oxygen

I worked for a long time in a co-op with oxygen by the tank. I'm debating wether to try that in my new shop or get a concentrator. Any thoughts?

Unless you're going to use a ginormous torch with high oxy needs, a concentrator will pay you back in no time. Mine's almost 20 years old and still chugging along.

Really depends on the torch and what you make.

A 10lpm concentrator will work solid boro up to around 1" and hollow boro up to around 1.5". I have one and rarely need to turn on the additional ones, only for the biggest jobs.
There are differences in outlet pressures with 5, 8, and 20 psi being the most common. Not always clearly stated but the higher the better.
If you run it around 8-9lpm you get nearly max purity with max flow. And nothing beats eliminating empty oxy tanks, delayed deliveries, and tank ownership issues.

Some people go to the next level and incorporate a system to pressurize and store the oxy in a tank, then draw from the tank at higher pressures. I just stuck with the oxycon by itself set to 9lpm and turn down the propane as needed to make smaller flames.

Good luck whatever you decide!

And another option is to use a Home fill oxygen setup, just to confuse things a bit more. Or if you get a concentrator and wish you had tanked, you could get the homefill and use it with you concentrator to fill your tank.

what about filling a tank with a concentrator? Does anyone do that? I work with a a lot of boro and it would be a terrific bother to keep getting tanks filled at a depot.

That is what the homefill does. You have to buy the actual apparatus that compresses the output from the concentrator and it's hooked to the tank to fill it up
