6. Cut as usual. Simply release the trigger
assembly to stop cutting.
7. 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.
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.

Torch Tip
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 out-
put current to 30 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 comfort-
able and allows good control and move-
ment.
4. Keep the torch in contact with the work-
piece 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.
