OPERATION 4-6 June 30, 2009
C. Cut as usual. Simply release the trigger
assembly to stop cutting.
D. Follow normal recommended cutting
practices as provided in the power supply
operating 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.
E. 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.
