Brand new Ebay Blue/White 100W RECI CO2 Laser
Problem: Extremely low power, even on 80% power. Barely cuts paper.
What I’ve tested so far:
I realigned all mirrors.
Raised the focusing lens housing.
Verified that focusing lens is rounded side up.
Verified incoming power (110V)
I have a MA meter arriving tomorrow so that I can verify the milliamps at the tube.
What else am I missing? What could cause low power like this?
I’m experienced in CO2 lasers. We have a 130W red/black since 2016.
Thank you in advance for help!
