Air pressure settings for new x45 torch

I just got a new x45 torch lead for my razorweld 45. It doesn’t cut near as fine as my old torch lead. Do I need to adjust air pressure settings for this new lead. And if so what do I need to adjust it to?

That’s because you only have 1 (one) cutting tip/nozzle to do the job of 4.

I’m not sure I completely understand what you’d meaning. I only used one size one my old one also

Well you could get 20,30,40 and 50 amp tips for your old torch. The x45 only has 1 tip that covers all 4 sizes, like one size fits all.
