OMTech 80W CO₂
Workhorse CO₂ for shops that outgrew 40W — large bed, real production speed
Last updated How we evaluate
Released June 2020
What this machine is for
High-power CO₂ production for sign shops cutting thick acrylic & wood daily
Reference benchmark same job size on every machine so you can compare times fairly.
Laser spot size
~0.15 mm CO₂ spot
Smaller spot = finer detail (frame motion is usually the same across tiers)
Motion precision: 0.01 mm
Sample engrave job
~4–6 min
Filled photo or logo on birch plywood
10 × 10 cm (4 × 4 in)
Sample cut job
~1–3 min
Simple square cut-out from 3 mm acrylic
10 × 10 cm (4 × 4 in)
Times are estimates for the reference job above; your design complexity and settings will change them.
TL;DR
OMTech's 80W desktop/floor CO₂ machines target sign shops and serious makers who need faster cuts on thick acrylic and wood. More power, larger beds, and higher price than K40 class. Expect setup, ventilation, and maintenance — not plug-and-play.
What this machine is for
Production CO₂ laser for sign making and thick material cutting in dedicated workshop spaces.

Beginner notes
Do not buy 80W as a first laser. You should already know you need this power and have ventilation planned.
Pro tips
Install ammeter and water flow sensor early. Keep spare mirrors and lens — production downtime costs more than parts.
