Cutting Operation
When the torch leaves the workpiece during cut-
ting operations with the Function Control Knob in
the RUN position, there is a brief delay in restarting
the pilot arc. With the knob in the RAPID AUTO
RESTART position, when the torch leaves the
workpiece the pilot arc restarts instantly, and the
cutting arc restarts instantly when the pilot arc con-
tacts the workpiece. (Use the 'Rapid Auto Restart'
position when cutting expanded metal or gratings,
or in gouging or trimming operations when an un-
interrupted restart is desired). And with the knob
in the LATCH position the main cutting arc will be
maintained after the torch switch is released.
Typical Cutting Speeds
Cutting speeds vary according to torch output am-
perage, the type of material being cut, and opera-
tor skill. Refer to Section 4T.08 and following for
greater details.
Output current setting or cutting speeds may be
reduced to allow slower cutting when following a
line, or using a template or cutting guide while still
producing cuts of excellent quality.
Postflow
Release the trigger to stop the cutting arc. Gas con-
tinues to flow for approximately 20 seconds. During
post - flow, if the user moves the trigger release to
the rear and presses the trigger, the pilot arc starts.
The main arc transfers to the workpiece if the torch
tip is within transfer distance to the workpiece.
Shutdown
Turn the ON
(down). All Power Supply indicators shut OFF.
Unplug the input power cord or disconnect input
power. Power is removed from the system.
