Everlast 82i with 75 psi nitrogen instead of air.
Now thats how to do it.:grin:

Very nice @Bigdaddy2166 looks like your getting the hang of CNC cutting. :rofl: :rofl: :rofl: :+1:

Im not for sure, but I think that may be AI generated :grimacing:

No, I have not yet fully embraced AIā€”just a bystander for now. I am not sure itā€™s a good thing.

AI isnā€™t capable of doing the kind of work that @Bigdaddy2166 does! He is a master.

Thanks, Tom. Howā€™s my grammar lately? Iā€™ve been making a conscious effort. I am a legend in my mind. :rofl:

Itā€™s met AQL.

Thatā€™s all it takes and is much more reliable than an unconscious effort

Tom, maybe AI is just that good! I mean, if youā€™re gonna copy somebody who better than big daddy
I will say trying to get a copy of somebody as good looking as that would be hard to do, but you never know

Nah, sorry. AI is not smart enough to include the cigar in the imageā€¦ :thinking:

Now you just need to wire in a switching valve so you donā€™t waste the gas during post flow.

Great idea. I have two 3000 Nitrogen bottles and an F5 bottle plumbed into a manifold. It uses whichever bottle Iā€™m using. The nitrogen bottles last a month or so, depending on the amount of aluminum I am cutting. I donā€™t use it for anything under 1/4 inch. If I want to cut stainless steel, I open the F5 bottle. I have a separate supply pipe and use a quick connect to switch between air and the specialty gases on the wall behind the plasma table. It makes a significant difference on thick aluminum. The main benefit is that it shields the edge of the aluminum from oxidation from the air stream. I imagine argon would work as well, but it is much more expensive, although I have never tried it.

A single manifold with a row of valves, and 2 electric solenoids (NO and NC). One to regular shop air, the other to the manifold output. Wire the solenoids to the plasma fire relay, an an override switch to default to shop air only.

Is it time to make home-shop based air distillation towers for generating our own isolated gasses yet?

Liquefraction distillation column behind your shop. I built them for 30 years before I got this gig.

Going to need a giant air compressorā€¦

Define ā€œgiantā€ :face_with_monocle:

Might have to do those privatized micro reactors to power things though. Doubt split phase would cut it :rofl:

So do you get as clean of cuts if its under 1/4" and just air? Wonder why thickness would matter?

I find zero difference below 1/4 inch. I guess the IPM doesnā€™t let it oxidize. Iā€™m not sure of the scientific explanation.
