Laser Overview
The Mariner ™ Controls offers a unique Laser process screen directly integrates to Hypertherm‟s
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™ (Flow Accelerated Screen Technology), utilizes 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 controller, 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.
Note: Refer to Laser Information provided with the FAST Laser™ head for proper operation.
