I've also found that nitrogen (dry air) makes for a better cut on aluminum

[burninbriar]

I seem to remember a thread a while back ago about aluminum aircraft panels. If I remember right, they are not to be cut with plasma due to the effect of the HAZ.

A good dessicant air dryer just prior to the Plasma improves the cuts and the tip life as well. The media can be recharged many times by heating to 250 deg untill it changes back to the "dry" color.

I cut some small patterns out of door skin (1\16) it was damp from being outside,but it worked well enough for what I neded at the time.
