CT 416D Multi unit

I had bought this unit off ebay a several years ago. The unit on ebay was blue but this one arrived yellow!! I was told that they were the same unit, just yellow now?!?!? The instruction packet lacked alot!! So far all I have been able to do is the AC/DC welder part of the unit. Can you help me with setting up the plasma capabilities of the CT 416D unit? The brochure is not very specific. I am trying to hook up to my shop compressor, but I only see a barbed fitting in the back......and a barb won;t hold pressures higher than 60 with out probably blowing off!! Can anyone help answer my questions and concerns please. I would appreciate it. Thanks in Advance.

No, the pressure will hold much higher than 60 psi. Check our website for the manual. Use dry air and a filter. You should have had a filter or something along with a hose to connect them.
