The portability is an interesting point. To me, it does not matter. I have the nitrogen cylinder chained to a wall and a 25 foot 3/8" air hose to place the plasma cutter anywhere in my workshop. But, yes, the Nitrogen is easier to transport than a big compressor to get into and out of the back...

Wow, that's a costly and very noisy solution! My ONLY tool beyond the plasma cutter that requires air is a finishing nail stapler, and my pancake compressor is more than adequate for that. I simply cannot justify the cost and noise of a big compressor (or multiple smaller ones) to feed just ONE...

I have been super busy, but got a chance in the past couple of days to make some progress on both my TIG welding and my plasma cutting testing. I had previously put together a 25 foot 3/8 inch air hose with quick disconnects to connect my 300 cu ft Nitrogen cylinder to my BestArc lunchbox size...

With Amazon's help, I contacted BestArc, the seller for the model I have, and asked what air pressure is allowable to feed into the machine (as opposed to what psi is set INTERNAL to the machine. Here is the conversation I had with them: BESTARC 18-Feb-2023 6:37 AM User manual says to set psi...

What specifically do I buy that would fit via 1/4 NPT quick disconnects between my airline and the plasma cutter? The combination regulator/psi gage/flow meters I have seen have Argon gas fillings versus NPT threads that can accept male or female QD fittings. (I am very new to this gas flow...

I would like to keep the system as simple and robust as practical, so adding a flow meter and an additional pressure gauge is not attractive to me, especially since the additional hardware would need to somehow hang precariously off the water filter male 1/4 NOT fitting on the plasma cutter...

Aurbrushing sounds surprising at first given that airbrush artists usualy take minutes or hours versus seconds to do their work, and Nitrogen is not tnat cheap, but then you realize that an airbrush uses VERY little air or gas. When artists use airbrushes to paint for example, where the air or...

There are multiple reaosns that some operators use Nitrogen or Argon for plasma cutting or airbrushing. Quality is one. Noise is another. Eliminating oxidation is another. Better temperature stability is yet another (this reason, along with zero moisture content no matter what, is why Nitrogen...

This postflow air or gas consumption seems to be a big deal with the plasma cutter manufacturers. The user manual for one Hypertherm model says the following: " How the system handles postflow for marking Postflow is gas that flows from the torch in order to cool the consumables after the...

Yes, I was offered a 2300 or 2400 psi N2 cylinder and went with that. If i am reading that first full colour graph correctly, a 3/8" line can flow 20 CFM, but a 1/4" line only 10 CFM, so my 3/8" line with 1/4" fittings is likely a bit above 10 CFM capability. That's good. I did post a question...

Yes, I checked, and the instructions for my plasma cutter say to set its built-in regulator for no more than 75 psi. The instructions are unclear as to whether that means I should ALSO not let more than 75 psi come to the machine, or whether it is ok to feed a higher psi to the machine, but keep...

As I have mentioned elsewhere on the forum, i have a tiny lunchbox size plasma cutter, the Bestarc BTC500DP, which uses an AG60P pilot arc torch. Looking as best I can online, it appears this torch is rated for use in the 40 to 60 amp range. I assume the consumables are sized for that range...

Deep within it (page 19 ! ) the Everlast user manual contains this scary warning: " Regulator/Filter/Water Trap. This regulates the cutting pressure of the unit. To adjust: Pull up firmly but gently on the regulator knob until the detent clicks (about 1/8” or 3mm). Rotate clockwise to increase...

That Everlast manual also says about postflow: " As a rule of thumb, use 1 to 2 seconds of post flow for every 10 amps. Longer post flow times may be used in cases where long, uninterrupted cuts are being performed. " So, postflow duration versus amps might look like this: AMPS / Postlow...

In examining an online pdf of an Everlast plasma cutter user manual, I found this interesting statement that applies to their 60 to 80 amp units: " Use this as a general rule of thumb for good hand cutting speed and quality: For the first 1/8” of thickness, use 20 amps. After the first 1/8” add...
