6. Cut as usual. Simply release the trigger assembly
to stop cutting.
7. Follow normal recommended cutting practices as
provided in the power supply operator's manual.
NOTE
When the shield cup is properly installed,
there is a slight gap between the shield cup
and the torch handle. Gas vents through this
gap as part of normal operation. Do not at-
tempt to force the shield cup to close this gap.
Forcing the shield cup against the torch head
or torch handle can damage components.
8. For a consistent standoff height from the work-
piece, install the standoff guide by sliding it onto
the torch shield cup. Install the guide with the
legs at the sides of the shield cup body to main-
tain good visibility of the cutting arc. During
operation, position the legs of the standoff guide
against the workpiece.
