Preface: This article covers the basics of swapping out the tube of your Nova series Laser. Depending on the model and vintage, there will be some slight differences. We recommend reading the literature below the video to get a better understanding.
Zip-ties (2 min) for Water Hose connections on New Tube
1. Disconnect the power wiring between laser tube and laser power supply. There will be a black wire and red wire to disconnect.
Black Wire on Ammeter | White Connector for Red Wire |
Use the 5.5 wrench or socket to remove the nut from the post. Then remove the ring terminal off the post. | Use the allen key to loosen the bolt holding the white connector in place. Remove the white connector out of the holder and unscrew the two halves. |
Negative Wire | Wire Connector for Red Wire |
① Cut the zip ties that are holding the water tubes and red wires in place. Also you will need to bend some retainer tabs out some to release the tubing and wire. Do not over bend.
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. The straps may be "stuck" to the tube somewhat. Lift them up and around off the tube surface
Lift the tube up gently on the right side to let the water drain back out to the chiller
Then Remove the Water Tube Feed Lines:
Install New Tube:
In order to ensure laser path correct, location of new tube should be the same with the old one. The total distance to the beam combiner is not critical but do allow for the dust cover to fit on the 100W and 130W tubes. Install in reverse and be sure to terminate the Black wire on the proper terminals.
