I had some 1/4 in AL to test the plasma cutter. The AL is painted on one side. I used the tip spacer in the torch. The settings are as followes.
50 amp
AC
I changed the air pressure from 65, 40, 30 psi
At 30 psi the plasma tip wes destroyed.

Keith,

Try increasing the PSI as well. I believe he had it all the way up to 80PSI when we did our demo.

Thanks,

Simon

The cutting was easy from 65 to 40 psi, at 30 psi it turned to S#$%!!!
I was trying to show the effect of air pressure on cutting AL. The cut is much better than the pictures show.
