Has anyone seen this new cutting system. I just ran across it on craig's list and they have a utube video also. I'm impress need to go see if the welding guys got it. Oh the vendor is in Colorado Springs
Check it out.

yes i have one in my shop. its bin sitting their for about 8 months. it is pretty neat.... and does work but not to the extent that i wished ... so it sits till i get more time to play with it. the big sell for me was it oxidizes 100% or the metal so their is basicly no slag compared to an normal torch. the other thing (real reason for buying ) it should cut multipal layers of of stacked steel. it did do that but every now and again during cutting it would stop cutting a layer then start again. one of the neat things is it mixes the oxy and gasoline in the tip to the torch never gets as soon as you turn it off you can touch the tip. my boss went to the factory in California (but i think they have moved to colorado) and played with the hand torch, that he said worked really well. however we purchased a machine torch that we cant get to work as well as the hand torch he used. if you have any questions i will help if i can. i need to get it out and play again. their are little tricks ... if you wish to cut multipal layers you have to preheat all layers before cutting, so if you want to pears in the middle of a sheet and cut many layers you have to pears the first layer then preheat the second layer the preheat the third so on and so forth and bu that time the first sheet has a gaping molten hole that makes it useless. hope that rambling makes sense.

First let me point out I know little about this torch and I am NOT trying to down-play it since it may be the greatest thing to happen in years but I have a problem with some of the things the manufacturers are saying. First the Oxygen oxidizes the metal not the fuel, an Acetylene flame should be much hotter than gasoline and that thing about cutting multiple layers better just does not make sense. If you preheat every layer (which should be done regardless of the fuel) then it should not be any better than Oxy/Acetylene unless maybe the flame somehow puts the heat farther down the cut path which maybe it does. They also say that Acetylene can explode from shock or in the line without Oxygen I think maybe they must have failed a Chemistry class at some time, also they say Acetylene gas is invisible and only slightly odorless? Invisible yes but only slightly ODORLESS? They like to point out that Acetylene tips often only last a day while theirs last for years again this is simply misleading since if a tip is not abused it will last a LONG time with Acetylene and if it is abused then even the gasoline fuel is not going to save it. This is a few of the things I take exception to that they say and if you read closely some of the things they claim are quite misleading. As I said this may be the tool that will someday replace the Acetylene torch but when a manufacturer is that reckless with the truth and resorts to distortions and outright false "facts" I get a bit suspicious of anything they say.

Sorry I did not link the utube deal just do a search on utube. It reminds me of cutting with map gas. I just found it interesting a cheaper option. The vid does not show you how it works just a lot of cutting demo and expert saying how much you save and its been aproved for mining and some other area Yeah so what!
I would just like to play with one to see. The gas deal give me the creeps but it is a liquied vs a gas less chance to go boom! so they say.And I can fill up at any gas station! I don't know if we should let red neck have this power! HEHEHE!

What happens when it runs out and all you have left are the lines and container full of fuel vapor? They say it will not backflash because of the liquid fuel, which makes sense.. but running out concerns me..

[oldred]

Neither gas vapor nor Acetylene will backflash unless Oxygen is allowed to backflow into the fuel line which is why backflow valves should ALWAYS be installed no matter what kind of fuel you use.

[Rob Keller]

Gasoline or Acetylene
Explosion


If you are that close
Bend over & kiss yer asre goodbye
I fail to see the diff if you are on the business end of a torch.

As many ignorant dumb arses I see driving around with torches
UN secured
UN protected,
in Pick up trucks I am surprised you don't here about more explosions.

It might be a lot of things, but NEW is not one of them.

This system is VERY O2 hungry- it works at a 90:10 oxidiser:fuel ratio.

It does have its place in the greater scheme of things, though not likely ever gonna be in MY shop.
