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, 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.
Drag Cutting With a Hand Torch
Drag cutting works best on metal 1/4" (6 mm) thick or
less.
NOTE!
For best parts performance and life, al-
ways 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.
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.
