The best one is one that will supply the amount of air that the Powermax 30
requires to run full throttle for as long as you need to cut. The CFM
rating will be given in the manual. That way, you won't have to stop
cutting to wait for your compressor to catch up.
That said, then you go to brand names, and different types of compressors,
and other things.
If you are going to use the plasma cutter intermittently, then you can get
by with just about anything that will give you enough air for say five
If you are going to hook it up to a CNC unit, such as a PlasmaCam, then you
want something that will provide enough air for an hour. Hence a larger
compressor, and a better one, as a lower grade will wear out in about three
months of that kind of use.
And now to other things. One of the most crucial things about a plasma
cutter is a dry air supply. You must be sure to have the adequate number of
filters and driers. It will probably take more than one. The air must be
After that, you will have to fine tune and tweak according to your specific
If you're looking for a number, I'd suggest you buy a compressor rated at
110% of anticipated need. If you're looking for a brand name, it's up to
your pocketbook, although you can get a good used quality unit that will do
the job and last for a lot less than a new one of the same flavor.
Keep us posted on how it goes. Plasma is a whole new world. CNC is like
alien technology. You're gonna love it.
Ah - PlasmaCam is a walk in the park. Just start walking in the daytime.
Take notes and keep a head.
I have one.
