Dealer claims "low press N2 is new trend" ??

Dealer claims "low press N2 is new trend" ??

Dealer claims "low press N2 is new trend" ??

(OP)
In looking at new and used machines we recently had a dealer with a laser background make the following claim.  "High press nitrogen is old school, with todays high purity N2 and advanced nozzels its not needed in a machine."  Is there some new process/method that this applies to? I think it is BS.  To boot they have a low press piped machine (130psi) they are pushing.  Small wonder.   

Our apps would include .5" & .6" 304 SS

Any advice or knowledge on this "new process" would be appreciated. Thank you zmm

lol.

Or, maybe I'm old school. Haven't heard of that one. Funny thing is that he is talking about "new technology" but used machines.

RE: Dealer claims "low press N2 is new trend" ??

Sure, if you don't mind grinding, low pressure is great...

RE: Dealer claims "low press N2 is new trend" ??

Maybe they use like a 6 mm nozzle? Who knows, never heard of low press n2 cutting. Have him cut some thick parts with a reasonable shape and see what happens, my guess is nothing good. I've seen as low as 7 bar on some thin stainless with good results but I can't see it on the thickness you mention.

Maybe he should sell used cars.  I called his servce guy today, he said "what" ?  Owner called a time later with a   ah  ah  ah what meant was....etc.  Fast talk no content.  Thnaks for the replies fella's  !!!

RE: Dealer claims "low press N2 is new trend" ??

Look into Laval nozzles it is a venturi type nozzle.  The shape causes a increase in velocity which causes an pressure increase at the work piece.  I have tried them however the process window cutting with these types of nozzles is very small.  You can get approx a 30% increase in force however the standoff distance is a factor.

RE: Dealer claims "low press N2 is new trend" ??

May I ask what dealer/manufacturer made this claim? I am very curious about this.

RE: Dealer claims "low press N2 is new trend" ??

if you're still looking for used machines tell me which kind and maybe I'll be able to help you if it fits what my people gets. Anyway about your question I would be very careful about this kind of arguments, I've never heard about low press cutting, and if he's pushing his machine according to his argument I think it's clear, he just want to sell!
