Stimw, Thanks for the water warning. I'll be getting disposable dryers and when I plumb in my new upright compressor I intend to have some long vertical "U" bends with drains at the bottoms. My shop has A/C and I thought about wrapping an A/C duct with tubing to form a heat exchanger to condense water upstream of one of the drains that itself will be upstream of a water absorber. I'm too cheap to buy a freon/compressor type dryer.
My plasma maxes out at 27 amps but the next size up was $600 more, runs on 240VAC only and I don't expect to cut much thick stuff. My 27 amp unit has a switch in the back accessible through a slot to select operating voltage, 120 or 240. That is a handy feature as the unit is portable and I may go where getting 240 is a hassle. It sure slices 3/16 material very well and will chop off 1/2 inch (reallly ugly) and I cut some 3/4 round rod by rotating it (also ugly) I did have to make up an adaptor cord to be able to plug into 240 instead of following the instructions and cutting the molded plug off and replacing with 240 vac plug.
When starting a cut by piercing rather than starting at an edge there is some flying debris in the way of molten metal and slag that will burn the snot out of you if it hits and sticks to your skin (like your face.) So I intend to use a hood but with a large viewing area and use shade 4 or 5 depending on how high I turn it up. Murphy tries to make an example of me so I have to be more careful.
