How to make the most money with a cutting torch?

Hello, im new on this forum and have been reading alot on here for advice. One of the threads I read someone was talking about how much they didnt make with steel and someone else said "I make tons of money with steel, you just have to know how to use a torch" . But then they kind of left it at that. Im wondering if anyone can really expand on what this person might have meant by making the most money on steel by using a torch? All I can imagine is that they were alluding to taking the most valuable parts to sell off of a scrap vehicles or machinery in minimal time with a torch instead of wrenching things off? Im not sure really. Thanks.

Miked, it was Pistonescrapprocessing

Okay, thanks alot. Turning motherloads of big steel into numberone, just didnt cross my mind. Locomotives and powerplants, I can see how there would be huge potential in steel coming across stuff like that. Gotta truly think large scale.

Welcome from Mesa az. It's not cost effective to use a cutting torch on a small scale. I build hot rods and other stuff from steel. The last time I filled my large oxygen tank it cost $40 bucks. If cutting a lot with the gas wrench the tank does not last very long. That expense makes less profit. For me if it cannot be unbolted or cut off with a grinder or sawzall I pass on it.

Thanks for the shoutout. I still check in from time to time. Still got guys cutting up scrap daily. What is the question I might be able to answer it?

What kind of setup does it take to use the liquid oxygen? Will it work in the cold, below zero temps. F?

The liquid tanks are a large thermos, when filling liquid oxygen at the plant O2 enters the tank with extra and I mean a lot of extra oxygen being bled off to atmosphere the bleed off cools the tank and contents to sub zero temperatures.

Now that the tank has been filled, the contents should be put to work imediately or as soon as possible, as you use the oxygen your drawing gas off as a vapor which in turn is used to keep the inner contents cooled down.

Liquid oxygen is not something you order then expect the tank to remain full for a year, if not used then as the contents warm up the tanks are designed to automatically bleed off. Think of it as a self contained refrigeration system, the more product you use the colder the contents.

Definitely not meant to be used indoors, those that use a lot of oxygen store these cylinders outside with plumbing to the work stations.

Piston has access to larger liquid tanks where the truck comes to replenish the product, same as the hospitals would have a large tank somewhere on the property. The larger liquid tanks actually have visible condensers.

If your ordering a liquid oxygen they're filled to order.

If your doing a lot of cutting you have another option, you can order in a cylinder cluster. also with a cluster there is no need to be contually drawing gas from the cylinders to keep the contents cooled down.

With oxygen the more you use the cheaper it gets.

On both set ups a regular cutting torch regulator works, I used propane for my fuel with a Harris torch made specially for natural and propane gas.

My Harris torch was thirty some odd years old before I had to send it in to have a leaky seat repaired.

These torches also come in various lengths, I preferred the shorter one over the much longer one preferred by the scrap yards who most exclusively use Harris.

i find it quite interesting that no one has brought up the gas powered saws. Its basically a 14" grinder. When I'm out in the field I use the saw to cut up whatever I can, when something is too awkward or I cannot reach it I break out my little torch set. I picked up my victor torch and victor gauge and two airgas tanks at an auction for 80 bucks, I hardly use it but its nice to have.

Also with the big saw I like to cut my electric motor cases. Its quick, and it cost a lot less then a 4 1/2" grinder.

Of all the things that i have cut up for scrap tons of logging cable in a rats nest is the worse yet, it's springy and has to be cut into 3 ft lengths otherwise the yards won't accept it. Since I always got it free never turned it down.
