I just bought a used powermax 30 air and it has a different design on the gun compared to my powermax 45. It has a plastic deflector with number 420399 that seems to be burned. In the consumable kit there are only Cooper ones with holes in it and they look Quite different but has the same part number. I also see Jim from hypertherm not recommending the plastic deflector on thicker cuts but what about the copper ones?
Reply:I read the Jim didnt like the deflector on thicker cuts too. I thought he said the same for any cuts. I was very disappointed with how my 30 air cut. So I took it off and was very happy/ impressed with how much better it cut. Any one else see similar results? I had the metal deflector.Last edited by Landroverbill; 07-16-2021 at 10:08 PM.
Reply:I will test mine with the metal deflector today and see if I get the same result. With the plastic deflector if I didn't keep a distance to the work piece I got molten metal on the nozzle with my first test cut so I assumed something was wrong. I don't have much experience with plasma cutters tho so it could be user error.
Reply:Here is the one that was installed on the gun when I got it. Now all the parts with this number is copper and has holes on the sides. Also the ones in the kit I got. I guess it's just to get some testing done and see if I can spot the difference in performance
