Fibre laser

[TheSniper]

All, Sorry if this is inappropriate I looked for other areas to post my question coulnt find one.
My question is.
Can one buy a controller for a Fibre laser?
I have an opportunity to buy a 50W fibre laser. that I have no idea whats wrong with it.
IM doing some scouting.

Worst possibility I need to replace the controller. if so what if its no longer available... etc...
I know with a tyopucal gantry style system.a controller can be bought. what of a Fibre style laser?
Thanks in advance.
