About Glass Settings for the OMTech OMTech CO2

The OMTech OMTech CO2 cuts Glass cleanly at 40 mm/s with 12% power. Because the OMTech CO2 is available in multiple wattage variants (80W, 60W), settings are grouped by wattage above — select your laser's wattage to see the right numbers. Always test on a scrap piece first — every machine is slightly different, and variables like tube age, lens condition, and material batch can shift results.

For Glass, the key variables to dial in are speed and power. If the laser isn't cutting through cleanly, slow down or add a pass before pushing power higher — excessive power causes charring and wider kerfs. Air assist is highly recommended for wood and organic materials to clear smoke and protect the lens.

Once you find settings that work, save them in Laser Lab to build your personal settings library. The AI predictor uses your calibrated results to suggest starting points for new materials automatically — so the more you log, the smarter it gets.

Frequently Asked Questions

What speed and power for Glass on the OMTech OMTech CO2?↓

For cutting Glass on the OMTech OMTech CO2, start at 40 mm/s speed and 12% power. These are manufacturer-verified starting points — always test on scrap first.

Do I need air assist for Glass on the OMTech OMTech CO2?↓

Air assist is strongly recommended when cutting Glass. It clears smoke from the cut path, reduces charring, and helps protect your laser lens.

How many passes to cut through Glass on the OMTech OMTech CO2?↓

The manufacturer recommends 1 pass to cut through Glass at 40 mm/s and 12% power. If the cut isn't clean, try reducing speed slightly before adding more passes.

Why isn't my OMTech OMTech CO2 cutting through Glass?↓

Incomplete cuts are usually caused by incorrect power, speed, or focus distance. If edges are charred, try increasing speed or reducing power. If the laser isn't cutting through, reduce speed or increase power — or add an extra pass. Also verify your focal distance is correct for the material thickness and that your lens is clean.
