[sberry]

The O is set by thickness. See if it will make the cut turning it down 5 yet. For super quality cut you want just enough, for junk cutting a little more makes it easier.

RTFM. It's in the manual.

But the Lincoln/Harris stuff is decent in that you just set the gas pressures to whatever number the tip is.

Using a #2 tip? Set gas pressures to 2 psi.

#3 tip? Use 3 psi.

#5 tip? Use 5 psi.

Nice.

That's for the heating/brazing/welding tips.

The 6290 cutting tips are set differently.

That kit has the #1 6290 cutting tip IIRC. Set O2 pressure to 35-40 psi and Acetylene pressure to 5-15 psi.

And if you want to use a fuel gas other than acetylene, you need to get T-rated gas hose.

The 'standard' R-rated hose is for use ONLY with acetylene.

T-rated hose can be used with any fuel gas.

You'd also need to get the correct tips(s) for the fuel gas you will be using.

No, you really can't use a tip designed for use with acetylene and use it with propane.

And back to the original mention of the little Bernzomatic oxy-propane (or oxy/Map) torch. Within its limits, it works. It's fussy, and the oxygen cylinders are darn expensive for the amount of gas in them. I have heated, soldered, brazed, and oxy-cut with one.

The Lincoln/Harris is waaay 'better'.

MR, RTFM? Funny but my now filled tanks came without a manual. What I meant was with the tanks filled, how much pressure should be in the tanks?As of yesterday the oxygen tank was reading around 1800. I will have to check on the acetylene tank.Thanks,Ken

 

[MoonRise]

Ah, what is the cylinder pressure in a 'full' cylinder.

In that case, instead of RTFM you have to RTFC ("cylinder" instead of "manual").

Look at the top of the cylinder. There should be some markings on it which include something like

DOT 3 AA 2015

That is the DOT cylinder marking. The last bunch of numbers after the 3AA (which is a cylinder construction code) is the 'full' pressure rating.

In this example, the pressure rating of the cylinder is 2015 psi.

If there is a + near that marking, or by a date code reinspection marking, then that indicates that the cylinder is allowed to be filled 10% 'more'.

So a 3AA2015+ cylinder would be rated for 2216.5 psi.

Info vid:

Acetylene cylinders are filled by weight and not by pressure. Since the acetylene is dissolved (under pressure) in the acetone which is in the porous filling inside the acetylene cylinder.

I bought the Smith Little Torch It hooks up to my regular Oxy/Acetylene tanks.

MR, Sir your extensive use of the initials has me laughing. As mentioned that this is my first use of a set of torches. As you suggested to RTFM, my Kit did not have a manual. Just a paper written in about 5 different languages with type so small you required a magnifying glass..Anyway thanks for the information on the tanks. Much easier to read. BYW, i'm born and bread in the "Garden State" What exit? For me it was 72 I think... Forked River Thanks, Ken

You're going to butcher it. Take it to someone who actually DOES this and I don't mean MufferzB Us.or Moofla King. Find an old school muffler shop if you want it done cleanly and original as possible.Take $100 with you. It'll be less than what you'd piss away at torches R US( with free BernzAnothing baseball cap)
