I have cut 1/4" aluminum with my Crossfire PRO and the Primeweld CUT60. However compared to the same cut in 1/4" steel, the edge finish is nowhere near as good. I get a much bigger taper and I need to do a lot of cleanup. Unfortunately I already done that so I don’t have pictures, but I will test-cut some parts now to try to find better settings.
Besides the obvious from the cut chart, 45A, 60PSI, 54IPM (1380mm/m) what should I try? Pretty frustrating being used to the results in steel…
Oh thanks, yeah I’ll use 60PSI anyway - what about the torch nozzle, do you use regular consumables? I really hope to be able to tune this and get nicer edges
The chemistry of cutting steel vs aluminum is very different. Steel reacts to the plasma and actually fuels if, cutting much more cleanly than AL which only melts with the plasma’s heat. Consequently, for AL, you want lots of heat and fast moving to keep it reasonably smooth edge.
