Tube and power supply upgrade

Hi all,
my 80W laser tube failing (the cooling water go everywere in the tube, also in the inner tube), so I bought this 2 product:
https://www.vevor.com/collections/la...utting-machine
https://www.vevor.com/products/150w-...106f6cd7&_ss=r

I choose a bigger power supply to future upgrading. But now I notice that the laser tube need 26KV, instead power supply voltage output is 34KV.
I understood that the output power is adjust with current set from controller, but how can I set the voltage? Or the voltage is proportional to current?

Thank you for your support.

I answer to myself.
Vevor (laser tube and power supply vendor) told me that the power supply auto-set the voltage to correct value.
Anyway, today the tube arrived and I put in my machine with original power supply (80W 40kV). All work correctly (I think: the beam out from tube). I must align the mirrors and make an extension for tube coverage.
