Trigger Release
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 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 maintain
good visibility of the cutting arc. During operation,
position the legs of the standoff guide against the
workpiece.

Cutting Guide
Using Drag Shield Cup With Straight Edge
The crown shield cup functions best when cutting
3/16 inch (4.7 mm) solid metal with relatively smooth
surface.
C. Drag Cutting With a Hand Torch
Drag cutting works best on metal 3/16" (4.7 mm)
thick or less.
NOTE
For best parts performance and life, always
use the correct parts for the type of operation.
1. Install the drag cutting tip and set the output cur-
rent to 35 amps or less.
2. The torch can be comfortably held in one hand
or steadied with two hands. Position the hand to
press the Trigger on the torch handle. With the
hand torch, the hand may be positioned close to
the torch head for maximum control or near the
back end for maximum heat protection. Choose
the holding technique that feels most comfortable
and allows good control and movement.
4. Keep the torch in contact with the workpiece during
the cutting cycle.
5. Hold the torch away from your body.
6. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing the
trigger. The pilot arc will start.
