"80% cheaper then O/A cutting"

admin

Has anyone used this cutting system yet?They say its 80% cheaper that O/A cutting..From hacking up things in the back yard to demo use, it sounds ok. This one is made overseas, I wounder if I could find a cutting system like this Made in America? http://cgi.ebay.com/ZH-Oxy-gasoline-...-/400130509022Classic 1D 200SAE 30086 SA 200Hyperthem 45Jancy Mag Force O/A Victor-GossCable's remote2-12" Mathey Dearman bevelersLN 25Miller Auto Set 211Wendy's Pancake/Jackson PipelinerNew Holland LS 180Great story man....tell it again!

Reply:how can it be 80% cheaper? You still have to have an oxygen tank and regulator. So for $395.29 + $200.00 shipping you have the torch, gas tank, and hoses. For $600 you can get a nice O/A torch. I understand about gasoline not costing as much as Acy but the O/A setup has been proven to be safe over the years. Given the fact that you use your head with it. I personally like this part of the description. 1. It is safer than acetylene and the other gas. Non-tempering, non-detonating. The fuel tank adopts the advanced explosion-proof device so that it can reduce the explosion probability to 0. It is impossible to explore even if the fuel tank contacts with the high temperature and open fire or to weld up the damaged fuel tank with gasoline. The cutting torch adopts several unique technology of “ZhongHuan”. When the oil tank is in the circumstances of non-pressure, the cutting torch can keep on burning but not tempering when it is in water.Appaerently you can weld on this tank full of gasoline without it exploding... Not trying to be an *** but WHAT IS YOUR LIFE WORTH??? That's just how I look at it.LukeMillerMatic 212Mkita chop sawand a head full of ideas

Reply:Someone can correct me if I am wrong, but doesn't acetylene burn hotter than either propane or gasoline? Should make for a better cutting tool in that regard.I've heard of these oxygen/gasoline torches before but have always been cautious to due the same safety considerations mentioned above.Andrew

Reply:doesn't acetylene burn hotter
Reply:Here's another angleI purge my lines on my cutting rig.  A small volume of acetylene is released into the atmosphere, and fairly safe when done outside.How on God's Green Earth do you purge a line filled with gasoline without all sorts of precautions.  A puddle of gas is infinitely more dangerous than a bit of acetylene which starts to dissipate almost immediately.Let's say you don't purge your lines.  Cut a line filled with acetylene, regulator shut down, and all you have is again a small amount of gas in the air.  Try that with gasoline.The surge protector thingy might be just fine, but again a ruptured line means gasoline all over the placeAnd what's the rupture resistance on these wonderful new marvels of modern science?  Will the gas tank stand up to the impact that an acetylene tank will??I wouldn't have one on my place."Any day above ground is a good day"http://www.farmersamm.com/
Reply:There is a contractor here in town that uses petrogen torches for repairing rail cars. Says he loves them. Cuts insanely thick stuff too.

Reply:I used one of the petrogen torches back in the 80's scrapping. Its based on the same technolgy as a coleman stove.  If I remeber right a gallon of gas would last for ever. you could blast thru some wildly thick stuff but they had huge tips in them.
Reply:I don't see any up-side, just big down-sides. I watched the videos.Some of the cutting torches don't seem to have an O2 lever? A twin-hose is tough to keep untangled, the separate hose jobs must be a mess.They give a quick lesson on how to weld a gasoline can, while full of gas:And what's with the bloke waving a lit torch around a room full of combustibles, that looks like a hotel room?

Reply:We had one of the petrogen torches for demo work.  Most of the time the O/A torches got used however. they were just more versitile.  I see big issues with things like tips with that cheap knock off. I've seen enough Victor clones that won't take standard tips simply because the tolerances wouldn't match, to see big problems down the road with consumables..No government ever voluntarily reduces itself in size.

Reply:I work for the Fire Dept and we use Petrogen and O/A. You can cut with both but you can weld, heat, braze and cut with O/A. I dont know that its all that cheaper to use for cutting. It goes through gas pretty quick. If the price of gas keeps going up, I might need to run my car on acetylene.
Reply:Well, it would be good to see some proffesional safety and performance test for this product. If it prooves safe, it might be worth a try. Like someone already said, O/A has its potential safety problems. I've seen a few O/A mishaps.

Reply:i have the pieces for that type. been so long dont remember why i quit using it. hoses are bad now. it did work but i think it was slow. that was in the 70s so this old mans memory aint to good. think i went back to O/A because it was easier and less hassle.

