Well I guess this is close enough to our own section. So what does everyone weld with their OA setups?

My Craftsman (Harris) carried me for years (no 220v available in the house). But since I bought the TIG, I could almost throw away the O/A............. almost.
The first time I operated a torch was when I was in the 8th grade metal shop class; one of the assigned projects was a small hammer made of 1/2" square CRS, cut at an angle so it tapered to a wedge in back and drilled and filed to get a nearly square handle hole. I guess I put more care into mine than the average student and had even polished it nicely before mounting the handle, when the teacher asked if I'd like to harden mine. I, of course did although I had no idea how to; he showed me how to case harden it's ends with the oxy-acetylene flame, which I did for quite a while, afterward quenching it in water. I got it more than file-hard, but it surely took a long time to sand and re-polish the surface again! Anyway, that opened my eyes to OA torches and what they could do; by my college days, I had my own Harrris rig in the dorm room closet for a while.
I still have and use that hammer, mostly for working on firearms and other smaller stuff in my room. The polish isn't quite like new but the head still isn't mushroomed after the extensive use it's gotten.

Pictures! I mentioned the rain in another post. Here is what I tacked with the torch. It's already painted though, and sort of a temporary/semi-permanent fix...cart handle. Right on the edges, I want to try some more with the torch, it makes for a nice change in pace compared to mig welding on the time-clock!

...Don't often weld anything with Oxy-Fuel, but O-F is indispensable.
For example you could use it to:
Heat stubbornly stuck parts that need separating:
View attachment 28598
Or braze a handle onto a valve's brass stem:
View attachment 28599
Maybe heat up a pan of grits - or whatever that was!
View attachment 28602
Even heavy sections can be cleanly cut with a hand held torch:

And precise shapes can be cut with machine guided torches:

Oxy-Fuel is a versatile process that is very relevant to welding and fab work;
Yet O-F is uniquely different enough from any electric process, that it deserves it's own forum.
Good Luck
i found a brand new setup on ebay a smith or victor for 85.00 and that includes everything and i talked to the guy at welder supply store is it easier to lease the tanks or just buy em outright any thoughts? i guess it would depend on how often you would use oxy fuel

Well I own all of mine, (2) 150 acetylene (2) 250 Hydrogen (2) 250 Oxygen (2) BBQ propane. Add on to that all the Argon, CO2, and C25 cylinders and im supprized the ATF isnt on my case! Leasing isnt a bad deal for the bigger tanks. For people just getting into welding I usually recomend a set of the "burgular" bottles ( MC acet and 20cf Oxygen ) and a nice little carry-all. Then lease a big set if they have a big project. That way they always have something for a quick job, and arent paying lease on a tanks they arent using. On the same token match the tanks to the torch and work. If its a little aircraft style torch, then small tanks are ok. The big agricultural torches should be fitted to larger tanks, of course always following the withdrawl rules of acetylene cylinders.

Thought you guys might get a kick out of some of my "stable" of torches. With the exception of the large oxweld , all are in new or restored condition. The oldest here is the Marquette "P" from about 1921 and the newest is the Harris 19-6 from this year.

Naw,
The individuals and companies that designed and made these tools would make it immortal Unfortunately many do not exist anymore, and the art is dying. Smith and Harris are the only companies here in the US that still have burner engineers on staff. Smith actually did a re-design on some of their products in the last couple years, and my hats are off to them. The new valves on the AW1A handle are a vast improvement, and the new regulators are wonderful, with a touch of elegnace in the cast handles. I was sent 2 prototype sets of regulators to test a couple years ago....and your going to have to pry them from my cold dead hands. Unfortunately quality of design really matters when it comes to torch performance, and its lacking in the mainstream tools. I sometimes wonder if this is part of the casue of frustration for people trying to weld, especially materials like aluminum and nickel based alloys. Oh here is a pic of the latest soon-to-be edition to the torch family. A 1913-1915 Oxweld W1, this is about half way through the restoration and overhaul. Valves are all new, soldered joints repaired and tubes straightened and dents removed. Once I machine a new mixer and tips we are all set! Oh and the threads are all metric non-standard.

The older I get, the more aggitated I become about not having longer to learn more about welding (doing, not reading). I'm a hands on kinda guy (only Perfect is close enough) and when my electro-mechanical trade went electronic, I was trapped; too many years invested to restart.The individuals and companies that designed and made these tools would make it immortal

Funny, when I was younger, I didn't give a hoot about history; now it's fascinating. Thanks for the lesson and pics. The metric threads surprised me, not made in America?

Yep it was made right here in the USA. But remember durring that time period we had not really adopted the UN thread system. The metric system was already established in europe. Many times you will find threaded parts from the WW1 era that are neither english, metric, whitworth, BSA, BF, or anything. Thats when the fun starts!

Damn Makoman 1860. Thats pretty serious machinery you got there buddy!! Im looking to get a DHC 2000 this weekend. Out of that entire lineup which torch do you like to use on butt welding 18-22 gauge sheetmetal?
