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 attempt 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
workpiece, 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 maintain good visibility
of the cutting arc. During operation, posi-
tion the legs of the standoff guide against
the workpiece.
