Hey guys! The "propane touch" thread reminded me...
I have a Turbo torch waiting down at the welding supply house. Ordered it a week ago but haven't picked it up yet.
Any advice on these things?
I've never used one.
You just hook up acetalyne.. right?
Thanks!

My only advise is not to try to turn down the heat by backing off the gas pressure. You will burn the tip up. For less heat use a smaller tip.

When you are through ' let it idle for a while so you don't ruin the turbo bearing:D .

Henrob Jim, he has moved into a newer house out in the country. talking about taking on a regular job. I guess selling a expensive torch sucks at times. A damn nice guy. No connection other than met him a few times. Watch the videos on that site there..

Since prest-o-lite was bought out and the patent expired years ago. most of the brands Uniweld,turbo torch, Goss, etc parts are inter changeable.
I have a number of them by different companies and every thing is swapable.
On the tanks incase some body doesn't know B stands for Bus and MC for motorcycle as that whats the size was used for back in the day.
When buying tips and replacement parts, make sure they are for the acetylene/air version not the propane/air version as the have two types.
Also unless you are going to be toting the tank on ladders etc get the large tank. as the MC costs as much as the B around here.
They are great for the plumbing, heating and light bending, forging, along with light brazing and silver solding in jewelry work.
The MC requires an adapter to hook up to the regulator. And the wrenches, Buy a couple as they seem to built to self hide every chance you get. Mostly on a ladder miles from a source for a new one. using an adjustable one causes the soft brass square valve handle to twist up at once.

About the only difference between this one and the real turbo torch is the color of the handle. As far as the propane air there are about 5 sizes of tips.

I've got one, but I never used it for aluminum. I just use it for general heating around the shop. I've also got one of the propane regulators, but I actually use that on my oxy propane torch...acet is just too damn expensive, plus I find propane tanks on the side of the road while scrapping. Figure that one out. Picked one up yesterday that was half full.

Thanks guys! Glen.. that's the ones.

The little wrench.. lost it quite awhile ago :D

The reason, you find them (propane tanks) is that some can;'t be filled with out the modifications of the valve, cheaper to buy a new tank. Or they have the type of new valve that shuts off the gas flow all the time. There are a couple of different style and only one works good for high flow rates.
But the biggest reason is they are considered Hazardous waste and have fees for disposal to match. so you can put them out with the trash like before. As around here, the scrapers won't take them because they don't want to deal with taking them apart to scrap em which requires they have a hole cut in them after a complete wash out.
Here is another money burner unless you happen to be on a ladder, or under/inside some equipment were you can't get a real torch.

If I remember correctly the MC tanks equals about 15 or so of those little tanks.

If you live at any sort of altitude don't bother with a propane version. The mixture isn't adjustable and propane has a very narrow range of ignitable mixture. Anything over about 3000 ft and it starts to be a real problem. At 5000 ft you probably won't have much luck getting it lit as the oxygen partial pressure is about 1/3 lower than at sea level which makes th mixture too rich. Acetylene is entirely different.

The burnable mixture range for propane is 2.1 to 10.1 percent in air while acetylene is 2.2 to 85% in air.

Another reason to find propane bottles at the curb is that movers generally will not move a tank. The owner usually finds that out at loading time and the curb is the only alternative. I always thought that B was the abreviation for omniBus and MC for Motor Car and that motorcycles used generator type acteylene lamps slightly larger than those for bicycles.

Yeah, I tend to find the tanks with grills. People buy a new grill and don't think to save the old tank. I don't get it. I mean, I completely understand the ones with the overfill valve, but I'm finding new ones lately...and these aren't people moving, they are just retarded.

The empty ones (non-refillable) get the brass valve removed, filled with water, crushed with the front loader, then to the trailer with shred steel. Never had them say a thing about it, but they don't say anything about fridges and freezers anymore either, steel is too high for them to care.

Another reason to find them is from Meth labs, so be careful what you are grabbing :)

Well the old guy, at the welding supply said that why the valve is angled because they strapped to the cross bar angle upright. Could be different place now different name. the other place that I got a tank refilled called them mini cylinders so I guess its what you what after all you own them:D
Omibus is a bus I believe on this side of the pond.
