when lit separately is equal to 5 lbs. from the segment next to it. Each will show 5, 10, or 15
lbs or more below or above the ideal. When two segments are illuminated together then
the change is half as much or 2.5 lbs. The pressure settings will all be affected by the other
settings for torch, torch length and type of cutting and will require adjustments to the pressure
setting.
Cutting Operation
When the torch leaves the workpiece during cutting operations in the RUN mode, there is a brief
delay in restarting the pilot arc. With the system in the RAPID AUTO RESTART mode, 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' mode when cutting
expanded metal or gratings, or trimming operations when an uninterrupted restart is desired).
With the system in the LATCH mode the main cutting arc will be maintained after the torch switch
is released. To exit or cancel the LATCH mode, press and release the trigger again or lift the torch
from the cutting surface so the arc goes out.
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 Recommended Cutting Speeds With Exposed Tip" 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, to the left as you face the unit from the rear. After a short delay
all Power Supply indicators and fan shut OFF. Unplug the input power cord or disconnect input
power. Power is removed from the system.
NOTE!
To maximize the longevity of the internal electronics, allow the power supply to continue running (without cutting)
until the cooling fan speed changes to slow. This may take a few minutes.
