Laser Overview
The Mariner CNC offers a unique Laser process screen directly integrates to the
Hypertherm FAST Laser™ head. This feature has the ability to improve Laser setup and
operational accuracy while having the flexibility to fine tune the process specific to the
operator’s needs.
FAST Laser uses an innovative patent-pending design to create a dual flow zone allowing
significantly higher oxygen assist gas pressures in the tightly defined cut zone established
by the beam geometry, without the uncontrolled burning in the surrounding zone
normally induced by increased assist gas pressures. This accelerated high-velocity
oxygen flow along the beam path not only increases cut speed by fueling the exothermic
reaction, but also reduces sensitivity to common plate fabricating conditions and
variables, most notably plate chemistry and condition.
With this technology, Hypertherm has introduced a line of laser cutting heads that utilize
the FAST Laser process to deliver up to a 20% increase in cut speed over standard CO
2
laser heads on plate steel while also significantly expanding the capacity and quality
range of plate laser cutting systems. These combined benefits produce substantial gains in
productivity and unattended operation potential for dedicated plate lasers (4 to 6 kW) –
whether integrated or retrofitted – while also offering expanded capacity range and cost
performance for shared-duty systems (2 to 3 kW). The Hypertherm LH2100 head offers
two different focal lengths: 7.5 and 10.0 inches; the LH2125 adds a 12.5-inch focal
length option for thicker plate. The Hypertherm LH2125/2100 series is used on laser
systems with 1.5” or 2.0” optics. The Hypertherm LH1575 head offers two different focal
lengths: 5.0 and 7.5 inches for 1.5 inch optics.
Integrated with Hypertherm Automation’s Mariner CNC, on-board FAST Laser process
intelligence coupled to process monitoring optics standard on LH-series cutting heads,
achieves improved overall control of the cutting process with fewer system faults and
reduced operator involvement. Dynamic Pierce Control senses and initiates each cut once
the pierce is complete. These combined capabilities maximize uptime while minimizing
total cycle time.
