The LH1575 FastLaser, Hypertherm Inc.'s second CO2 laser cutting head based on flow-accelerated screen technology, offers expanded cut capacity and cut quality with a minimum 10% to 20% increase in cut speeds on thick mild steel. The patented process delivers optimal gas flow directly to the cut zone, matching beam width and gas flow geometry. Lens change is quick and requires no tools, and the focal length can quickly be adjusted between 5.0 and 7.5 in. The lens is gas-cooled, while the laser head and nozzle are water-cooled. Options include precentered optics and top-mount spring collision protection.
