Air Compressor Size for Razorweld 45a plasma cutter

I’ve been looking and maybe just overlooked it but does anyone know the air compressor CFM at 90psi needed to operate?

The CFM rating is 6.7 for the razweld cut 45.

If you need 6.7 cfm you want at least 10, 12 would be better. Most compressors these days are not ment for continuous service, if it has to run consistantly they tend to burn up.

( Recommend) Big reservoir to… 60 gallon +

On long cuts I let my tank fill to max capacity first.

It’s switched on a few time during a bigger longer cuts, and the compression pulses sometimes showed up in the cut and you can notice it in the plasma arc as it’s cutting . It’s happen once or twice but not always
