Just purchased a unimig viper cut 30 mark 11, looks great but the arc/cut flame only lasts for a couple of seconds and drops out, have put in a new electrode, new tip, (even though we have only used it for 5 mins). It’s plugged directly into the 3hp compressor running at 90psi with about 1m of air hose, have ground the steel to give it a good earth, running it on 2t on standard.

Air pressure needs to be maintained above 70 WHILE cutting.
A small compressor needs to be able to keep up.
Send us pictures of your setup so we can help you. Raw voltage? Or divided voltage? Laptop or desktop? Type of torch and where the consumables came from. Hopefully not Plasmadyne… etc
What error screens are popping up. Send us a screenshot of the warnings or error screen on FireControl.

Unimig Viper plasma cutters are mostly sold in Australia not here in the US.
Air should be set on the regulator to 75psi. Also cutting tip must be with in a .060" or 1.6mm to the metal being cut.

Welcome to the forum. You sure gave a lot of information in three sentences. I would call that a good first post!
What table are you using? Does it have an active z-axis (does the torch move up and down with a stepper motor)?
The reason I ask, is that you can test your your cut height with this file if you have an active z-axis. That is what @mechanic416 is asking you to ascertain…and is a good thing to rule in or out as far as problems.
