I only had one "incident" many many years ago. At the time I did not have flashback valves, and back then they did not come with torch kits. I don't even remember what, exactly happened. This MAY have had to do with a newly acquired rosebud tip. If you get too much pressure on one gas it can force pressure down the opposite hose, and if the tank is empty, force it clear down into the tank. This can also happen if the tip is restricted by dirt, etc.
Anyhow I vaguely remember a bunch of popping and frying and high pitched whistling, and it wasn't long after that I spent the money on check valves. Nowadays, you can google it up and find YouTube videos

Purox made a good torch too, if they still make replacement tips etc.
Brush soapy water on your gas fittings after assembly to make sure they are not leaking, not wasting gas, and eliminate an unwanted flash bang.
The Victor and Miller kit at the welding shop has the flashback included. I’ve used a torch but, it’s been a long time. I’ll be sure to study up before using. The tanks alone cost $500-600 for the initial purchase. Both suppliers don’t bother with the small portable tanks. The total investment is roughly $1100. I’ve looked around for a used ones but, you don’t know what you’ll get. I’m going to have to think about it since that’s a lot to spend. Thanks for all the suggestions. Craig

if your just going to heat and cut and not weld why not use propane and then you only need to buy one contract for the oxygen .
I'm not sure what you're talking about. Is there cheaper but safe alternative? I'll research.
Might be worth a little drive. $200 Bucks with tanks.

instead of acetylene use propane i use a 20lb tank same regulators just change your tips to propane . you will need to plum your regulator to the propane tank . just common fittings .

That sounds like pure bullshit, what town is this? When I worked in HVAC, we all used the little "suitcase" tanks because you had to drag them all over the place, into basements, up ladders onto roofs..........
So far as LP for cutting just do some googleing.

If you want to do cutting or heating, the cylinder's have to be big enough to provide the volume for the your chosen tip.
A rosebud requires a lot of fuel. When I was looking into it, the local ertailer had me call Concoa and talk with a rep.
Here's something else to consider easpecially with older equipment.
See the gage set on the acetylene facing upward.
I don't know the full history, but there was a time when, at least in parts of the country, portable acetylene tanks had collars on them.
The gauge sets were designed to clear the collars. Where I am now, its hard to find those tanks. That becomes an issue because acet is not usually filled at your supplier. They send that to a facility and trade you a full tank IF they have one. Otherwise its a week or two week wait to get yours back.

These are sometimes designated POL (Prest O Lite) type of tank. Open the valve with a key.
Some now don't require a key but same situation regarding the gage.
They also dont seem to respect the standard color designations anymore - at least down here. Just a pet peeve.

Yeh, we used to have a lot of the collared tanks around here, too. I have a smaller "B" tank for an air/ acet torch I use for heating bolts on outboard, and it needs a "key" A "key" was part of my life in my HVAC years. It was on a cable permanently tied to the torch set. I've hauled that thing up uncountable ladders over the years.
I also have a set of the 10 cu ft bottles in a plastic carrier like is shown above in some of the posts. I rarely use it because the bottles are so small they run out really quick. Particularly if you are cutting.
If you are buying off Craigslist or on line ask the seller to measure the bottles before you go. My first MiG bottle I bought I drove an hour to get. When I got there it was only a 10 cu ft bottle. Looked larger in the picture. But I drove so far I bought it anyway.
The second one I bought was a 300 cu ft. Looked smaller in the picture. I also drove a long way to get it, so I bought it. Barely fit in my car. I was so big that it would crush my harbor freight welding cart. I had to bolt it to the wall & run an air hose. So I have screwed up both ways.

Hopefully you just misspoken.

I would think you could sell them and not lose anything, they are high priced around here. You might also ask your supplier about trades. Ox-Arc here has been pretty fair to me--I traded a couple different tanks for something I wanted more, with some "boot"
Something wrong with the argon/ Co2 hose to my MiG from a wall mounted bottle? Seen it done in shops before.
Yeah, I should probably sell them. I have kept them around for hvac work in case I needed them, but I haven’t done any in awhile since the refrigerants changed. I don’t know anything about the new home stuff. The last couple times I paid to have units installed.

I had acetylene on the brain, and glossed over to, we`re talking welding gasses now...
Put the fire department on speed dial.
Seems like we had some number of minor garage fires in my youth. We had this big, maybe 40 cu ft CO2 fire extinguisher. It was great. You could use it & put the pin back in & use it over & over. No mess to clean up.
