How To Replace The Nova Series DC Tubes

How To Replace The Nova Series DC Tubes

Firstly, turn off the whole machine power.


VIDEO HOW TO:




INSTRUCTIONS (may vary but the principle is the same):


Tools\Supplies Needed:
3mm Allen Key (For Tube Straps, Extension Access Panel and HV plug retainer set screw)
Flat Head Screw Driver for Negative Lead on 80W and higher machines
5.5mm Wrench or Socket for Analog Ammeter Machines (60w and lower)
Snips - For Zipties on water hoses

Zipties (2) for Hoses



Remove Old Part:


1. Unplug the wire between laser tube and laser power supply and take out from the hole, like below (Nova 24 shown).



 For 80W, 100W, and 130W machines, the Negative Pole will be on a white Connector in the Tube Box at the End of the Laser Tube



2. Prepare the tube for removal


① Cut the zip ties



 For Nova 24-60W and 100W Nova 35, you will need to access the tube end behind the extension panel:




② Remove the Tube Strap screws with 3mm allen wrench



 


3.Drain the water away from the tube.



 Then Remove the Water Tube Feed Lines:

Gently twist and pull them off. If they will not come off, cut the water feed lines flush with the tube bung.


Install New Part:


In order to ensure laser path correct, location of new tube should be the same with the old one.




Tech Tip for Nova 24: When installing or removing the HV white connector on the right hand side, it may be easier to pull the flexible water hose through the bushing to create more space for the larger white HV connector to fit through


Then fix the tube and wire.
