What are you guys using for air? Plumbed into your shop air or using a dedicated compressor?
I just unpacked my cut50 and the literature says 6.4cfm and 100psi. That is a fair amount of air to provide.

Right now, I'm fabbing up a bracket to put my new filter on a portable compressor I'm using for air on the DR. I can see hooking permanently to a whole shop system if this was gonna be used that much. My use will be minimal and I'll keep it with the portable air supply so I can move them around more.

I have a Ingersoll Rand shop compressor 19.5 cfm @ 100psi and I mounted the M60 filter on the plasma cutter so I can hook it to any line in my shop or any where else.

Until I started looking, I had considered a smaller unit so I could put everything on a cart...the smallest unit that I found with 6.4 is quite large, at least for a cart, so was just wondering what you guys were using. Looks like I'll plumb into the shop air.

Unless you get lucky, I don't think you'll find a portable compressor that will maintain 6.4 cfm at 70 psi
A plasma cutter requires around 70 psi continuously, to cut correctly. You can get by with 60 psi.
The following compressors would handle your needs at 70 psi if you use the plas in short intervals.

Senco PC1131 Compressor, 2.5-Horsepower 4.3-Gallon

Emglo AM780-HC4V 2 HP Electric Air-Mate Compressor

I have a couple of portable units in the shop that make 6.4 at 90psi but they are kinda big. Since most of my equipment is a bit 'old' (not unlike me), I just wondered if something newer might be in the market place that was smaller.
Thanks.

I wish I could find time to use mine. I have a 6 gal compressor that builds 150 psi, don't know if it would handle it or not. Never thought about a cart and compressor combined. I 'll more than likely use my shop compressor, but that got me thinking.

Some more use on my Cut 50. I have an old water pressure tank build date 16-10-44 that I'm making into a chimmea for camp, It is rusty 1/4" steel and I cut 4 large opening in it with ease. I found the plasma eats consumables at a fairly fast rate on the rusty steel.

A suggestion,
I install new consumables for the jobs that need to be cut clean and square on the edges until they start to cut on a bevel then, I switch them out, I keep all the consumables in a Holley jet box in the category of wear on them, I then use them on thinner materials until they start to cut bad.
Rust is hard on tips so, I use the worst ones for just the type of job you're talking about until they won't fire or cut, I then throw them in the copper recycle bucket.
You will get more use for your money that way.
