From Coherent Laser -

For CO2 laser - appears that 150W can cut up to 1/8" steel.


Oxygen assist - assists cutting speed.


  • See Laser Fabrication and Machininng of Materials - [1]


  • Kern Laser 150W laser claims .09" cutting capacity for mild steel with oxygen assist.
  • 100W for 1/40" at 40psi oxygen assist yields 130 ipm
  • Thick steel - this graph indicates 5x increase in cutting thickness from high pressure oxygen assist
