Title: Cutting Torch Experience?
Post by: danwjmu on August 28, 2009, 03:52:04 PM
Has anyone used a gasoline cutting torch?  It seems to be a relatively new type of torch to the United States... mostly made and used by European countries and China.  oPetrol is a CDM torch...

Thoughts?

if you already got an oxy/acetylene setup, a cutting torch handle would be MUCH cheaper.  i would also tell you to take that money you'd spend on that particular cutting setup and spend it on the oxy/acetylene setup because its versatility.  it can cut and weld.  do what you like, or do what your told, we will all one day die.

remember, that's just the ebay price.  i'm confident you can find it cheaper on craigslist just because you can negotiate easier face to face.

What does a typical oxy set run for?  I most likely wouldn't be using it for any welding just cutting.


i've got an extra set hanging around my shop that has been used probably 4 times if you're interested in not paying retail.

the guys peddling that crap are assuming people cant afford acetylene (which is cheap as dirt)  and like shitty cuts.

One of the place's I used to work at, got suckered into buying a gasoline setup, it was nothing but headaches. If the gas sat for more then a couple days it just would gum up the torch and wouldn't cut right, even at the best of times it was a pain.

The shop literally spent months working with the manufacturer, and nearly $10k trying to get it to be reliable, in the end it was thrown in the trash, and they went back to acetylene / propane. Acetylene cuts faster as it is a hotter flame, doesn't take as much preheat to get it to the cutting part as well. Propane is a lot cheaper to run. So on same day rush jobs we used acetylene, on pieces especially thick ones we would use propane. One caveat is that this was all on a cnc burn table, none of this was free hand. In that shop all free hand was done by plasma, or oxy-acetylene.

dude i picked up my O/A setup for $90 on craigslist. this guy had it sitting around and never used it so he wanted it gone.
it came with 2 sets of regulators 2 cutting torches and a regular welding handle and tip. some stuff was victor some was craftsman. overall a few hundred bucks worth of stuff i got for under 100.

keep shopping you'll find treasure just like me. and my free bottle of helium is just another story. hahaha.

btw i moved into my new garage i should take pics of the new bottle.

We've got a oxy/accetaline setup and oxy/propane. The oxy/propane is what we use on just about everything. Cheap and works.

rested steel cuts just as well with oxy-fuel as fresh steel
the entire purpose of the oxy-fuel process is to rust the metal and blow it away. it works by rapidly oxidizing the metal.

look at the unsteadyness of both the operator and torch in the cut. those are NOT clean-cut! a clean cut is less than 1/8" varriance in the entire length of the cut with no wandering on the cutting flame.

operateor cant cut for shit, neither can that torch.
