I can't leave them permanently coupled because the plasma cutter needs to be protected against sawdust and other stuff that could get inside it from the shop's interior air. So, the plasma cutter gets "put away" when not is actual use. Also, I figured out that I COULD get by with a LITTLE less...

I need to correct a statement i made: Earlier, I said there is no point in providing more than about 80 psi at the output of the Nitrogen regulator since my plasma cuter is designed to handle only up to 65 or 70 or 75 psi internally (can't remember what exactly off the top of my head). BUT, if...

Let's be just ab it more specific and accurate. In your exmaple, the "244 cf" means that the gas contained in that full cylinder would occupy 244 cubic feet if it was uncompressed and at "standard" temperature, sea level, etc". When compressed in the tank, it is obviously a much smaller volume...

Yes, I will be doing some quantitative testing. Here are 2 photos of the Nitrogen setup at this time: This is the dual gage & regulator set before I replaced the output nipple with a female NPT 1/4" fitting that accepts a standard air hose. I'll restrict the output psi to 80 psi or so since my...

My welding supplier just called me. They love what I am trying to do here, and they are going to adjust my Nitrogen gas refill charge down to make it more affordable so I can use as much as I want. :) Jim G

Trevj: I hope you did not regard my comments as disrespectful in any way. They were certaily not intended that way. You and a number of others on this forum have been SUPER friendly and helpful to me as I explore and learn about this new metal affliction that has possessed me. You have in fact...

Excellent question, and one that I have been researching with limited success until yesterday. Most of the websites you go to, including even the ones by organizations like Hypertherm, Miller, etc, are too vague in answering this question, implying that the right "combination" of amperage and...

Obstacles are made to be overcome. People asked me why learn how to TIG weld at age 72. Answer: Why NOT? Plasma cutting: same. Jim G

Here's a photo showing the "floor space"occupied by the Nitrogen tank: I still just have to buy 2 hooks and 2 lengths of safety chain to secure it to the wall. It apaprently holds 299 cubic feet, and is only 9" in diameter. Its location right by the overhead garage door made it very easy for...
