As an alternative to the FAST Laser nozzles, a dual nozzle configuration can be used for oxygen assisted cutting of
thicker mild steel, up to 19 mm (3/4"). The standard nozzle and nozzle adapter (104076) must be removed and the dual
nozzle adapter (104372), the dual nozzle, and the dual nozzle shield must be installed. Assist gas pressures for the dual
nozzle will be similar to those used for a standard nozzle. Since the geometry of the dual nozzle face is different from the
standard nozzles, a minor adjustment may be needed to the capacitive height sensor calibration or a slightly higher
stand-off distance will occur.

*The 021081 nozzle is a general purpose nozzle used to cut thick material.
**The 021082 nozzle can be used on thick material that is prone to self-burning.
