Daily: Two Minutes Before You Start

Check the chiller water level and temperature - 18-25 degrees C is the healthy band for glass tubes. Glance at the lens for haze, confirm exhaust airflow, and clear debris from the bed and rails. These two minutes prevent the majority of mid-job failures and bad cuts.

Weekly: Fifteen Minutes That Save Hours

Inspect and clean all three mirrors and the focus lens with proper optics solution and lint-free wipes - never dry wipe a dusty lens. Check belt tension on X and Y axes, clean the nozzle and air assist line, and verify the bed sits level. Misalignment discovered weekly is a five-minute fix; discovered monthly it is an afternoon of re-teaching yourself alignment.

Monthly: Deep Care

Deep-clean optics, inspect tube output by running a power test - if max power has faded noticeably, the tube is aging. Clean exhaust fan blades and ducting; a clogged exhaust quietly steals cutting power and fills the room with smoke. Flush the chiller water every one to two months with distilled water only.

Chiller Discipline: The Tube's Life Insurance

Ninety percent of premature tube deaths trace back to cooling: algae-blocked lines, tap-water mineral scale, or a chiller set too warm. Use distilled water, keep the setpoint in the low twenties, and listen for the pump - silence or gurgling means stop cutting immediately.

FAQ

How often should I replace the CO2 tube?

Expect 3,000-8,000 hours depending on cooling and duty cycle. Replace when max power fades past the point your production speed needs, not when the tube dies completely.

What is the most preventable failure on a CO2 laser?

Dirty optics. A dusty lens absorbs heat, cracks, and then misaligns the beam downstream - one weekly wipe protects the whole optical chain.
