Gasoline welding

Unread postAuthor: frankrede » Sun Feb 25, 2007 1:01 am

Has anyone personally done it?
petrogen.com shows it being used to cut but it seems too good to be true, seeming that it can cut a lot better than acetylene there must be a downside to using it.

Based on what that site states, it appears that a downside would be the fact that you cant use it to weld. The highly oxidizing flame is extremely effective for cutting, but would turn the steel to an oxide without allowing any oppurtunity to fuse 2 steel parts.

True, for some reason I thought it could be used for welding but now that I look back to the site it doesn't.
Oh well. I think I'll still order one for cutting.

i think it would be a messy and inaccurate way of cutting and welding.even oxy/acetylene is messy, even with a skilled tradespersons isn't extremely acurate. stick to arc if you can this is not worth getting unless you are just cutting material to a basic shape not exact measurements.

The downsides are probably the things that professional welders are bothered about.

You'll still need to get yourself an oxygen tank but if its proven to work then why not?

If you really want to get down, and gritty with no regard to quality you can always cut with a arc welder. Although these are same people that don't care about quality, and when they weld with a MIG it looks like the backside of a porcupine. You know how hard it is to just get a wire to stick? You have to hold the gun like 4" away at least. While any person that has a brain can probably stitch down to .01".

So what are the advantages in this cutting torch? Its capability to cut thick material appears to be superb, but when in the hell are you going to need and cut 4" thick steel, even 1" at that? I do not particularly like a oxy-acetylene cutting torch because of its messy start up, and prone to failure during a cut. Even though a plasma torch is really nice, it distances itself in cost.

An Oxy-Acetylene torch would be the best bet. You can cut steel, braze, solder, and even weld with or without wire. It's more difficult than MIG, and in my opinion it's harder than arc also. But, once you get a little experience, you can actually make some pretty good looking, strong welds.
Oxy-propane works for cutting, and brazing. But, it won't work for welding steel. But, if you aren't going to weld steel, that would be a way to get out of having to buy an acetylene bottle and going through the hassle of getting it "filled" (I say "filled" since they just exchange them, has to do with the construction of the tank).

I'm weird, I know it, you don't need to tell me.

yeah acetylene bottles are built to reduce the amount of acetylene pressure, so they dissolve the acetylene in acetone and then soak cotton or some porous material (used to be asbestos) and stick it in the tank, So its faster and safer to just give you a new tank. Personnally I love oxy-acetylene, once you get the hang of it, its not that hard to cut weird shapes and strait lines (thought you usually have to smooth them with a grinder). But hey frank, get the oxy gas setup and tell us what its like.

Welding with oxy-acetylene is harder with out any benefit in my opinion.
It also can cause alot more distortion due to heat than mig or fluxcored wirefeed.
As for it being sloppy for cutting, I disagree. My friend pedro can cut real well with oxy-acetlyene and need minimal grinding/

Hmm... I think the air fuel combination in the fuel tank is kind of scary myself... What happens when you get down to the last bit of fuel in the tank, and the hose now has a mixture of air compressed at 100 PSI and Gasoline... That is about the conditions inside an engine when the spark ignites the mixture...

For my cutting, I use a cheap circular saw with an abrasive blade... Then you don't have to clean the edges when you're done, they are already straight and clean.

But you are limited on what you can do with a chop saw.
And their is no chance of explosion from the gasoline setup.
From what the site says it is perfectly safe/.

I'm sure the torch itself would have a back flow valve, as does every professional oxy/fuel welding/cutting setup.
