6. Cut as usual. Simply release the trigger assem-
bly 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 in-
stalled, 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.

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.
Drag Cutting With a Hand Torch
Drag cutting works best on metal 1/4" (6 mm) thick
or less.
NOTE!
Drag cutting can only be performed
at 60 amps or less.
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.
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.
3. Keep the torch in contact with the workpiece
during the cutting cycle.
4. Hold the torch away from your body.
5. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing the
trigger. The pilot arc will start.

6. Bring the torch within transfer distance to the
work. The main arc will transfer to the work, and
the pilot arc will shut off.
NOTE!
The gas preflow and postflow are a
characteristic of the power supply
and not a function of the torch.

Piercing With Hand Torch
1. 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 technique that feels most comfortable and
allows good control and movement.
NOTE!
The tip should never come in con-
tact with the workpiece except dur-
ing drag cutting operations.
2. Angle the torch slightly to direct blowback par-
ticles away from the torch tip (and operator)
rather than directly back into it until the pierce is
complete.
3. In a portion of the unwanted metal start the
pierce off the cutting line and then continue the
cut onto the line. Hold the torch perpendicular to
the workpiece after the pierce is complete.
4. Hold the torch away from your body.
5. Slide the trigger release toward the back of the
torch handle while simultaneously squeezing the
trigger. The pilot arc will start.
