I was reading some old posts on oxy/propane cutting and came across this. Link the Idea is great, I just dont see how they can justify 1,100.00 for the tank and troch, when all the tank is, is a gloified propane tank. has anyone ever used one of these things?

I saw one of the posts on here about a different kind called O-petrol I believe it was. That same evening I saw a show on the Discovery channel about one of the militarys, crash/salvagee/disaster response teams, and they showed them cutting with one of these gasoline fed torches. I've never had the opportunity to use one of them but I have heard that they are great for cutting extremely thick pieces (10" plus if I remember what I read that night),and it doesn't mind wether it's clean or dirty and rusty. Plus it'll do several pieces layered, all things a standard torch won't cut without alot of trouble. I heard it burns almost as hot as a plasma which gives it it's greater cutting capabilities. I know the initial cost is high but if you have a need for it's capabilities it's a steal at any price. Not to mention one gallon of gasoline, even at todays prices, is way yonder cheaper than a comparable amount of aceteline.

I have used the Petrogen cutting torch, they work very well on thick rusty or dirty metal. They do NOT run on propane,they run on regular gasoline which makes them much cheaper and safer to run/transport than acet/ox systems. The tank holds liquid gasoline and has a small hand air pump to pressurize the tank to deliver gasoline to the cutting tip.

yeah, what I ment by Propane is that tank looks like a 8.00 propane tank with a hand pressure pump on the top and a couple of gauges, would be interesting to see what Actualy makes this worth 1,100.

Perhaps their liability insurance makes it worth the extra $$$!.

Not to critcize a product I know nothing about, but is seems to me if you ever accidently damaged or burned a hose, it would be quite annoying to have gasoline spraying about under pressure!

I suspect the fact that petrogen is the only source for a gasoline fueled cutting torch(other than a made in China knockoff with less control features),and the fact that heavy industry and military are the main ones buying them,allows the high price. I suspect they are little if any more dangerous than a dry gas fueled torch,as they have an excess flow valve at the tank that blocks the gasoline flow if it exceeds the normal very slow, aprox 1 qt per hour flow rate. The only difference when operating a gasoline fueled torch is that when you start it you must bury the tip in the flame to pre heat it to vaporize the gasoline. A relative of mine who is a rigger that specializes in dismantling and moving food processing plant equipment likes the gasoline fueled torch because the fire ordinances in many of the places he works have very strict rules about the transport and storage of acetelene(sp ?)gas.They are much more forgiving of using gasoline,plus the gasoline torch works so much better on mounting bolts etc that have thick layers of paint or crud on them.
