Cutting Operation
When the torch leaves the workpiece during cutting
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 work-
piece the pilot arc restarts instantly, and the cutting
arc restarts instantly when the pilot arc contacts the
workpiece. (Use the 'Rapid Auto Restart' position
when cutting expanded metal or gratings, or in goug-
ing or trimming operations when an uninterrupted
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 operator
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 / OFF switch to OFF (down).
/
All Power Supply indicators shut OFF. Unplug
the input power cord or disconnect input power.
Power is removed from the system.
