Bert,
Campbell Hausfeld makes a nice combo Air Cleaner/Dryer (Model PA208501) which is a nice little unit. Includes both a filter element (replaceable) and a desiccant element (replaceable granules). I had my local hardware store (CH Dealer) order one for me. Runs about $100 retail.
I use this unit at the plasma cutter and it seems to work fine. My air is filtered by a Binks (Paint Grade Filter) prior to going into the 50' 1/2" line feeding the plasma.
If you're using the Motorgard filter (I think that's what Hypertherm recommends), I can't imagine that moist air is what is causing the problem. For 3/16" material, I would try the fine cut tip.
Although I have never used it, several posters here have used Nitrogen rather than compressed air. It's about the cheapest gas you can buy and supposedly, works great with a plasma cutter. I can definitely see the advantage in portable work.
Hope this helps.
