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 power supply 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
LH21XX 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 only 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.