Reply:Yeaaaahh!!!:
Reply:LOL! I've used those old pump-up gasoline/oxy torches before. They are nothing new thats for sure. Worked on a job for American Bridge Co. and you get a chance to work with all kinds of antique tools. They are more trouble than they are worth is my impression of them. First, it doesn't take long before you have to pump the tank plunger again if making heavy cuts, then you also don't want to be stuck in a confined space with the rig because of the constant drip-drip of lit gasoline falling from the torch tip.  They will get the job done I suppose, but they are messy and for those areas like demo where flames/sparks/fire is no biggy. Maybe a brand new set up will perform more favorably I don't know. Good luck
Reply:The FD here has a similar system on their heavy rescue rig, except that it burns diesel. If you are interested, look into it. liquid gas is different than acetylene gas, so figure out how to deal with that safely. Being able to fill up at the pump certainly is appealing.A torch is a torch. We use different fuels all the time on the job - propane, propylene, acetylene - whatever is available. Each of those has advantages and disses. I suspect that this would too.Weldanpower 225 G7Ironworkers Local #24

Reply:Originally Posted by denrepGood that pumping gas is a appealing, because the gasoline torch requires frequent trips to the pump.Good Luck
Reply:Originally Posted by tenpinsI cant count how many times we've run out of acetylene on the job, but the store was closed or when we worked weekends, and the store were closed. Some spots in these mountains, the store is 50-100 miles away, and they only deliver once a week. . . .

Reply:Acetylene is much more volatile than petro.  You don't see mist being sprayed all over a gas station while filling vehicles.  Acetylene is not even fillable at the LWS because of SAFETY and DANGER.  The real problem is using something that is not the norm.  We are creatures of habit.  If danger is the escape goat then no complaints against the diesel set up.  They are just so dang expensive!  Not many folks weld w/ O/A anymore anyhow.I guess it would be like showing up to a pipeline job with a Miller!  In the end I currently own O/A, but have a petrogen on the toys list... maybe someday... probably not though.The above link has really good info and dialogue... just finished reading.Last edited by six; 04-04-2011 at 12:45 PM.
Reply:*newb entering the room*I like the idea of being able to use the same setup for cutting or welding ... If you can't weld with it then you are gonna have to get a separate setup ... That means more money ... If you are gonna do both then get something that does both ... Costs less ...I have been there, done that ...

Reply:Just got one three months ago.  Took a couple weeks to get used to speed and flame adjustment.  Flame adjustment much diff. then o/a propane.  Once I got the hang of that it was a walk in the park.  Burnt up about four tips in the first two weeks which are not cheap.  Biggest learning curve when cutting is that after ignition u should back tip of steel 3/4-1inch away from steel.  Sounds crazy but works.  If I did that with an o/a i would lose my cut. Three months and I have made my money back in fuel savings alone.Just talked to these guys yesterday. ordered an air pressure regulatorso I dont have to ever pumpthe tank up.  Guy said there gettin ready to release a new system that runs off a variety of liquid fuels that outperform gasoline and are less volitile like kerosene, diesal,biodiesal, and some kind of military fuel started with a j or somthing
Reply:Bloody hell, for the price of a tip I can do everything Petrogen claims and then some with Propane/Propylene with any of my torches.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:I understand you are a master at our craft. And I respect that because this is not a hobby it's an art form However, there are a few things that you definatly can't do... Chemically speaking.Propane/propylene oxidizes steel at 70% gasoline at 100%A propane/prop/o/a torch does not have the capability to jump through air gaps.  All of its core heat/energy is in the primary pre-heat flame.  Additional BTU's are lost in the secondary flame because of the combustion rate of those gases.A gasoline flame typically burns about 10x faster then the other fuels thus creating more BTU energy. Enough BTU energy is released in the secondary flame that I could mess around with a four inch tip and get ignition from 3 1/2 inches away. That's amazing to me. It all comes down to how fast a gas burns/combust's.  Acetylene is the hottest flame of the bunch and in my opinion the worst cut.Other oxy/fuel systems also can not compare on thicker materials.  2/12 in and below you will only see a minimum; difference in cutting time.  On a 10inch piece you would get blown out the water 4 to 5 times faster.  I know I have done it.  Check out this article and let me know your thoughts. Its on some DOE sight from a few yrs back.http://www.em.doe.gov/EM20Pages/pdfs...s/itsr1847.pdf

Reply:Originally Posted by soutthpawJP8 would be jet fuel.  Diesel would be good due to its high BTU capacity.   I see Petrogen has a GSA number so they are trying to sell to the US government / military.
Reply:You still cannot weld with gasoline as the fuel so why bother.  Use propane which is much safer.
Reply:The military need a JP-8 rig for logistics reasons. Compressed fuel and getting shot at mix poorly. Oxygen can be generated locally. Humm, their PO Box address is in Colorado Springs. This is something I should go demo... Heh
Reply:Try propane, it may actually be cheaper than gasoline.  Everything for propane is available at your LWS.
Reply:Originally Posted by gott2besafeYup that is it exactly JP-8 and JP-5.! Yeah they must have some military business with a contract.  If they really did design something that runs off all those other fuels and it works, er all could be in for a treat
Reply:yes you should try to demo the torch n share ur thoughts.  If your local I am pretty sure they could accomodate you, Yeah def can't weld with it things to Damn hot. However, since your cut is free of slag everything is ready to weld.  NO grinding.I checked their site and some lit, I have from them and they have many approvals.  UL being the main one, OSHA standards are meet, and they also sent me an MSHA approval.  I guess its the only torch approved for use in underground mines.Compressed gases def r not safer. In the wrong hands or careless mistake a backflash is always poss.  runnin liquid as fuel eliminates this? Gasoline in liquid form does not burn we know that only vapors.  In this torch it is liquid until almost the very end of the tip where a mixing chamber produces a vaporSlap your scrap
