Select Current Output Level
1. Place the Function Control Knob in one of the three
operating positions available:
RUN ,
RAPID AUTO RESTART
or LATCH . Gas flow stops.
2. Set the output current to desired amperage with the
Output Current Control Knob.
Cutting Operation
When the torch leaves the workpiece during cutting opera-
tions 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 contacts the
workpiece. (Use the 'Rapid Auto Restart' position when
cutting expanded metal or gratings, or in gouging or trim-
ming 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 amperage,
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 continues
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.
