Does anyone have any eqperience with this? I found a product that makes 450-600 SCFH of 93% pure oxygen. It uses about 150 CFM of compressed air to make it, but that's not a problem.
I'm looking at using it as a substitution for our bulk liquid deliveries now. We run a maximum of three torches on 1.5" steel and much more frequently one torch on up to 8" steel.
I'm thinking that the remainder of the gases in the oxygen will slightly affect the cut quality, possibly making us step up a size on tips a little or slightly slow the cut speed. I'm showing a payback for the company at about 18 months for this at our past consumption, even after adding the electirc consumption for the compressed air.
I can't find amny people running these and really want to know why.
I don't have any experience with it but it seems like it would make sense if you are cutting a lot (sounds like you are).
If you are worried about the purity, you can order a few bottles from your gas supplier as a custom mix. I'd say 93% oxygen and 7% nitrogen would be pretty close. That would allow you to evaluate the affect of the reduced purity before biting the bullet. I wouldn't think it would make any difference but thats not based on any kind of fact.
I'm sure the company could provide references, maybe even see one in action, from one of their past customers.
